Reading Glasses after Age 40

Presbyopia is a normal part of the aging process and usually occurs about the age of 40. As the body matures, the normally soft, flexible lens becomes hard and has difficulty focusing on close objects. Reading vision becomes blurred and difficult.

Bifocals and reading glasses, which aid the eye in focusing on close objects, are used to treat presbyopia.

Since the laser has no effect on the lens of the eye and can not improve vision due to presbyopia, people who have had PRK and have or develop presbyopia will need reading glasses for small print.


Monovision is a technique (used for people with presbyopia) that corrects vision in one eye and adjusts the other eye (usually the non-dominant eye) for reading vision. Your pre-surgery testing and discussions with the doctor will help determine if monovision is an option for you to consider.
