The need for reading glasses as you get older is called presbyopia. When you have LASIK, you and your doctor may decide to leave one eye slightly nearsighted. This is called monovision, and may allow you to maintain your ability to read after presbyopia begins. Your other eye will be fully treated for distance vision. Gaining this near vision means giving up some distance sharpness. (Many people have already elected monovision correction with their contacts or glasses.) Monovision is helpful for near-tasks such as scanning a menu or article, but not for reading fine print or reading for a prolonged time. For active individuals, such as those who play golf or tennis, or who drive a great deal at night, monovision may not be suitable.
During your consultation, you and your eye doctor will decide which choice is best for you.
