If you choose eyewear to suit your face, you will see well and look good.
Choose frames that create a balance and select a frame that is as wide or wider than the broadest part of your face.
Make sure your glasses are in proportion with the rest of your face. Frames that are too large or too narrow, will create asymmetry and make your facial features appear imbalanced.
First, you need to identify your face shape.
Pull your hair away from your face and look straight on into a mirror. Trace the outline of your face on the mirror using a whiteboard marker, or something that can be removed easily.
Take a close look at the overall shape that has been drawn and identify which shape your face is closest to. Nobody is a perfect, circle, square or any other shape, you just want to pick a shape that is closest to what your face is.
The main face shapes are oval, diamond, round, triangular, square and rectangle.
