☀️ What UV Protection Actually Means in Sunglasses
UV protection in sunglasses refers to the ability of the lenses to block ultraviolet (UV) rays from the sun — invisible radiation that can harm your eyes over time.
There are two main types of UV rays that matter:
-
UVA rays: Long-wave rays that penetrate deep and cause aging-related damage to your eyes.
-
UVB rays: Short-wave rays that are more intense and cause sunburn-like damage, especially to the cornea.
Your eyes, like your skin, are vulnerable to harmful ultraviolet (UV) rays. Long-term exposure to UV radiation can lead to serious eye conditions such as:
-
Cataracts
-
Macular degeneration
-
Photokeratitis (sunburned eyes)
-
Pterygium (surfer’s eye)
High-quality sunglasses block 99% to 100% of UVA and UVB rays, preserving not just your vision but your overall eye health.
💡 Always look for labels that mention:
✔ 100% UV Protection
✔ UV400 rated lenses
✔ Polarized (optional for glare protection)
