Which is why I was super pumped when DJ introduced me to Zenni Optical a few years ago. These guys have prescription glasses starting from $8US including the frames and the lenses. Shipping is a flat fee, and they have a mammoth range of glasses.
I'm thinking that this week I'll get my prescription updated and then order myself these! Yuss!
Fingers crossed they'll suit me and fit my ginormous head because this style is available in white, red, and tortoiseshell. Gotta catch 'em all!
