Understanding Presbyopia
What Is Presbyopia?

All people will experience difficulty reading, usually beginning in their 40s. Your eye has a lens, which “accommodates” light so that you can see at near distances. With presbyopia, light from a near object enters the eye, the cornea refracts the light and the lens changes shape to accommodate for the decreased focal length of a near object.

This is exactly the same process that occurs when focusing your camera on a near object. Unfortunately this lens within the eye, as it ages, loses its ability to focus for us and we need reading glasses or bifocals. The most popular solution in the past for presbyopia has been bifocals or reading glasses. NearVision CK® is now a procedure that can solve this problem.
