Photokeratitis: A Painful Eye Condition
Photokeratitis, also known as snow blindness, is a condition that affects the cornea of the eye. It is caused by overexposure to UV rays from the sun or artificial sources like tanning beds or welding arcs. The condition is most common in skiers, snowboarders, and mountaineers who spend long hours in high-altitude environments where the intensity of UV radiation is higher.
Symptoms of photokeratitis include pain, redness, sensitivity to light, tearing, and blurred vision. In severe cases, the cornea may become cloudy, leading to temporary vision loss. The symptoms usually appear several hours after exposure and can last for several days.
Here are some tips on how to prevent photokeratitis:
- Wear protective eyewear that blocks 100% of UV rays.
- Avoid direct exposure to the sun during peak hours (10 am to 4 pm).
- Wear a wide-brimmed hat or cap to shade your eyes.
- Use sunscreen on your face and eyelids to prevent sunburn.
- Take breaks indoors or in shaded areas to give your eyes a rest.
If you experience symptoms of photokeratitis, it is important to seek medical attention. Treatment may include prescription eye drops, pain relievers, and other medications to reduce inflammation and promote healing. In severe cases, surgery may be necessary to repair damage to the cornea.
Don't let photokeratitis ruin your outdoor fun. Take the necessary precautions to protect your eyes from the damaging effects of UV radiation.
