What Are Astigmatism Contact Lenses?
Last Reviewed: January 16, 2020
Astigmatism glasses and lenses bend the light to fall on a different angle into your eyes. They are designed to focus the light better onto the retina.
The problem with both is that it will not correct the root causes of astigmatism. They merely accommodate for the incorrect angle that the light falls into your eyes.
To correct and get rid of glasses and contact lenses you
have to understand the true root causes. The distortion of the lens happens because your lens is too weak.
The true root causes of astigmatism cause a weak lens that distorts, which is the reason why the light falls into your eyes incorrectly. You can find out what your specific root causes are when you click here.

The Questions Answered In This Article:
Common Customer Questions:
Astigmatism contacts are a specific type of lens that corrects the refractive error of astigmatism. Astigmatism lenses come in three different types of correction.
Yet each type of astigmatism lens achieves the same goal;
To accommodate for the refractive error of astigmatism. That refractive error is due to
- a distortion in the lens (lenticular astigmatism), or
- a distortion of the cornea (corneal astigmatism).
In both cases, the lens will redirect the light into the eye in a way that all light rays merge and focus directly on the retina.
Are Astigmatism Contacts Necessary?
Astigmatism is a different refractive error than myopia or presbyopia/hyperopia. The refractive error is due a distortion of the lens (lenticular astigmatism) or the cornea (corneal astigmatism).
So to correct the incorrect focal point of the light falling into the eye, astigmatism requires a different type of correction than near- and farsightedness. Thus astigmatism lenses are necessary if you don't improve your condition naturally.
Using lenses will reduce headaches, fatigue, and blurry vision. And they will keep you safe in traffic.
But they are only necessary if you don't improve astigmatism naturally. That's always the preferred option.
Are Astigmatism Contacts More Expensive?
As always, the price depends on the brand. It depends on the quality. And it depends on the complexity of the prescription.
In general terms, you will find astigmatism a bit more expensive because the correction is not as straightforward as myopia or farsightedness. But you are able to find cheap alternatives on the Internet.
If the cost concerns you, make sure you check out our article about how to correct astigmatism naturally.
Are Astigmatism Contacts Thicker?
Astigmatism lenses are a different shape altogether. As usual, if the prescription is high, the lenses will need to be thicker and noticeable than lighter prescriptions.
It also depends on the type of astigmatism you have. If it's a complicated and complex prescription you will require custom fittings or stronger fittings.
So this is not a straightforward question. It depends on the complexity and severity of your condition.
Are Astigmatism Contacts Uncomfortable?
That lies in the eye of the beholder... literally!
Some people don't mind contact lenses. Others can't handle them. So it will be a trial and error for you to find out. Nobody can tell you if astigmatism lenses will irritate your eyes.
Because your eyes are unique. Your life is unique. And how your eyes will respond to a foreign body in them all day long is impossible to predict.
If you have severe, irregular corneal astigmatism your toric lenses, or strong custom fit lenses, can get very uncomfortable.
But again, you have to see how it will work with your conditions for your eyes.
So let's discuss toric lenses while we are at it...
What Are Toric Lenses For Astigmatism?
Toric lenses are the most popular type of contact lens for people with astigmatism in the US. The differ from spherical contacts that are used for near- and farsightedness.
Normal contact lenses, known as spherical contacts, are shaped like a slice of a ball. So it’s like an outer layer of an onion.
Toric lenses are shaped like an outer slice from a donut. So the are shaped like a ring that pushes the corneal or lens into the desired shape.
So wearing toric lenses without astigmatism is not a great idea. Because the correction is only applicable for astigmatism. Only astigmatism requires such a forceful correction of the cornea or lens.
So, are toric lenses for all strengths of astigmatism?
Yes, there are toric lenses for high astigmatism, mild astigmatism, as well as severe astigmatism. There are multifocal toric lenses for astigmatism. Plus you get toric lenses for astigmatism that are colored ones to change your eye color.
Why Do You Need Toric Lenses For Astigmatism After Cataract Surgery?
Corneal astigmatism is a side effect of cataract surgery. So toric lenses for astigmatism are prescribed to help reduce and ease astigmatism that occurs after the surgery.
