These lenses are made for the Ray-Ban 0840S MEGA WAYFARER in size 51. They are not universal lenses and should not be used for other Wayfarer models, even if the frame looks similar. The shape, bevel and Base 6 curve must match the frame precisely.

This lens has a 56 mm diameter and a Base 6 curve, both important for correct fit and optical alignment in the frame.

Polarized lens options are available only in the variants marked 57 – brown polarized and 58 – green polarized. Mirror lens finishes are available in 2K – red flash mirror and 93 – yellow flash mirror.
The MEGA WAYFARER frame is built to last. Replacing only the lenses lets you refresh your sunglasses for less than buying a new pair, while keeping the original frame and reducing waste.
