The right pair of glasses should rest comfortably on the bridge of your nose, and should not press against your forehead or cheeks. But they shouldn't rest so far towards the end of your nose that they slip when you squint or wrinkle your nose.

Are your glasses supposed to touch your cheeks?

Your glasses shouldn't rest on your cheeks when you smile. They should be level on your face. The temples of your eyeglass frames should feel secure around or over your ears, without pinching or feeling uncomfortable.

How do you know if sunglasses are too big for your face?

If the frames touch your cheeks, it means they're too big for your face. Show your eyebrows – don't hide your eyebrows behind your glasses, or the overall effect will be odd. Choose a size that lets your eyes peek out from the center of the glasses.
