I’ve been very happy with my eyewear from Roka.com. Their sunglasses run $125-$150 and are built on the same frames as their prescription eyeglasses. Roka have have a “home try on” program where they send you four frames of your choice (with blank lenses) to try on for 7 days (you pay shipping). After you figure out what works well, you can place the order for the actual pair you will keep. Their website also has detailed dimensions for most of their frames.
FWIW, their prescription eyewear has been the best I’ve ever owned (and I’ve worn glasses my whole life). They also recently started offering bifocal and progressive lenses.
