Understanding Exposure Keratoconjunctivitis
Exposure keratoconjunctivitis is a type of eye condition that is caused by prolonged exposure to ultraviolet (UV) radiation from the sun. It is also known as “snow blindness” since it is commonly seen in people who spend a lot of time in high-altitude snowy environments without proper eye protection.
When the eyes are exposed to excessive amounts of UV radiation, it can cause a painful inflammation of the conjunctiva and the cornea. Symptoms of exposure keratoconjunctivitis include redness, tearing, blurred vision, and sensitivity to light. In severe cases, it can lead to temporary vision loss.
Preventing Exposure Keratoconjunctivitis
Preventing exposure keratoconjunctivitis is relatively easy. The most important thing is to protect your eyes from UV radiation. Wearing sunglasses that block 100% of UV rays is the best way to do this. It is also recommended to wear a wide-brimmed hat or a cap with a visor to provide additional protection from the sun.
If you are planning to spend extended periods of time in high-altitude snowy environments, it is essential to wear protective goggles that are designed to block UV radiation. These goggles are typically made with polycarbonate lenses that are impact-resistant and can withstand extreme temperatures.
Treating Exposure Keratoconjunctivitis
If you suspect that you have exposure keratoconjunctivitis, it is essential to seek medical attention immediately. Your doctor will likely prescribe antibiotic eye drops to prevent infection and reduce inflammation.
In the meantime, you can take steps to alleviate your symptoms. Applying a cool compress to your eyes can help reduce swelling and ease pain. You should also avoid wearing contact lenses until your eyes have fully healed.
Conclusion
- Exposure keratoconjunctivitis is a painful eye condition caused by prolonged exposure to UV radiation from the sun.
- Prevention is key, and wearing sunglasses that block 100% of UV rays and protective goggles in high-altitude snowy environments is essential.
- If you suspect you have exposure keratoconjunctivitis, seek medical attention immediately.
By taking simple precautions to protect your eyes, you can prevent exposure keratoconjunctivitis and enjoy all the benefits of spending time outside in the sun.
