Glasses for Astigmatism: Here is all you need to know
The chances are that you have heard the word Astigmatism from science classes. Hopefully, you can still recall what it means. If you have forgotten, don’t beat yourself over it. Here is a quick reminder.
Astigmatism is a vision problem that’s caused by irregularities in the cornea or eye lens. This irregularity affects how light is passed through or is reflected by the retina.
Hopefully, that helps. The next question is,
Do you need glasses for astigmatism?
So far, medical reports have shown that not every case of astigmatism require glasses. It’s possible to have astigmatism (at a certain stage) and still have a 20/20 vision.
Like every other part or organ of the body, the eyes also change with time. As such, you should check in with your doctor for regular checkups.
Other than using glasses, an alternative treatment for astigmatism is a corrective surgery, orthokeratology, which involves the use of rigid contact lenses to correct the irregular curvature of the cornea.
Signs that you need glasses for astigmatism
The decision of using glasses for astigmatism is dependent on the clarity of your vision and the stage of your astigmatism. Blurry vision or having strains are the first signs that you need glasses to manage your astigmatism.
Other signs include:
- Having difficulty seeing at night
- Double vision
- Having headaches due to eyestrain
- Frequent squinting
While astigmatism affects people differently, the best time to consider getting glasses is why astigmatism begins to interfere with your daily life.
Before you go on to pick any glass, it’s best to consult with an eye specialist or doctor. An ophthalmologist or optometrist is in a better position to check your eyes and evaluate your vision and prescribe a suitable glass for your condition.
Where can you get glasses for astigmatism?
Suppose your doctor prescribes or recommends glasses for your astigmatism, there is a long list of places you can check.
- Check online
Thanks to the internet, tons of online stores or websites deal with providing lenses for people with astigmatism. However, before you proceed with the transaction, take your time to double-check and confirm that they can deliver your order.
- Check with a local optometrist
If you had visited an optometrist for your checkup, the chances are that you can also order your glasses through them or get them to make one for you (depending on their production capabilities).
From experience and testimonials, buying your glasses from a local optometrist is not the most affordable option but it offers more convenience.
Considering that you may need to go back to your doctor to ensure that the glasses fit and are properly positioned in your eyes, buying astigmatism lenses from a local optometrist is not entirely a bad idea.
To help you find a professional and reliable optometrist to cater to your needs, you can search for eye doctors in your area through the American Optometric Association.
How about retail optometry locations?
Another option to explore when looking for the best glasses for astigmatism is retail optometry locations. Virtually every town has a stand-alone store that deals strictly on the sales of glasses, including glasses for astigmatism.
Also, a visit to some large stores like Walmart may lead you to reliable optometry centers. Such centers or retail outlets can provide you with a wide range of prescriptions glasses for astigmatism.
What are the factors to consider when choosing eyeglasses?
When choosing glasses for astigmatism, there are factors you should consider. While you are at it, bear in mind that the material that was used in making the lenses, the frame shape and the coating used impacts the performance of the glasses.
Typical eyeglasses for astigmatism feature a special cylindrical lens that corrects how light passes through the cornea. While single-vision lenses are mostly prescribed for astigmatism, older patients (those that are over 40 years) often get bifocal.
- Lens material
If you have been to an eyeglasses store, you will notice that the lenses vary in thickness. The idea is that higher prescriptions get thinner lenses. As such, someone with high-level astigmatism will most likely get a high index lens instead of a standard lens.
- Lens coatings
Lens coatings serve as an anti-reflective layer that reduces glare and helps people with astigmatism see better. As we mentioned earlier, astigmatism has to do with how light is reflected on the retina. So, the lesser the glare and cleanliness of your glasses, the better and clearer the vision.
- Frames, shape and size
The frames are intended to make the lenses fit comfortably on the face. High-level astigmatism requires a flatter frame to hold the curve lenses in place because it has more curves in the front which can cause distortion.
The final decision of whether you will be needing eyeglasses for your astigmatism is dependent on the outcome of your doctor’s assessment. If you are given any prescription, you can start by checking online or at local stores near you.
Rounding off, a blurry vision doesn’t always mean one has astigmatism. Allow doctors to test you and rule out other possible health concerns.
