Begin by considering your face shape and fit, then decide on lens options (UV protection and polarization) and your preferred frame style.

Look at frame size and shape, lens type and UV protection, and frame material/weight, along with your budget.

Consider activities (driving, outdoor use, formal wear), your desired tint, and whether you need prescription lenses or easy upgrades.

If you have a smaller face, look for narrower frames; for glare reduction, choose polarized lenses with high UV protection; if you need prescription lenses, confirm compatibility with your optician.
