Greenberg notes a number of challenges the four-eyed among us have probably encountered. “Too little makeup gets lost behind frames,” she says, “But too much can appear distorted through them. You have to create just the right look with just the right amount of makeup.”

How to achieve this elusive sense of harmony? Consider the balance between lips and eyes when glasses are on. Says Greenberg, “Pick one thing to be a statement—eyes, lips, or glasses—and let the other elements complement that.” In the same vein, eyeshadow shouldn’t compete with colored frames. “Maybe you want to do something graphic with black or brown frames, and then something neutral with colored frames. Colored eye makeup with colored glasses is a little much, unless that’s your jam!” Finally, Greenberg advises applying mascara with caution in order to prevent your lashes from hitting your lenses.
