I've used Zenni for years. They've got great selections of regular prescription frames but I'd like to see more bifocal frame options. I love how they recommend the lens best for your prescription and frame. Not to mention their prices are affordable. **It'd help if they'd turn the "try on" with photos back on.
Tip for consumers: make sure to check measurements of the frames you are wanting. My 1st order I didn't check them and my frames were way too big for me.
Products used: I purchased both regular lens and bifocal lens along with clip-on sunglasses for both pairs of glasses
