What Is Eyesight Failure

The main eyesight conditions that fall into the eyesight failure category with aging include:

• Presbyopia
• Cataract
• Glaucoma
• Macular Degeneration

Presbyopia

Changes in eyesight start around age 10, and by 40, most people have symptoms of Presbyopia. Presbyopia is the loss of the ability to focus on close objects; making reading and close-up work more difficult.

Cataract

A cataract is an opacity that develops in the lens of the eye or in its envelope. Age-related cataract may result in increased power of the crystalline lens, causing near-sightedness [myopia]. It can also lead to gradual yellowing and opacification of the lens; reducing the perception of blue colours. Untreated Cataracts can cause vision loss and blindness.

Glaucoma

Glaucoma is one of the leading causes of blindness in the U.S. It most often occurs in people over age 40. Glaucoma cannot be prevented, nor can vision lost to glaucoma be restored. If, however, an annual examination routine is followed, glaucoma can be controlled, as long as it is diagnosed early.

Macular Degeneration

Macular degeneration is where the center of the inner lining of the eye, known as the macula area of the retina, suffers thinning, atrophy, and in some cases bleeding. This can result in loss of central vision, which entails inability to see fine details, to read, or to recognize faces. Macular degeneration is leading cause of central vision loss (blindness) and in the United States today for those over the age of fifty years.
