Start with the prescription and the way the glasses will be used. Daily distance wear, reading, progressive lenses, driving sunglasses, and computer work can call for different frame and lens choices.
Compare the full price before checkout. A low frame price can change once lens type, high-index material, coatings, shipping, and remake rules are included.
Use frame measurements to avoid fit surprises. Bridge width, temple length, lens height, and frame width are especially important for progressive lenses and higher prescriptions.
