Find Your Fit

This guide will help you find the best fitting frames and navigate the smart glasses with ease.

Already Using a Pair of Glasses? Check Your Measurements

If you already have a pair of glasses that fit you well, compare those measurements to determine if the glasses will fit you. Make sure to compare optical to optical glasses and sunglasses to sunglasses. Most glasses have the lens, bridge, and temple measurements engraved on the inside of the temple arm.

Don't Compare the Fit of Eyeglasses and Sunglasses

We recommend not comparing the measurement of sunglasses with your prescription or blue light filtering glasses in order to ensure the best fit. Some people prefer to wear oversized sunglasses.

Size Guide

Echo Frames Smart Glasses are a standard fit (best suited for higher nose bridges) and come in a range of sizes. Choose the pair that corresponds with your own face width: narrow, medium or wide. You can also take your frames to your optician to be adjusted for optimal fit.

Different Face Sizes

Shop Narrow

The narrow fit is best for slender faces. Try a narrow fit if glasses often slip down your face.
