Both of us use a fairly complex prescription that involves progressive lenses with either astigmatism or widely varying corrections for each eye. In addition, Jim is — of course — male, and I’m a female. Because SportRx has its own lab and because the opticians who run it are themselves outdoors enthusiasts, they specialize in sunglass styles like the wraps we use on the water. Wraps can be fairly tricky because, as their name suggests, they wrap or bend around the face for full coverage, which better blocks glare. When you bend a prescription lens, it can start to warp the wearer’s perspective.
