Start by considering how you'll use them and your face fit. Look for a frame size and shape that covers your eyes comfortably and has secure nose pads.

Look at lens category (how dark they are), UV protection, lens technology (adaptive/photochromic or polarization), frame size and fit, and overall durability.

Think about wrap coverage, grip, and whether the lenses suit your sport or daily use. For cycling or running, a secure wrap and non-slip nose pads help; for casual wear, lighter frames may be more comfortable.

Some Julbo frames support prescription inserts; check compatibility with the exact model or consider clip-ons or RX-ready options offered by the retailer.
