Remember when wearing glasses used to be viewed as less than desirable? Somehow, needing some help to see clearly was considered “uncool.” How weird was that? Today, people who don’t even need a prescription are wearing clear frames as a fashion statement. Oh, how times have changed — and we are so glad they did! Prescription glasses are more than just a way to have stellar vision. Your glasses are a part of who you are, and therefore must be of the highest quality. After all, they’re on your face! Size, shape, and comfort are all factors that are tough to shop for online. So our team of expert opticians did the research for you. Keep reading our Ray-Ban Eyeglasses Size Guide to find the best prescription glasses for your face shape and size.

What Size Ray-Bans Should I Get?
It's not fun to buy a great looking pair of glasses, only to find them sliding down your nose, or pinching your temples. You don't get the full benefits of quality eyewear if your prescription glasses don't fit properly. So before we get into our breakdown of the best Ray-Ban specs by size, let's quickly chat about how we measure these frames.
If you already know about SFW — welcome back! Feel free to jump ahead to our list of eyeglasses. And for those who are new to the SFW, it's great to meet you! SFW is a standardized eyewear measurement which stands for "SportRx Frame Width." It is an easy way to measure any pair of glasses. To learn more about SFW and how to measure your own, watch our video, What Is SFW?
Ray-Ban Eyeglasses Size Guide
Once you know your SFW, you'll have a better idea of what size category you fit into best. Here's a breakdown of our sizing guide:
Men
- SFW of 118–129 = XS/S
- SFW of 130–135 = M
- SFW of 136–148 = L/XL
Women
- SFW of 114–124 = XS/S