If astigmatism stays as a permanent corneal distortion the lens will obviously become a permanent necessity, rather than a temporary fix to ease it off.
Are There Circle Lenses For Astigmatism Without Toric?
Not really. Toric lenses are circle lenses.
What Are Toric Intraocular Lenses (IOL) For Astigmatism?
Intraocular lenses (IOL) for astigmatism are implants that are placed around an artificial lens implant for cataract to correct any astigmatism that may be present in the eye.
It is supposed to correct near- and farsightedness at the same time.
The problem is that when the cylindrical or spherical power changes, the patient will need contacts or glasses again. Because an intraocular lens is simply a type of contact lens that is implanted permanently.
Once the prescription changes, the implant can’t be replaced easily. So you’ll be stuck with a permanent correction that is now incorrect.
Are Toric Lenses Necessary For Astigmatism?
No. There are alternatives for regular, mild, lenticular astigmatism. But for severe, irregular, corneal astigmatism this may be the most comfortable to wear.
Toric lenses are very strong lenses that are kind of custom fit to smooth out corneal distortion. That's why they may be necessary for corneal astigmatism.
So, if they are necessary depends on whether you have corneal astigmatism or not. Then, is it severe? Is it irregular? And is it really necessary to use toric lenses?
And, if any of the other lens type options would work for your eye conditions.
Do you have other options?
Before you jump into toric lenses, be sure to find out, if you can improve your astigmatism naturally first. Click here to get started.
Yet there are other options available. Toric is just the most common type of contact lens purchased for astigmatism in the US.
Are Toric And Astigmatism Lenses The Same?
No. Astigmatism lenses correct a refractive error. They redirect the light into the eyes so that all light rays falling into the eye merge exactly on your retina.
Toric lenses also correct an error. But they keep the cornea in a specific shape. They smooth out corneal distortion of damage.
So astigmatism lenses will not work when you require toric lenses for your correction. And toric lenses can be the solution for some specific, strong cases of astigmatism.
Are Toric Contact Lenses For Astigmatism The Same Price?
Because toric lenses need to be more custom fit than normal spherical contact lenses for near- and farsightedness, they will cost more.
But there are even more expensive options if a patient requires custom contact lenses fit specifically onto the eye.
Always compare the cost to the value you are getting. How often will you have to renew your prescriptions, and what price are all the maintenance costs.
The cheapest long-term solution will always be to get rid of astigmatism naturally. Natural astigmatism correction is possible in most cases. Click here to get started.

What Are Non Toric Lenses For Astigmatism?
1. Gas Permeable Contact Lenses:
This type of contact lens is spherically shaped. Meaning it covers the cornea just like a soft lens for myopia would.
The difference is that the lens is rigid. It doesn’t adapt itself to the distorted cornea. It forces the cornea to smooth out. The pressure is sitting tightly in place so that no rotation is required like with toric lenses.
The vision through GP or RGP lenses is supposed to be crisper and sharper than with toric lenses. On the flipside; the lens is a bit thicker and causes a stronger sensation in the eye. Hence, it takes more time to get used to this type of lens, and some patients can’t handle the sensation.
Gas permeable contact lenses (GP or RGP) need to be custom fitted. Therefore the lens is more expensive than toric and soft lenses. Because each lens is custom-made for the customer.
So for GP lenses it is true that an optician is an expert in the grinding of lenses and fitting of glasses.
So the initial investment, as well as the replacement costs, are both higher.
In the case of irregular types of astigmatism and with severer strength, a client will require gas permeable toric contact lenses. These force the cornea into shape while accommodating for a specific axis distortion at the same time.
2. Hybrid Contact Lenses
This type is a fusion between soft lenses on the outside and gas permeable rigid lenses on the inside. The advantage is a sharper vision from the strong, forceful correction of the GP’s, combine with wearing comfort of the soft lenses around the correction.
As a result, the lens is larger than GP lenses, but not larger than toric lenses. But they have smoother and softer edges than normal gas permeable ones. Plus, they stay better in the eye than normal GP’s.
