Think about how you’ll use them (daily wear vs outdoor activity), the level of UV protection, and the lens type (polarized, photochromic, or standard).

Look at lens protection (UV), lens type (polarized or photochromic), frame size/fit, and comfort features such as nose pads and temple grip.

Consider your activity and environment (cycling, hiking, driving), weather conditions, and whether you prefer a wrap-around frame or a flatter profile for a specific use case.

For bright sun sports, prioritize glare reduction and a secure fit; if you wear prescription glasses, check compatibility or available prescription lens options.
