☀️ The Impact of UV Rays on Eyes
Ultraviolet (UV) rays include UVA, UVB, and UVC. UVC is filtered by the atmosphere, but UVA and UVB reach the Earth and can harm your eyes.
Short-term effects: Photokeratitis (“snow blindness”), pain, and excessive tearing.
Long-term effects: Cataracts, macular degeneration, pterygium, and premature aging of the eyes.
Even on cloudy days or during winter, UV rays are still present and can intensify through reflection from snow or water.

Sunglasses are not just fashion accessories; their true function is:
