Presbyopia

Your clear lens sits inside the eye behind the colored iris. When you are young, the lens is soft and flexible. This lets you focus on objects both close-up and far away. After age 40, lens becomes more rigid and it cannot change shape as easily. Presbyopia is a progressive condition; it affects everyone at some point and there is no way to stop or reverse the normal aging process. You can also view presbyopia as the age-related loss of zooming.

Monovision (blended vision), where one eye is corrected for distance and the other eye is corrected for reading. When we set the eyes for monovision, the dominant eye is set for distance and the non-dominant eye is set for near. The main benefit of monovision is the ability to see distance, intermediate, or near without having to resort to using glasses. Monovision can be done through lasik or refractive lens exchange.
