About Clinical Trials

A healthy, young eye is able to focus light from both far and near objects to create a clear image at all distances. By age 45, the eye's natural lens is too stiff to focus on near points. As a result, near tasks like reading or computer work are blurry. This is a natural occurrence that affects us the rest of our life. The clinical term for the loss of near vision is presbyopia (prez-bee-'O-pee-uh). It is possible to have poor near vision, but good distance vision.

Buying a pair of reading glasses is a quick way to improve near vision. While "readers" will help you read a book or dial a telephone number, they will not help you see far objects. Some find putting glasses on to see near and taking off to see far inconvenient.
