Start with your face shape and frame size (lens width, bridge, temple length) to ensure a comfortable fit; brown square frames often suit most profiles if the proportions are balanced.

Look at fit measurements (lens width, bridge width, temple length), frame material (durability and weight), and lens options (clear prescription vs sunglasses, UV protection).

Consider style cues (brand or design details), comfort features (nose pads, hinges), and whether the frames support your prescription and coatings (anti-reflective, scratch resistance).

Choose frames known for comfort and durability, with prescription-friendly lens options and coatings, and verify the frame’s compatibility with your lens thickness and strength.
