Astigmatism is a common vision condition that develops when a person has an irregularly curved cornea or lens. It results in blurred vision. Many brands offer specific eyeglass lenses to help correct astigmatism.
This article reviews some of the best brands that offer glasses for astigmatism and looks at some essential information for people who are considering purchasing glasses online.
Astigmatism is a vision problem that occurs when light is incorrectly bent, or refracted, as it enters the eye. When the cornea is not smooth, or if the cornea or the lens is unevenly curved, light refracts improperly, leading to blurred, distorted, or double vision.
According to the American Academy of Ophthalmology, symptoms that might indicate astigmatism include:
- blurred vision
- eye discomfort
- squinting to see things clearly
- eye strain
Store-bought reading glasses are not suitable for people with astigmatism. Individuals must use prescription glasses or contact lenses to correct their vision.
To provide an accurate lens prescription, an eye doctor will check a person’s visual acuity and perform a refraction. They may also check the shape of a person’s cornea using keratometry or topography.
The cylinder or astigmatism section in a person’s prescription indicates the additional power required to correct their astigmatism.
The eye doctor may also discuss the option of refractive surgery, such as laser-assisted in situ keratomileusis (LASIK), to correct astigmatism.
Several lens materials are suitable for different refractive errors and levels of prescription. They include:
- Plastic lenses: Also known as CR-39, these are often the most cost effective lenses. They are suitable for lower level prescriptions, but they are not impact resistant.
- Trivex lenses: These durable, lightweight, and thin lenses are also suitable for lower level prescriptions. They are impact resistant, which may benefit people at risk of eye trauma, such as athletes.
- Polycarbonate lenses: These are similar to Trivex lenses. They are highly durable are lightweight. They offer UV protection and are also impact resistant. They are suitable for low-to-medium level prescriptions.
- High index lenses: These are particularly suitable for higher level or strong prescriptions. Their material is thin and light.
- Glass lenses: These are still available, but eye doctors tend to avoid them due to their weight, thickness, and risk of breakage.
A person may also choose glasses with extra coatings, such as UV protection, adaptive lens technology, and blue light blockers.
Other things to consider
In addition to the lens material, a person may also wish to consider:
- cost and insurance coverage