The custom fitting – cost equation for hybrid lenses is the same like gas permeable ones. They are custom-cut for each eye, so the fitting and manufacturing is cost more than soft lenses. The investment and running costs are very similar to GPs. The difference is the increased comfort to wear the lenses.
One thing to take note of; gas permeable lenses and hybrid lenses do not need to be changed as often as soft lenses. So there is a cost saving factor here.
Yet to constantly have a foreign body cover up the cornea restricts important oxygen from reaching the cornea. That, in effect, will harm the cornea over time. Plus, it is likely to increase irritation in the eyes, as well as the progress to dry eyes.
So while it is a cost saving plus, it’s an eye health concern.
Are Astigmatism Lenses Thicker?
Because of the type of correction gas permeable lenses force onto the eye, they are thicker than other types of lenses. Especially thicker than soft lenses.
The reason is that the lens is forcing the cornea to smooth out. The lens is not simply accommodating for the refractive error, it’s forcing a shape onto the cornea. Therefore the material is more rigid and thicker.
The advantage is that the contacts do not need a direction. The disadvantage is a compromised wearing comfort.
Are Astigmatism Lenses Single Vision?
That depends on what you need. The prescription lenses will correct double vision (one of the definitions of astigmatism) and make sure the patient to correct the refractive error to see a single image. That’s the whole idea of contact lenses to correct astigmatism.
But they can correct multiple eye conditions at the same time. It is possible to correct myopia with astigmatism at the same time. Or astigmatism with farsightedness too.
Are Astigmatism Contacts Weighted?
Some toric lenses are weighted on the bottom. It makes the astigmatism correction with lenses easier due to the lens tilt required to correct the condition.
If there is some weight in a lens, it makes it easier to work out how to put in the astigmatism contact lenses.
Since toric lenses can correct astigmatism in the lens or cornea they have to be fitted in a certain direction to correct the right axis. Therefore weighted keeps them better in place.
Why Are Astigmatism Contacts So Uncomfortable?
That depends which lens you use to correct astigmatism. Most of the time astigmatism contacts hurt when you do use gas permeable contact lenses because the correct astigmatism more forcefully than toric lenses.
If you are wearing toric lenses and can’t handle the comfort, you can try GP lenses or hybrid lenses. But chances are that your eyes just don’t like the foreign body in there constantly.
Also, astigmatism contact lenses are often a root cause for dry eyes. So if you get a lot of dry, irritated, and itchy eyes, you may need to look at glasses as an alternative.
Because it’s best to avoid contact lenses, if your eyes feel uncomfortable. In this case, you would be best advised to starting improving your astigmatism naturally, so you don’t need glasses and contacts as all.
That would also be the best for dry eyes due to contact lens use. Because a truly holistic method like the Pure Vision Method™ will help you to get rid of dry eyes at the same time. So, click here to get started.
Are Astigmatism Lenses More Expensive?
Astigmatism lenses need to correct the refractive error differently compared to regular contacts. There is no axis to consider without astigmatism. Meaning the lenses can be mass produced much easier. Because for contacts without astigmatism, there are more customers with the exact same requirements.
Soft lenses for myopia and farsightedness are all on the same axis. But that’s different for astigmatism contact lenses.
So with regular contacts, the correction is simple. If you want to correct astigmatism with contact lenses your need is unique to you. It’ll be very hard to find a person with the same contacts like you. The need of the lens is tailored to your own needs.
So to correct astigmatism with contacts is a custom-fit job. That increases the price. That’s why are astigmatism lenses more expensive. And that’s why are astigmatism contacts so expensive in general.
The custom fitting and tailor-made aspects are driving up the manufacturing cost.
How Much Are Astigmatism Lenses?
As usual, that depends on the type of lens you opt for. Plus, it depends on your specific need. And it depends on the brand or lens manufacturer you choose.
Of course, it also depends on your provider that tests your eyes during your astigmatism test, writes your prescription, and is selling you the lenses.
Usually, because gas permeable lenses and hybrid lenses are more custom fit than toric lenses, they will attract a higher cost.
So for astigmatism, toric lenses may be your cheapest and most cost-effective option.
