What Is Presbyopia?

Presbyopia is the result of the normal aging of the lens inside your eye.  A refractive error, presbyopia results from a disorder than from disease. The condition commonly occurs after age 40, when the lens of the eye becomes more rigid and does not flex as easily. As a result, it is more difficult to read at close range. A normal aging process of the lens, presbyopia can also occur along with myopia, hyperopia, or astigmatism.
