Frame measurements are important to keep in mind if you are wanting a precise fit. They are measured in millimeters.
The width of the bridge section
The horizontal diameter of one lens
The length of the entire temple arm
Understanding what suits your face is important to help you find the perfect eyewear.
Rectangle and square frames draw attention to the eyes and make the face appear smaller.
Most styles look good but it's best to look for a frame that is as wide as the widest part of your face.
Rounded and thinner frames that are slightly wider on the side will have add harmony and softness.
Mirror-opposite frames are recommended; bold on top and light on the bottom.
