Key Facts
• Prolonged heatwave raises concerns about UV-related eye damage, not just heatstroke.
• Dr. Shunji Yokokura identifies three major UV-related eye conditions:
1. Corneal inflammation causing redness and pain.
2. Pterygium, where white tissue invades the cornea, reducing vision.
3. Cataracts, caused by long-term UV exposure, clouding the lens and impairing vision.
• UV exposure is a cataract risk factor, with higher rates in southern regions.
• Outdoor workers are more prone to pterygium and need extra precautions.
• Sunglasses are the most effective UV protection, with UV-blocking contact lenses as an alternative.
• Wide-brimmed hats and umbrellas enhance protection; men are increasingly using umbrellas.
• Dark sunglasses without UV protection can worsen exposure by dilating pupils.
• Police officers now wear sunglasses on duty, but children rarely use them.
• Dr. Yokokura advocates for a society where children can wear sunglasses in daily life.
Summary
As heatwaves persist, experts warn of the dangers of UV-related eye damage alongside heatstroke. Dr. Shunji Yokokura highlights three key conditions caused by UV exposure: corneal inflammation, pterygium, and cataracts. Southern regions and outdoor workers face higher risks. Sunglasses, especially those with UV-blocking features, are the most effective protection, complemented by wide-brimmed hats and umbrellas. However, dark sunglasses without UV protection can increase exposure. While police officers now wear sunglasses on duty, children rarely use them. Dr. Yokokura emphasizes the need for societal acceptance of sunglasses for children in daily activities to safeguard their eye health.
