Eye Disease Resources
The largest generation in history is reaching the age where eye diseases become more prevalent. The number of older Americans has increased more than tenfold since 1900, when 3 million people were age 65 or older (4% of the population). By 2030 the U.S. Census Bureau estimates that 20% of Americans will be 65 or older.
Prevent Blindness estimates that the number of Americans with age-related eye diseases and the resulting vision impairment is expected to double within the next three decades. Already, 30 million suffer from dry eyes, and 1.6 million feel the effects of macular degeneration. And it's estimated that there are 105 million cases of glaucoma worldwide; many undiagnosed and untreated.
Regular eye exams are an important way to detect disease in early stages, and provide proper eye care. If you suspect you have an eye disease, such as diabetic retinopathy, see an optometrist or ophthalmologist. There are also vitamins and supplements available, such as vitamins a, c, and e and lutein, which may help prevent various diseases and maintain proper eye nutrition.
Resources on three of the most common eye diseases are below:
Macular degeneration breaks down the macula, the light-sensitive part of the retina. It is diagnosed as either dry (atrophic) or wet (exudative). The dry form is more common than the wet, with about 90% of AMD patients diagnosed with dry AMD. The wet form of the disease usually leads to more serious vision loss. Learn more here:
Glaucoma affects an estimated 3 million Americans, with 120,000 blind due to the condition. When intraocular pressure increases to dangerous levels, it damages the optic nerve. This can result in decreased peripheral vision and, eventually, blindness. There are two major types of glaucoma: chronic or primary open-angle glaucoma (POAG) and acute closed-angle glaucoma.

A cataract is a clouding of the eye's natural lens, which lies behind the iris and the pupil. The lens focuses light onto the retina, and also adjusts the eye's focus. The lens is mostly made of water and protein. As we age, some of the protein may clump together and start to cloud a small area of the lens. This is a cataract, and over time, it may grow larger and cloud more of the lens, making it harder to see. Learn more here:
