Don't know how to find a perfect size? Have a quick read of the following articles to know the most important and basic measurements of our sizes at VisoOne.
A frame that is too narrow will make your face look wider, while a frame that is too wide will make your face look narrower. Find a frame that is slightly wider than your face — no more than a finger width between the temple and your face. If you already have a glasses that fit, you can measure from screw to screw. This complete measurement would be your ideal frame width.
But please keep in mind that frames are various from one to another. This is a general idea to measure your ideal frames.
Temple (arm) length
This measurement does not vary as much as the others. The temple is typically 120mm to 150mm long, of which 135mm, 140mm, 145mm, and 150mm are the most common options. Measure the temple from each screw to its temple tip, including the bend that sits on your ear.
Measure the distance between your two lenses. If you have close-set eyes or want a narrow bridge, this number should be lower; if you have wide-set eyes or want a wide bridge, this number should be higher. The bridge should sit nicely above your nose. If your nose is higher on your face, an eyeglass style where the bridge is even with the frame’s brow line will look best; if your nose is situated a bit lower on your face, a frame with a lower bridge and curved brow line will better suit your features.
Measure the horizontal width of each lens at its widest point.It typically ranges from 40mm to 60mm. To determine which lens size is right for you, know that a small lens width is 50mm or less, medium is between 51mm and 54mm and large is any lens wider than 55mm.
To find lens height, measure the widest or longest parts of the lens.
