How to Measure Frame Size

When you used to pay expensive prices to buy glasses from the local optical store, you could try them on to see how they fit. Buying glasses online is uncharted territory for many. 

But, there's no need to worry! It's very easy to find your frame measurements to ensure you're getting the right fit. And you're going to save a bundle by ordering glasses from Olet Optical.


1. About the frame size you should know.



2. How to find out your glasses measurements?



1)、Primary Way Measurements - Frame Width


Frame width is the entire horizontal front of the frame, from the furthest extended point on either side. (Note: You will not find this number on your glasses.)     





2)、Other Way Measurements


If you already have eyeglasses, find the measurements on the inside of the temple arm or demo lens such as 52-17-140 (means lens width is 52mm, bridge is 17mm, temple length is 140mm ), you can compare it to the measurements. However, we still recommend measuring the Frame Width to choose the right eyeglasses frame.





3)、Tips for Choosing Comfortable Lenses
(1) For bifocal or progressive prescriptions: the lens height of frame must be 35mm or greater.
(2) If SPH on your prescription is +/-6.00 or greater, choose a frame with lens width lower than 50mm, and choose high-index lens.
