Two eye sizes are sold for the Ray-Ban RB2140 Wayfarer — 50mm and 54mm — both built for the square plastic front and 150mm plastic arms of this unisex frame. Color-wise the aftermarket range runs the full set: grey, brown, and green G15 solids, gradient and mirror finishes, a photochromic grey, and a clear AR option for anyone wearing the Wayfarer over prescription lenses.

The Wayfarer's flat brow line is why mirror coatings read so cleanly on this shape — a flat lens reflects evenly, where a curved wraparound would distort the reflection at the edges. If you're torn between a mirror and a plain gradient, the flatter the frame front, the more a mirror finish pays off visually, and since the frame only comes in two sizes, tint really is the main decision once you've confirmed 50mm or 54mm against your current lens.

Frequently asked questions

Are these genuine Ray-Ban or Oakley lenses?

No — these are aftermarket lenses, independently made to match the 50mm dimensions of the Ray-Ban 2140. They aren't produced or endorsed by Ray-Ban; they're engineered purely to fit that frame correctly.

How hard is it to install replacement lenses myself?

Most Square frames use a simple press-fit: flex the frame slightly, seat one edge of the 50mm lens into the groove, then work your thumb around the rim until it clicks into place — no tools needed.

What if the lenses I order don't actually fit my frame?

Every pair is matched to a specific model, in this case the 2140, so mis-fits are uncommon, but if the lenses don't seat properly you can return them within 14 days for a full refund, no questions asked.

What's the warranty if a lens pops out or discolors after a few months?

All lenses are independently made and carry a 3-year warranty against manufacturing defects — if a 50mm lens fails to seat correctly or the coating degrades on its own rather than from an impact, we'll replace it free.
