Rectangle Frame Glasses

To find the best fit for your glasses, first you should look for the perfect eye size (width). Easy example is given below.

• Lens width
  Just look at the arm of your frame. You will find there number written in above pattern. First one is eye width.
• Lets say in your current frame (Or old frame which you have currently)  eye width is 52mm. But you like any frame on SEAYE which do not have size 52mm. In this case you do not need to worry. You can choose upto 3-5mm difference in any frame. Because these sizes are in MM which makes hardly any difference in size. If your current frame eye size is 52 mm and you are buying frame with eye size 48mm or 49mm that would be okay. In 99% cases almost all the frames will be suitable to you if your face is not too big or small.

A frame that’s slightly wider than your face is a good place to start — no more than a finger width between the temple and your face is a good rule of thumb.

If you’ve already got a pair of glasses that fit, measure from screw to screw on the face front for a good idea of the frame width.

Other Useful Measurements

You’ll also sometimes see other measurements on the temple (arm) of your glasses.

These three numbers represent different parts of the frame:

• Lens width
• Bridge width
• Temple length
