Look for Complete UV Protection

When buying sunglasses, it is important that you get full protection against the UV rays. Your sunglasses should do the following:

  • Have lenses that block 100% of UV rays
  • Have lenses that meet the ANSI Z80.3 requirement that is the standard set by the American government.
  • Provide UV 400 protection that blocks out even the smallest UV rays.

The harmful rays from the sun can damage your eyelids, cornea, and the lens. It can also lead to macular degeneration and cataracts, which is why your sunglasses should offer 100% protection against both UVA and UVB rays. Do not buy sunglasses that donโ€™t provide details about the UV protection.

  • Wear sunglasses during winters because snow reflects almost 80% of the UV rays.