But if the price is your main concern, cure astigmatism naturally, so you get rid of your need for lenses altogether. It’s easy and works for most people.
Are Astigmatism Contacts Worth It?
Only you can answer that question for yourself. Is the appearance gain worth the cost and the eye health impacts?
That question is too personal to answer. Every patient will have to decide that cost value equation of astigmatism contacts for themselves.
The most cost-effective and valuable way to treat astigmatism is to get rid of it altogether. In this case, you get the best of all worlds.
Better eye health, better appearance because you don’t need astigmatism glasses, and of course more energy, better health, more confidence and self-esteem, and much better focus.
So there is really nothing to lose except your glasses or contacts. Click here to learn more.
How Are Astigmatism Contacts Different?
Astigmatism contacts differ from normal soft lenses for myopia or farsightedness in that they have to accommodate for an axis distortion. Meaning the refractive correction is different and almost unique for every eye with astigmatism.
In some cases, it comes down to a lens distortion (lenticular astigmatism). In other cases, it’s due to a corneal distortion (corneal astigmatism).
So, especially in severe cases of corneal astigmatism, the cornea needs to be smoothed out and forced into shape with rigid gas permeable contact lenses.
If that’s not the case, the astigmatism lens needs to sit in a specific direction. Otherwise, the correction is at the wrong angle and will make vision even worse.
For normal soft lenses, there is no directional requirement. Hence the lens is easier to fit and can easily move around within the eye.

How Do Astigmatism Contact Lenses Work?
Astigmatism contacts work by bending light into the eye so that the light rays merge and combine in one focal point right on the retina.
With astigmatism, that focal point moves in front of or behind the retina. Therefore astigmatism is corrected in the lens by redirecting the incoming light.
Obviously, the strength of the correction needed will affect lens thickness. Meaning the more correction a patient needs, the thicker the lens will turn out.
Also, if there are multiple distortions at the same time, or the corneal distortion is very strong, the thickness of the lens will also increase fast.
How To Put In Astigmatism Lenses?
Depending on the type and angle you may need to get the lenses fitted by your eye care professional.
If your lens is out and you do not know how to put it back in, go to an eye care professional nearby and ask for help. The Internet, Yahoo Answers, Quora, and YouTube are not good options here because you never know what type of lens the person answering your question is fitting into their eye.
Plus, your needs and angle may be totally different.
So, this is clearly a case to seek professional help. Nothing else will do. Because fitting your astigmatism lens incorrectly can do a lot of harm. So make sure you seek professional help and guidance with that.
What Is The Advantage Of Wearing Contact Lenses Instead Of Glasses?
So, what is the difference between glasses and contact lenses? The end result is the same. Both types of correction help the eye to focus the light right on the retina.
The difference between lenses and glasses comes down to physical appearance. Plus there is a difference in eye health as well.
So, the advantage of contacts is that the user doesn’t have glasses restricting the visual field. Plus, he or she will likely feel more attractive without glasses.
The downside is that there is a foreign body in the eye, which is causing a lot of irritation, itchy eyes, and dry eyes. Plus, it restricts oxygen from getting to the cornea. So it may make the condition worse over time.
Which Is Better For Astigmatism; Glasses Or Contacts?
For your eye health – glasses. Hands down, the benefits outweigh any advantages contacts may present. That’s true for a condition like myopia or farsightedness where the correction of the lens is way less invasive.
But it holds especially true for astigmatism. Especially when the issue is with the cornea. That cornea needs as much oxygen and direct, healthy sunlight as possible. It should definitely not be shut out and sealed off by a piece of silicon in the eye.
What makes contacts better than glasses is the increased beauty aspect. But which is better; good eye health, or more beauty?
If beauty is your concern; the best is get rid of astigmatism naturally once and for all. Most of the time it’s possible. So click here to find out, if you can fix your astigmatism naturally.
That way you get the best of both worlds; more beauty, and impeccable eye health. What are you waiting for? Click here now
So, contact lenses are not better than glasses. On the contrary, glasses are better than contacts. Also, long-term lenses are not cheaper than glasses. They cost more. Especially if you treat your glasses and frames well.
