Hi Jeremy,Ray Ban RX 5121
is getting more and more popular.
I took a few pairs from stock to take the measurements. Here is what I got:RX5121
50 mm Lens Size - 47 mm horizontal / 40 mm vertical / 50 mm effective diameter (the one that we refer on the site to as a lens size) / 22 mm distance between the lenses. In general I would say it's a large fit.RX5121
47 mm Lens Size - 45 mm horizontal / 38 mm vertical / 47 mm effective diameter / 22 mm distance between the lenses. In general I would say it's a medium fit.
If you are ready to purchase these eyeglasses
, you can either place an order for RX 5121 frames
with Demo lenses and take them to your local optician to order Rx lenses from him or place an order for RX5121 eyeglasses
with Rx lenses installed. We usually beat local stores in pricing.
But that's definitely a personal choice. For your convenience I provided the links below:http://www.opticsplanet.com/ray-ban-eye ... x5121.html
