UN radiations come from every direction. Some effects directly to our eye or some UV radiations reflect from ground, mirror and then comes to us. Many understand the link between ultraviolet (UV) radiation and skin cancer. But many are less aware of the connection between UV radiation and eye damage. Later kind of people take it forgranted, with increased levels of UV radiation reaching the Earth’s surface, it is important to take the necessary precautionary measures to protect eyes. Global warming is a major issue in Pakistan and eye diseases are its main side effects.
WHAT IS UV RAY?
The sun’s primary danger to us comes in the form of UV light or radiation. UV radiation is a component of solar radiation. Artificial sources like welding machines, tanning beds,x rays and lasers can also give off such radiations which are not only harmful to eye but also damages the whole body. UV radiations causes the mutation in normal cells and change them in neoplastic.
There are three types of UV radiation.
- UV-A and UV-B radiation can have adverse long- and short-term effects on the eyes and vision.
- UV-C is absorbed by the ozone layer and does not present any threat.
WHO ARE AT RISK?
Everyone (at any age. Including children) is at risk for eye damage from UV radiation that can lead to vision loss or skin cancer. Any factor that increases the amount of time you spend in the sun will increase your risk of UV radiation damage. Some activities that increases amount of time spend in sunlight are
- Skiing, mountain climbing, swimming, at the beach, for long hours
- use of sunlamp, tanning bed or booth
- live in the mountains or the US Sunbelt
- anyone who had cataract surgery (in one or both eyes)
- anyone with retinal disorder
- certain medicines, such as tetracycline, birth control pills, diuretics and tranquilizers (that increase the eye’s sensitivity to light and more susceptible to sunlight related eye disorders)
- If anyone is a welder, medical technologist or work in the manufacturing of electronic circuits.
HOW IT IS TREATED?
There are many treatment methods available for allergic conjunctivitis according to cause and severity
- Antitihistamine eye drops
- Oral antihistamine
- Mast cell stabilizer eyedrops
- .Antihistamine and mast cell stabilizer eyedrops
- NSAID eyedrops
- Treating allergic conjunctivitis at home involves a combination of prevention strategies, improve activities to eliminate the symptoms and reduce the risks.

Block out 99 to 100 percent of both UV-A and UV-B radiation and Screen out 75 to 90 percent of visible light. Such glasses have protective coatings and coverings that is actual a primary and safest method to avoid the UV radiations.
-If you spend a lot of time outdoors in bright sunlight, wrap around frames can provide additional protection from the harmful solar radiation.
