Photokeratitis, unspecified eye: Causes, Symptoms, and Prevention
Photokeratitis, also known as ultraviolet (UV) keratitis, is a condition that affects the cornea, the transparent layer covering the front of the eye. It occurs when the cornea is exposed to excessive amounts of UV radiation, usually from the sun or artificial sources like tanning beds.
Commonly referred to as "snow blindness" or "welder's flash," photokeratitis can cause significant discomfort and temporary vision loss. While it typically resolves on its own within a few days, prevention is key to avoiding this painful condition.
Causes
Photokeratitis can occur when the eyes are exposed to intense UV radiation without proper protection. Activities such as skiing, snowboarding, sunbathing, or spending time on the beach without sunglasses can increase the risk of developing this condition. Additionally, certain occupations, such as welding or working with lasers, may also expose individuals to high levels of UV radiation.
Symptoms
- Eye pain: Photokeratitis often causes a sharp, stinging pain in the eyes.
- Tearing and redness: The eyes may become watery and appear bloodshot.
- Blurred vision: Vision may become blurry or hazy.
- Sensitivity to light: Bright lights, including sunlight or indoor lighting, can cause discomfort.
- Gritty or foreign body sensation: It may feel like something is stuck in the eye.
If you experience any of these symptoms after prolonged sun exposure or exposure to intense UV radiation, it is important to seek medical attention to confirm the diagnosis.
Prevention
To prevent photokeratitis, it is essential to take appropriate measures to protect your eyes from UV radiation. Here are some preventive measures you can follow:
- Wear sunglasses: Choose sunglasses that offer 100% UV protection. Look for labels indicating that they block both UVA and UVB rays.
- Use a wide-brimmed hat: Wearing a hat with a wide brim can provide additional shade and protect your eyes from direct sunlight.
- Stay in the shade: When the sun's rays are strongest, typically between 10 a.m. and 4 p.m., try to stay indoors or seek shade.
- Protective eyewear: If you work in an occupation that involves exposure to intense UV radiation, wear appropriate protective eyewear to shield your eyes.
- Be cautious around reflective surfaces: Snow, sand, water, and other reflective surfaces can intensify UV exposure, so take extra
