Start with how they will fit your current frames: confirm the clip-on mechanism fits your temple style and lens width. Choose true polarised lenses with 100% UV protection and a neutral tint, and check frame material and comfort.

Compare lens polarisation quality and UV protection, clip-on compatibility with your frames, and the overall fit (frame size, bridge width, and weight) to ensure comfort across wear.

For driving or glare-prone settings, prioritize strong polarization and a suitable tint; for general outdoor use, look for durability and a comfortable fit.

Clip-ons are designed to attach to most compatible frames; check the clip width and mounting style, and ensure the lenses provide polarisation and UV protection that suit your prescriptions and daily routine.
