Think about where you’ll wear them and what you’ll do in them; then assess fit, coverage, and basic lens features like tint and protection to match conditions.

Lens quality and tint, polarization, wraparound design for coverage, frame fit and grip, and whether lenses can be swapped for changing conditions.

For cycling or running, prioritize light weight and a snug wrap with good grip; for water sports, polarization helps with glare; if you wear a helmet, check compatibility.

Consider lens tint and the option for interchangeable or photochromic lenses, so you can adapt from bright sun to shaded areas without changing glasses.
