When selecting a new pair of eyeglass frames, there are a number of ways to be sure that they flatter your face to the best extent possible. If you have a strong lens prescription, limit your choice to smaller frames and ask about high-index lenses (which pack more refractive power into a thinner, lighter package). Contrast the shape of the frames with the shape of your face (for instance, square-shaped frames on a round face) for a complementary effect. In terms of color, match your natural pigmentation (such as red frames for a redhead) to create a subtle effect. Otherwise, choose a contrasting color (dark frames with blonde hair and hazel eyes) to make more of a fashion statement. Cat’s-eye frames have an uplifting effect on the face that gives the appearance of a mini face-lift.
