Your retinas, the light-sensing portion of your eyes, contain a central layer called the macula. As you age, the macula may deteriorate over time and cause significant and irreversible central vision loss. If you have macular degeneration, you will lose the ability to see fine details. However, your peripheral vision may remain intact. Macular degeneration is the leading cause of deteriorating vision among adults older than the age of 60.
Tobacco use, high blood pressure, heart disease, high cholesterol, obesity and family genetics may all contribute to macular degeneration. Females, Caucasians and those with lighter eye colors are also at higher risk.
