Presbyopia

Definition

Presbyopia (aging of the lens in the eye and the muscles that control the shape of the lens) commonly occurs after age 40, when the lens of the eye becomes more rigid and does not flex as easily. The result is that it is more difficult to read at close range. This normal aging process of the lens can also be combined with myopia, hyperopia or astigmatism.

Presbyopia is a refractive error, which results from a disorder rather than from disease. A refractive error means that the shape of your eye does not bend light correctly, resulting in a blurred image.

Symptoms

• Near objects appear blurred
• Difficulty seeing objects up close
  

The symptoms described above may not necessarily mean that you have presbyopia. However, if you experience one or more of these symptoms, contact your eye doctor for a complete exam.

Treatment

Presbyopia is commonly treated using corrective lenses, such as eyeglasses or contact lenses.
