Summer is a great time for outdoor fun, but too much sun can harm your eyes. One condition to be aware of is corneal sunburn, also known as photokeratitis. This occurs when your eyes are exposed to excessive UV light, similar to getting a sunburn on your skin.
What is Corneal Sunburn (Photokeratitis)?
Corneal sunburn, or photokeratitis, is an eye condition caused by overexposure to ultraviolet (UV) rays. The cornea, the clear front part of your eye, gets damaged from too much sunlight. Just like your skin can get sunburned from too much sun, your cornea can also suffer from too much UV exposure, leading to pain and discomfort.
Symptoms:
Redness in the eyes
Severe eye pain and discomfort
Tearing and swelling
Blurred vision
Sensitivity to light
A gritty feeling, as if there's sand in the eye
Diagnosis:
An eye doctor can diagnose photokeratitis through a comprehensive eye exam. They may use fluorescein dye, which helps highlight damage on the cornea.
Short-Term and Long-Term Effects:
Short-Term Effects:
Pain and Discomfort: Severe pain and discomfort can affect daily activities, making it difficult to focus on work or enjoy outdoor activities.
Temporary Vision Problems: Blurred vision and light sensitivity can hinder everyday tasks such as reading, driving, and using digital devices.
Eye Redness and Swelling: These symptoms can cause cosmetic concerns and self-consciousness.
Long-Term Effects:
Chronic Dry Eye: Repeated exposure to UV rays can lead to chronic dry eye, causing ongoing discomfort and the need for regular use of lubricating drops.
Cataracts: Prolonged UV exposure increases the risk of developing cataracts, which can impair vision and may require surgical intervention.
Macular Degeneration: UV damage can contribute to age-related macular degeneration (AMD), a serious condition that affects central vision and can significantly impact quality of life.
Lifestyle Impact: Long-term eye health issues can affect your ability to enjoy outdoor activities, lead to increased medical expenses, and decrease overall quality of life.
Treatment:
Rest: Avoid bright light and rest your eyes.
Cool Compresses: Apply cool compresses to relieve discomfort.
Artificial Tears: Use lubricating eye drops to keep your eyes moist.
Pain Relievers: Over-the-counter pain medication can help manage pain.
Avoid Contact Lenses: Do not wear contact lenses until your eyes have fully healed.
Prevention:
Wear Sunglasses: Use sunglasses that provide 100% UV protection.
Wide-Brimmed Hats: Wear hats to shield your eyes from direct sunlight.
Seek Shade: Avoid direct sun exposure, especially between 10 AM and 4 PM.
Protective Eyewear: In windy or sandy environments, wear protective eyewear to prevent particles from irritating your eyes.
Caution:
Untreated photokeratitis can lead to serious eye conditions like cataracts or macular degeneration, which can affect your vision over time. It's essential to protect your eyes and seek prompt treatment if you experience symptoms.
