The theme for world Sight Day 2020 is “Hope In Sight”. It is a global event observed every second Thursday of October to raise awareness about blindness and vision impairment. It is to encourage people and government to participate in blindness prevention programmes and educate masses on the same. The first world sight day was observed in 2000, initiated by ‘SightFirstCampaign’ of Lions Club International Foundation. It now has been consolidated into VISION 2020, coordinated by International Agency for the Prevention of Blindness (IAPB) in association with the World Health Organisation.
IAPB members are directly involved in the delivery of eye care services across the world. They focus on building capacity, human resource development, in low-income countries.
- More than a billion people have sight issues merely because they don’t have access to glasses.
- Over 3 out of 4 of the world’s vision impairments are avoidable.
- About 65 per cent of people with visual impairments are above the age of 50.
- 90 per cent of visually impaired people live in low-income nations.
- Roughly around 19 million children are visually impaired; 12 million of which are the result of easily diagnosable and treatable refractive errors (myopia and hypermetropia).
- About 217 million people suffer from Moderate to Severe Vision Impairment (MSVI).
Factors Leading to Blindness
Reduced eyesight can be caused by several factors, including :
- Diseases like diabetes and trachoma, – Trauma to the eyes
- Conditions such as refractive error such as nearsightedness, farsightedness and astigmatism
- Age-related macular degeneration or glaucoma
- Diabetic retinopathy
Preventive Measures for Avoidable Blindness
- Get regular eye care. Early and accurate diagnosis may prevent you from a possibility of future blindness.
- Get to know your family history on vision problems.
- Keep your blood sugar levels in check to prevent diabetic retinopathy
- Keep your blood pressure under control to prevent glaucoma
- Smoking and excessive use of alcohol increases the risk of cataracts and other eye problems.
- Protect your eyes while using mobile or computer screens. Splashes of cold water and eye movement can help the tired eye muscles.
- Protect eyes from sunlight and extremely bright lights.
Vitamin A-Rich Diet For Good Eyesight
- Vitamin A is important for the eyesight. Vitamin A protects the surface of the eyes and cornea, and helps prevent age-related macular degeneration of the eyes.
- Vitamin A rich fruits – papaya, carrots, peach
- Vitamin A rich vegetables – spinach, fenugreek, bell peppers
- Dairy – Milk and cheese
