Stay Safe Under the Sun: Understanding and Using the UV Index

What Is the UV Index?

The UV Index is a standardized scale that measures the strength of ultraviolet (UV) radiation from the sun. It ranges from 0 (low risk) to 11+ (extreme risk) and is updated daily based on weather and sun intensity. Monitoring the UV Index helps you plan outdoor activities and protect your eyes effectively.

Why UV Protection Matters for Your Eyes

• Prevents cataracts and other eye diseases caused by UV damage
• Reduces the risk of macular degeneration
• Prevents photokeratitis, a painful sunburn of the cornea
• Protects sensitive skin around the eyes from sun damage

How to Use the UV Index

• Low (0-2): Minimal protection needed, but sunglasses can still be worn for comfort.
• Moderate (3-5): Wear sunglasses with 100% UV protection and a hat if outdoors for long periods.
• High (6-7): Use polarized sunglasses, a wide-brim hat, and seek shade during peak sun hours.
• Very High (8-10): Take extra precautions including UV-blocking eyewear and limited sun exposure.
• Extreme (11+): Avoid direct sun exposure and protect eyes and skin with sunglasses and protective clothing.
