Eyeglasses come in all shapes and sizes, and can be made from several different materials. For patients with astigmatism, the lens material and frame shape all play a role in providing clear and comfortable vision.
Below, we’ll explain what astigmatism is and which glasses are best suited for astigmatic eyes.
What is Astigmatism?
Astigmatism is a common eye condition caused by an irregularly curved cornea or lens. It affects about 30% of North Americans.
When the cornea or lens is misshapen, it changes how incoming light is refracted onto the retina.
Symptoms of astigmatism include:
- Blurred vision
- Eye strain
- Headaches
- Difficulty seeing at night
- Frequent squinting when trying to focus on an object
Very often, astigmatism accompanies either nearsightedness (myopia) or farsightedness (hyperopia).
Best Glasses For Astigmatism
Frame Shape and Size
Flatter frames are better for astigmatism. Wraparound or curved frames can bend the light in a way that distorts your vision. Also, be sure to choose a frame that sits securely on the bridge of your nose to keep your vision clear and in focus.
Lens Material
Higher levels of astigmatism often require a thinner type of lens than standard lenses. High index or Trivex lenses are often used for high prescriptions.
Standard plastic lenses are less expensive and can be helpful for low levels of astigmatism.
Specialized Lens Coatings
Every time you order glasses, you have the option of adding on custom coatings to suit your optical needs. Some available options are anti-scratch, UV-blocking, and blue-light blocking.
People with astigmatism may want to opt for anti-glare or anti-reflective coatings to increase the amount of light that enters the eye. Keeping your lenses clean is also important for accessing the most amount of light for a clearer image.
Local Optical vs. Online
When it comes to astigmatism, it’s best to purchase your eyewear from your local optometrist rather than from online sources. Although it may be more affordable to shop online, you’ll miss out on the opportunity to have your glasses adjusted if necessary, and personalized to fit your face.
Purchasing eyewear online also increases the risk of manufacturing errors and ill-fitting features.
