Frame width is the primary way we determine fit. It’s the horizontal diameter of the entire frame width.
*Note that you won’t find this number on your glasses.
Other Technical measurements
Like most brands of glasses, the measurements of eyebobs glasses can be found on the inside of the temple arm. The first number indicates the lens width (46mm) and the second number is the bridge (23mm). If you already have a pair of glasses you like, you can use those measurements as a reference.

Frequently Asked Questions
Why should I choose eyebobs over drugstore readers or designer frames?
eyebobs was founded to fill the gap between cheap drugstore readers and overpriced designer frames. We painstakingly select the very best materials – like luxury acetate, comfortable spring hinges, and best-in-class, optical-quality lenses – because we won't take "meh" for an answer. If your life hasn't been changed by a pair of eyebobs, our job isn't done yet.
Do your lenses come with smudge or scratch-resistant coatings?
Yep – every lens we offer except traditional readers comes with anti-reflective coating to cut glare (for you and anyone looking at you). And all of our lenses, no exceptions, are scratch-resistant.
Are eyebobs lenses UV protected?
All of our tinted (outdoor) lenses and prescription lenses come with 100% UV protection, so you don't have to worry about the sun's rays doing damage to your eyes.
What diopter strengths are available?
Traditional readers range from 0.00 to +4.00, while our progressive readers cover +1.25 to +3.50. Not sure what strength you need? Take our Reader Strength Test to find out.
Can I add blue light blocking to my lenses?
Absolutely – blue light blocking can be added to readers or prescription lenses for $40. It's designed to block HEV light (415–455 nanometers) and may help ease dry eyes, headaches, and blurred vision from screen time.
