-
Polarization reduces glare from reflective surfaces (water, snow, roads).
-
UV protection blocks harmful UVA & UVB rays that can damage your eyes and lead to cataracts or macular degeneration.
A pair of sunglasses can be polarized without UV protection—and that would be dangerous because your pupils dilate behind dark lenses, letting in more harmful UV rays.
✅ The safest option:
Look for Polarized + UV400 protection (blocks 99-100% of UVA & UVB).
Summary:
-
Polarized ≠ UV protection
-
Always check for UV400 or 100% UV protection even if the glasses are polarized.
