Role of Nutrition in Eye Health

Good nutrition is essential for maintaining eye health. Vitamins such as Vitamin A, C, and E and minerals like zinc contribute to the retina’s health and may help ward off conditions such as AMD and cataracts. Antioxidants in various fruits and vegetables can help protect the eyes from oxidative stress. The omega-3 fatty acids in fish support eye health, potentially reducing the risk of dry eye and glaucoma.

Common Eye Diseases and Conditions

Eye diseases can significantly affect vision. Cataracts, which are characterized by clouding of the lens, are a common cause of vision impairment. Glaucoma is another serious condition that can lead to vision loss due to increased pressure within the eye damaging the optic nerve. Additionally, dry eye conditions affect millions and can lead to discomfort and blurred vision. Age-related macular degeneration (AMD) is one of the leading causes of vision loss in older adults, characterized by damage to the macula, the central part of the retina.

The Impact of Age on Eyesight

As people age, their risk of developing eye diseases such as AMD and cataracts increases. After 60, one’s vision often begins to decline, and the need for regular eye examinations becomes more crucial. Nutrients and vitamins that support eye health can become increasingly vital with age to help maintain as much vision quality as possible.

Key Supplements for Eyesight

Numerous supplements can support eye health and potentially protect vision. The following important nutrients have been associated with maintaining good eyesight and reducing the risk of certain eye diseases.
