Common Vision Conditions
Astigmatism is a vision condition that occurs when the front surface of your eye, the cornea, is slightly irregular in shape. This irregular shape causes light entering the eye to “split” into two separate parts instead of focusing to one precise point on the retina.
Blurred vision at distance or near
Blurring of Fine Detail
May be present by itself or with both Near and Farsightedness
Contact Lenses for Astigmatism
It is a common misconception that a person with astigmatism is unable to successfully wear contact lenses. With today’s advances in lens design, people with astigmatism are more likely able to wear contacts successfully.
Astigmatism does require a special type of contact lens. Because the light is split into two separate focuses, a lens with two different power curves is needed. These lenses are called toric lenses. These lenses are more complex and require more time and expertise to be fit properly so that the patient has good vision.
What is 20/20?
20/20 is considered normal vision. The term “20/20″ represents the smallest target in angles that an individual is capable of resolving. The result is expressed as a fraction. 20/20 means that an individual has the ability to see from a distance of 20 feet (considered optical infinity) what the normal eye would see at that distance. As another example, 20/40 would mean that a person sees at 20 feet what the normal eye could see at 40 feet.
