Tanning beds emit high levels of UVA and UVB rays, which can be harmful to the eyes if proper eye protection is not used. Prolonged exposure to these rays can increase the risk of developing photokeratitis and other eye conditions.
Welding arcs
Welding arcs produce intense UV radiation that can cause severe damage to the eyes if proper safety measures are not taken. Welders are at a high risk of developing photokeratitis if they do not wear appropriate eye protection, such as welding helmets with UV filters.
Reflection of UV rays
Another significant cause of photokeratitis is the reflection of UV rays from various surfaces, such as water, snow, and sand. These surfaces have high reflective properties and can amplify the intensity of UV radiation.
Water
When sunlight hits the water surface, it reflects a significant amount of UV rays. This reflection can occur in swimming pools, lakes, or oceans. It is important to wear UV-protective sunglasses while engaging in water activities to minimize the risk of photokeratitis.
Snow
Snow is highly reflective and can reflect up to 80% of UV radiation. Skiers, snowboarders, and mountaineers are particularly at risk of developing photokeratitis due to the high altitude and the reflective nature of snow. Wearing goggles or sunglasses with UV protection is essential to prevent eye damage.
Sand
Beachgoers should also be cautious as sand can reflect UV rays, especially in sunny environments. Wearing sunglasses and using sunscreen on the face and eyelids can provide added protection against photokeratitis.
In conclusion, photokeratitis can be caused by various factors, including prolonged exposure to UV radiation from the sun, artificial sources of UV radiation, and the reflection of UV rays from water, snow, and sand. Understanding these causes is crucial in taking proactive measures to protect our eyes and prevent the development of photokeratitis.
