Astigmatism is currently one of the most common eye disorders patients present to optometrists. As more people are diagnosed with this condition, scientists are hard at work researching how to incorporate a astigmatism prescription into a contact lens.
Contact lenses that correct astigmatism are called Toric Contact Lenses. Although they might look similar to regular soft lenses, toric contact lenses have been specifically designed to help with astigmatism. To understand how toric lenses help astigmatism patients, of course, we need to learn a bit more about what astigmatism is.
Basics On Astigmatism
Usually caused by the lens within the eye or the cornea, that are shaped more like a rugby ball than a football, astigmatism is characterized by symptoms like blurred vision, frequent headaches, and difficulty focusing. Patients typically notice warning signs of astigmatism early in life, but onset could begin at any age. Most people with astigmatism have some other type of refractive error like myopia.
Why Aren’t Regular Soft Lenses Enough?
Standard soft contacts have a spherical shape, which means the focal power is the same no matter where you’re looking through your lenses. Toric lenses, however, are usually weighted on the bottom and have different focal strengths in different areas. These contrasting focal powers can fully correct the astigmatism existing in a patient’s corneas.
Fitting toric lenses is often more difficult than spherical lenses, so patients are encouraged to try a few different brands of toric lenses to find what works for them. As always, discuss any concerns you have with your astigmatism or toric lenses with a trusted optometrist.
