World Sight Day (WSD) is an annual day of awareness held on the second Thursday of October, to focus global attention on blindness and vision impairment. World Sight Day 2017 is on 12 October 2017. This year, the ‘Call to Action‘ for World Sight Day is: Make Vision Count
Approximately 285 million people worldwide live with low vision and blindness. Of these, 39 million people are blind and 246 million have moderate or severe visual impairment. 90% of blind people live in low-income countries, yet 80% of visual impairment is avoidable – i.e. readily treatable and/or preventable. An estimated 19 million children are visually impaired. About 65 % of all people who are visually impaired are aged 50 and older, while this age group comprises only 20% of the world’s population.
3 Tips for Better Eyesight
Eat eye-healthy foods
A nutritious diet has benefits for all types of health conditions, but some foods are particularly beneficial for eyes. Fatty fish such as tuna, herring or sardines are rich in omega-3 which nourish the cell membranes of nerve cells, including the retina, and help prevent the onset of eye diseases linked to aging. Including fruits and vegetables in your diet can also boost eye health thanks to being rich in antioxidants and vitamins A and C, which help protect the cornea and lens of the eye, prevent cataracts, and prevent eye fatigue.
Smoking increases the risk of cataracts, macular degeneration and damage to your optic nerve. It also helps maintain a healthy weight which reduces the risk of diabetes, which can also cause eye problems.
Reduce screen time
According to a report by The Vision Council, 93.3 percent of Americans spend two or more hours every day on digital devices for work or play, which is resulting in “digital eye strain,” a condition which causes “temporary physical discomfort” after two or more hours in front of a digital screen.
To avoid the condition, which can result in redness, irritation, dry eyes, blurred vision, eye fatigue, back and neck pain and headaches, experts recommend taking regular screen breaks, and also adjusting things like text size, posture, and computer setup.
