Authentic Ray-Ban Clubmaster prescription glasses purchased on Rakuten, with a power of -4.25. I kept these for special occasions, but my prescription has changed and they no longer fit. These have been stored for a long time. Prescription Information: R (Right Eye) SPH[ -4.25 ]D CYL[ +0.00 ]D AX[ 0 ]° PD[ 31.50 ]mm L (Left Eye) SPH[ -4.25 ]D CYL[ +0.00 ]D AX[ 0 ]° PD[ 31.50 ]mm The lenses are also Ray-Ban, so they have the Ray-Ban logo on them, which is not visible in your field of vision. I accidentally used the original case for another shipment, so a used Ray-Ban case will be included.
