Ray Ban 2132 size 52 are smaller than
Ray Ban 4150 size 50. The frame rim of
RB 2132 is more narrow, that's why it features a smaller fit even though the lenses are 2 mm wider.
Unfortunately, there is no official comparison information from
Ray Ban. I just have a few pairs of
Ray-Ban Wayfarer sunglasses in front of me, take the measurements, and let a few people try them on, compare and share my thoughts. I rely on the feedback from my customers as well. My
Ray Ban representative also agrees with me

So, there are good chances that I'm right.
If you buy this frame, please post a few lines and tell us if you do like or not how it fits. Everybody is different, there is never 100% guarantee that the
sunglasses you have never tried before will work. But we have 30 days no restocking fee return policy, so you can always return them or exchange for a different model. You will be short only off the postage fee to send the
sunglasses back to us. On the bright side, we do not have that many returns & exchanges, so for the majority of our customers that works!
