Start with a comfortable fit and good coverage, then check lens quality and UV protection (look for 100% UVA/UVB). Consider frame material and temple length for all‑day wear.

Key attributes include lens type (polarized or not), UV protection, frame size and shape, and how the lenses affect glare and color perception for your activities.

For sports, look for wraparound style, durable materials, and non-slip features; for driving or outdoor work, consider lens tint and contrast to enhance visibility and reduce glare.

Choose youth or smaller-frame options to ensure proper coverage and a secure fit; check measurements and temple width to match a smaller face for comfort during wear.
