Excessive exposure of children to video games, mobiles, computers, televisions has been adversely impacting their eye health. Moreover, India has become the diabetes capital of the world with as many as 50 million people suffering from type-2 diabetes.
The National Programme for Control of Blindness (NPCB), the Central government has been making constant efforts since 1976 to reduce the prevalence of blindness in India.
It has set the goal of reducing the prevalence of blindness to 0.3% by the year 2020. As per the NPCB data, cataract continues to be one of the leading causes of blindness in India. Nearly 63% of people are blind due to cataract. around 20% of people are blind due to refractive error. Another major area of concern is ‘Diabetic Retinopathy’. It is the most well-known ocular complication of diabetes and the leading cause of blindness among people between 20-64 years.
The sublime ethos of helping a vision impaired person to gain eyesight through voluntary eye donation must be inculcated among the young children in the schools. Mass media can play an important role in popularising eye donation.
The vitamins, minerals and other nutrients have been shown to be essential for good vision and may protect eyes from sight-robbing conditions and diseases.
A healthy diet for eyes should include plenty of colorful fruits and vegetables.

Food sources: Seafood (shrimp, crab, salmon, halibut), Brazil nuts, enriched noodles, brown rice.
RDA: 55 mcg for teens and adults (60 mcg for women during pregnancy and 70 mcg when breast-feeding).
Eye benefits of vitamin A: May protect against night blindness and dry eyes.

RDA: 3,000 IU for men; 2,333 IU for women (2,567 IU during pregnancy and 4,333 IU when breast-feeding).

RDA: None, but the American Academy of Pediatrics recommends 400 IU per day for infants, children and adolescents, and many experts recommend higher daily intakes for adults.
The best source of vitamin D is exposure to sunlight. Ultraviolet radiation from the sun stimulates production of vitamin D in human skin, and just a few minutes of exposure to sunlight each day (without sunscreen) will insure your body is producing adequate amounts of vitamin D.
Eye benefits of vitamin E: When combined with carotenoids and vitamin C, may reduce the risk of advanced AMD.
Food sources: Almonds, sunflower seeds, hazelnuts.
RDA: 15 mg for teens and adults (15 mg for women during pregnancy and 19 mg when breast-feeding).
Eye benefits of zinc: Helps vitamin A reduce the risk of night blindness; may play a role in reducing risk of advanced AMD.
