Check the fit (frame width and bridge size) to match your face, ensure solid UV protection (UV400), and choose durable materials. If you want glare reduction, consider polarized lenses.

Look at UV protection, polarization, lens tint and material, frame material and size, and any warranty or brand reputation.

For driving or bright days, polarized or darker tints help. For versatile use, consider the lens category (1–3) and options like mirrored coatings or photochromic lenses.

Some styles offer prescription lenses or compatible clip-ons; check if the model supports Rx options or if you can add prescription lenses through your optician.
