The best frame is one you enjoy wearing.
Look past face-shape rules and start with fit, comfort and taste.
Start with comfort.
A frame should feel stable without pressing at your temples or slipping down your nose. Bridge design, width and temple length all matter. An optician can check and adjust the fit.
Try two different directions.
Instead of searching for a single correct frame shape, compare a softly rectangular style with a rounded one. Keep material and color similar at first so you can notice the difference in shape.
Let your lenses have a say.
Your prescription can affect which frames are practical. Ask your optician about lens thickness, visual comfort and frame suitability before buying. Appearance is one part of a decision you will live with every day.
