10 Best Foods for Healthy Eyes

Maintaining a healthy lifestyle can considerably reduce the risk of eye health problems. Failing eyesight isn’t necessarily as a result of aging or eye strain. The Age-Related Eye Disease Study (AREDS), published in 2001, discovered that certain nutrients such as vitamin C, vitamin E, copper, zinc, and beta carotene may all help to reduce the risk of decline in eye health as a result of age by 25 percent.

Other studies found that the intake of omega-3 fatty acids (including DHA), copper, lutein, and zeaxanthin are essential for eye health. Some studies have discovered that fish oil can reverse dry eye caused by spending too much time on a computer.
