Yes these exist. CADDIS sunglass readers come with a backside bi-focal, high grade polarized lens and availability in our best-selling styles. Consider it a two-in-one solution (or a stop-stacking-your-glasses-on-your-head intervention). Bottom line: If you need readers, you need sun readers.
CADDIS sunglass readers have a “backside” bifocal so you can see through two lens areas - one close up, one at a distance. The bifocal on the back side means it's less noticeable from the front. The sun shade lens protects your eyes from harmful UV light and reduces glare while reading.