Contact lenses become more expensive than glasses fast.
Which Is Safer; Glasses Or Contact Lenses?
Hands down – glasses. You can’t hurt your eyes easily. Plus you can’t get dust or sand under it to scratch your eye. And there are so many benefits.
To get rid of glasses, don’t opt for contact lenses. Cure astigmatism naturally and holistically, and you are all set and done!
What Is The Difference Between Prescription For Astigmatism Glasses And Astigmatism Contact Lenses?
There is no difference between contact lenses and glasses prescription. Astigmatism contacts vs astigmatism glasses prescription; it is the exact same. Your eyes need the same correction in both cases.
What Are Astigmatism Glasses?
Astigmatism glasses are specific prescriptions that correct a cylindrical refractive error. As opposed to
the spherical refractive error of near- and farsightedness.
So astigmatism glasses are glasses with a specific lens to correct corneal or lenticular distortion. Depending on your condition, they will correct one or more refractive errors.
So, treating astigmatism with glasses can be a very customized prescription.
Are Astigmatism Glasses Necessary?
If you have astigmatism, yes.
Well, of course, you can opt for contact lenses or one of the types of astigmatism surgery. But if you want to correct your refractive error with glasses, lenses for myopia or farsightedness alone won't do it. They correct the wrong angle of refractive error.
There are people on YouTube that claim you can do so with a too strong prescription. But doing so will do your eyes more harm, and never any good.
Are Glasses For Astigmatism Different?
Obviously, the frames are not. It's just about the lens and the shape for of the lens. You need astigmatism lenses for glasses. Because astigmatism is a distortion of a specific degree along the axis of the eye, a spherical correction won't help.
The correction has to accommodate for the distortion along the axis. For near- and farsightedness there is no degree of correction because the refractive error is always on the spherical plain.
What Are Problems With Astigmatism Glasses?
The biggest problem with astigmatism glasses is adjusting to glasses when you first get them. Plus, adjusting to new glasses when your prescription changes.
The problem is very simple. Your vision is supposed to get better with glasses. Yet your mind is not prepared for the artificial magnification. Your mind got used to the new set up.
The other problem is that most of the time new glasses are too strong. Optometrists like to overprescribe. That's when everything gets blurry with glasses.
When everything is blurry, even with glasses. For glasses to be really accurate all day long, you would need to have a dynamically changing strength. Because your eyesight is fluctuating throughout the day.
That's why glasses are not working. At least they are off for most of the day. That's also why you can get dizzy with glasses easily.
Other problems with glasses for astigmatism are headaches. When you are asked to wear glasses that are off most of the time, often too strong, headaches are foreseeable.
So to correct astigmatism with glasses is a delicate thing. They can help and focus on reading. But at the same time, you make astigmatism worse with glasses.
You lose your ability to operate without glasses altogether. Even though you can correct astigmatism with no glasses. So the trick question to answer is; with astigmatism, when should you wear glasses?
The preferred way to go about it is to cure astigmatism without glasses. Because you can start correcting astigmatism without glasses starting today.
But you will never be correcting astigmatism with glasses in a way that you fix it. You can only fix it without glasses. Fixing astigmatism with glasses doesn't exist.
You merely correct the refractive error. But when you take the glasses off, that error is still there.
After you truly cure astigmatism naturally, though, whether you wear glasses or not, the refractive error is gone.
So whether you are interested in glasses or contact lenses because of astigmatism. If you weigh up glasses vs contacts.
The best is to improve astigmatism without glasses altogether, so it's gone.
How Do Astigmatism Eyeglasses Work?
Astigmatism eyeglasses work by redirecting the light rays that are falling into the eye. The focus point of the merging rays of light is supposed to be right on the retina. With astigmatism, that point is too early in front of the retina (myopic astigmatism). Or too late, behind the retina (hyperopic astigmatism).
The glasses ensure that the light bends into the eye so that all the rays merge in one focal point right on the retina to create a sharp image.
Without it, there will be two stimuli for the same point, creating double vision.
How Are Astigmatism Glasses Lenses Measured?
