There is no single frame shape that everyone with a particular face shape should wear. Face-shape charts can offer inspiration, but proportion and comfort are more useful starting points. Look for frames that feel secure without pinching, sliding, or pressing behind your ears. The width should generally relate well to your face, while the bridge should rest comfortably without leaving painful pressure or allowing the glasses to slip repeatedly.
Consider where the top of the frame sits in relation to your eyebrows and how much of your cheek the lower edge touches when you smile. Temple length and nose-pad adjustment can make a major difference, and an optician can often fine-tune the fit. Try several shapes and materials, including lighter options if your glasses feel heavy. If you wear a strong prescription, ask how frame size and lens thickness may affect the finished appearance and comfort.
Think about how you will use the glasses: all-day wear, reading, work, sports, or occasional backup. Durable hinges, a stable fit, and easy maintenance may matter more than a trend. Bring your current glasses when shopping if you like their fit, and explain what you would change. A flattering frame should also allow your lenses to be centred appropriately for your eyes. Choose something that feels like you, and ask for an adjustment if the fit is not right.
