It is alarming to know that an estimated 253 million people live with vision impairment worldwide, including 36 million who are blind and 217 million who have moderate to severe vision impairment, according to the World Health Organization (WHO). Poor nutrition is a significant factor contributing to vision problems, especially as people age. Both children and older adults can experience eyesight issues due to inadequate nutrition. Ensuring a diet rich in essential vitamins and nutrients can help maintain eye health and reduce the risk of vision impairment. This article explores the best foods and vitamins for eye health.
The Importance of Nutrition for Eye Health
Proper nutrition is crucial for maintaining good vision and eye health. Vitamins and minerals found in various foods play essential roles in protecting the eyes from damage, reducing inflammation, and preventing age-related eye diseases.
Best Vitamins for Eye Health
Beta-Carotene
