Look for strong UV protection (aim for 100% UV) and a lens type that fits your needs (polarized for glare reduction or specialty lenses). Also ensure the frame fits your face and stays comfortable for extended wear.

Prioritize UV protection, lens type (polarized vs non-polarized) and lens tint, then check frame fit, coverage, and material for durability and comfort.

Consider your use-case—daily wear vs. outdoor activities or driving—then review frame weight, durability of materials, and how the lenses handle glare and scratches.

For driving, prioritize glare reduction with polarized lenses and a neutral tint; for all-day outdoor use, opt for robust frames, reliable UV protection, and a comfortable fit.
