What About the Nose?
The nose is another factor to take into account. If your nose is bigger than mean, or at least, that’s your impression, pick wider frames that cover more surface of your face. Small frames accentuate the nose, so avoid them. If you have a long nose, choose thick side pieces and/or double bridge glasses.
And now, just go and choose something you like. Because the most important part is feeling comfortable with what you wear.