Astigmatism glasses are made after the lens of the person is measured. The important thing to determine is the refractive error. Whether it is caused by the cornea (corneal astigmatism) or by a distortion in the lens (lenticular astigmatism).
So the optometrist or eye specialist will determine the type of astigmatism. Then he or she will place different glasses in front of the patient to get the glasses lens measured.
After the prescription is established the order will be sent out to the lens manufacturer to get the glasses lenses cut.
So many patients ask "are glasses lens prescriptions the same as contacts?". The answer is yes.
Astigmatism glasses and contacts are the same types of lens. The same correction is required. The only difference is whether the lens is within a frame, or sitting directly on the lens of the patient.
Are Astigmatism Glasses Thick?
Obviously, the stronger the prescription the thicker the glasses. But astigmatism glasses are not thicker than reading glasses or glasses for myopia.
Also, in today's world, glasses are not as thick as they used to be. With laser technology it is easier than ever to cut lenses reasonably thin. No matter how strong the prescription is.
What Are The Thinnest Lenses For Astigmatism Glasses?
A very light, regular lenticular prescription that is cut into plastic lenses. Glasses usually require more thickness to stay stable. Plastic can be cut more thinly while still staying safe.
Regular, lenticular astigmatism is the simplest form of correction. So a light prescription for that astigmatism type would be the thinnest option.
If you are inquiring about a manufacturer that produces the thinnest lens overall for any type of astigmatism, ask your prescribing optometrist for help.

What Is The Cost Of Astigmatism Lenses For Glasses?
Obviously, that depends on many factors. Condition and quality being tow of them. So the cost of astigmatism lenses can vary greatly depending on where you go shopping.
There are cheaper options online. But you have to be sure that they provide quality glasses.
It's still better to save that money for the rest of your life and just get rid of your glasses altogether.
Are Astigmatism Glasses More Expensive?
Astigmatism glasses are usually more complicated than just reading glasses or glasses for myopia. Because the refractive error has a different angle for every patient.
Myopia glasses and reading glasses are spherical, meaning it's just a straight ahead correction. The cylindrical correction of astigmatism is a refractive error off-axis. But that degree and the amount of correction differs from person to person.
Plus, there is a difference between the lenses for corneal astigmatism or lenticular astigmatism. And things get even more complex with irregular astigmatism where the lenses need to accommodate for multiple angles at the same time.
How Much Are Astigmatism Glasses? How Much Do Astigmatism Glasses Cost?
That depends on where the glasses are for sale. Online astigmatism glasses do cost less.
But it still depends on the strength. It depends on the complexity of the prescription. It depends on the type of astigmatism.
And of course, it depends on the chosen frame.
But the costliest part of astigmatism glasses are usually the glasses lenses. Unless you opt for a really expensive designer frame where the sky is the limit.
Yet it is hard to give a definite price without seeing the exact prescription, and the type of lens material you prefer. All of these will influence the price.
How Much Is It To Change Astigmatism Lenses On Glasses?
Again, that depends on the exact condition you have. Is it regular or irregular astigmatism. Do you have corneal astigmatism or lenticular astigmatism?
Do you have mild, strong, or server astigmatism? Do you have other conditions with astigmatism? So there are a lot of details when you want to replace lenses in glasses.
And do you prefer glass lenses or plastic lenses for glasses? Both have advantages and disadvantages.
So, there is no straight forward answer to how much is it to get new lenses in glasses. It is cheaper to put lenses in glasses than getting new glasses with frames. But to put prescription lenses in glasses is still a costly activity.
Is It Possible To Replace Astigmatism Lenses In Glasses?
Some website visitors are wondering whether it is possible to replace the lenses in glasses at all. And most of the times it is.
Sure, sometimes frames are too beaten up to be used again. But most of the time it should be possible.
There is also the possibility that new lenses won't fit an old frame. But that's a rare case.
Where Is The Cheapest Place To Get Lenses For Astigmatism Glasses?
Most likely, the cheapest place to order lenses is the internet. But you have to be careful and make sure that the quality is good enough.
Other than that, you will need to do some research in your local area to find the most cost-effective provider that offers the best quality at the lowest price.
