Meet our Biff prescription glasses, or the frame formerly known as "Butch." These iconic frames come in small or wide sizes, so scores of heads can see what it means to "Biff it." Spoiler alert: it's a good thing.
Crafted with high-tech polycarbonate lenses, our Biff glasses are as close to shatter-proof as they come, ensuring durability and longevity. The anti-reflective coating on the lenses helps to eliminate glare, providing clear vision whether you're browsing the aisles of a bookstore or squabbling over the latest fashion trends.
90-Day Returns. A chinchilla can make a baby in 90 days. We figure that's plenty of time for you to decide if you want to keep your glasses.
Items in the Sale Collection are final sale — no returns or exchanges.

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.
