The base-up triangle is wider at the forehead with a narrow chin.

People with this face shape should consider a more understated frame with a softer shape. The opposite of a base down triangle-shaped face, base-up triangle faces, similar to heart-shaped faces, need glasses with the opposite styling. Instead of making your eyeglasses more noticeable, you should do the opposite.

Choose light frames, like rimless or wireframe, and in a light color. The best shapes to look for are round, square, or rounded squares. These frames work best to lengthen the face appearance, de-emphasizing the wider forehead area.