With astigmatism lenses, cost shouldn't be your only concern. Quality is an important factor as well.
If cost and cost saving is such an important issue for you, it's time to investigate natural astigmatism. That way you never have to invest in glasses again.
Why Are Glasses And Astigmatism Lenses So Expensive?
Because astigmatism is unique to every patient. It's very difficult to find the same strength and axis values in two different people. So every astigmatism lens has to be cut uniquely for the glasses of the patient.
With reading glasses or myopia manufacturers can mass produce certain strengths. The angle is the same for all people.
Not so for astigmatism. So the largest portion of the cost will be equipment cost. These lenses have to be cut with ultra precision and modern equipment. Manufacturers recover their investments with every pair of glasses.
Plus, with astigmatism, the equipment has to be calibrated for every client. Lenses can't be mass manufactured. So the setup cost per pair of glasses increases by a lot. Because calibration is the most time-consuming part of the process.
What Are Lenticular Lenses For Astigmatism Glasses?
Lenticular lenses are designed to correct lenticular astigmatism. Meaning the astigmatism is due to a distortion of the lens, rather than a distortion of the cornea.
Therefore the lens is specifically designed to help the light bend correctly into the eye. Making up for the astigmatism distortion of the lens.
What Is The Difference In Lenses For Astigmatism Glasses?
Besides lenticular lenses, there are also corneal lenses for astigmatism. In this case, the lenses of the glasses are accommodating for a corneal distortion.
Meaning that the distortion, the cause of astigmatism, is in the cornea. Therefore the astigmatism glasses have to correct the corneal distortion.
Also, there are glasses for the different types of astigmatism, such as irregular and regular astigmatism. Each condition requires slightly different lenses for the glasses.
When Does Astigmatism Require Glasses?
There are two scenarios here:
- you don't want to improve astigmatism and fix it naturally
- you do want to get rid of astigmatism naturally
First case:
Here you will need glasses as soon as the symptoms of astigmatism start to inhibit your life. Do you get headaches? Do you have problems to read? Are you driving safely? Are you operating heavy machinery with double or blurry vision?
If you have distorted vision and know it's astigmatism then you need to use glasses. To keep yourself and your environment safe.
That's unless.
2. you want to improve astigmatism naturally. Then you don't need glasses at all.
With the first sign of astigmatism, starting with the first symptoms of astigmatism, check if natural methods can work for you. Click here to find out.
Then use a truly holistic astigmatism improvement program to improve your eyesight naturally. That way, you never have to worry about glasses again.
When To Wear Astigmatism Glasses?
Again, as just explained. If you don't want to improve astigmatism naturally, so you get rid of it altogether, start wearing glasses as soon as symptoms appear.
To keep you sane and safe. Plus, to keep your environment safe.
Otherwise, start to improve your astigmatism naturally, so you never have to worry about glasses ever again. Click here to get started now.
Where Is Astigmatism On Prescriptions?
The way to prescribe astigmatism glasses is the cylindrical value. It's abbreviated with CYL. That value describes how strong the correction needs to be.
Plus, it explains if your focal point is in front of the retina (myopic astigmatism). Or if the light rays merge behind the retina (hyperopic astigmatism).
If it's in front, so myopic astigmatism, you'll see a value starting with a minus. It's a minus correction for astigmatism.
In the case of hyperopic astigmatism, the correction will be plus glasses.
The other part of the astigmatism prescription is the axis value. It defines the angle at which the cornea or lens is distorted and bends the light rays incorrectly.
So, an example would be:
CYL: -3 ; AXIS: 85 = myopic astigmatism that requires a 3 diopter correction at 85 degrees.
What Is The Best Way To Clean Astigmatism Glasses Lenses?
Either use some dedicated, environmentally friendly wipes. Or better, use a damp cloth with some environmentally friendly dishwashing liquid and just wash your glasses.
Then wipe them dry with an appropriate microfiber cloth that doesn't leave streaks. And voila!
Just make sure you don't use harsh chemicals. Our oceans really don't need harsh cleaning stuff to clean your glasses. It's too easy to do that well, AND take care of our environment...
