Start with fit and comfort: check frame size (small/medium/large) and the bridge width, then choose a shape that flatters your face. Make sure the material and weight feel comfortable for all-day wear.

Key decisions are frame material and durability, size and fit, prescription compatibility, and lens options (lens type and coatings). Also consider UV protection and whether blue-light filtering is desired.

For use-cases or feature preferences, decide if you need anti-reflective or scratch-resistant coatings, blue-light filtering for screens, or progressive lenses. If you wear them all day, prioritize lightweight, comfortable nose pads and balanced weight.

For a versatile option, look for a mid-weight frame with a neutral blue that matches most outfits, plus a universal fit (medium size, comfortable bridge). Ensure prescription compatibility and choose practical lens features like anti-reflective coating.
