The lightweight comfort of rimless glasses feels good on your face. Spring hinges or a wraparound rimless eyeglass frame mold to your face, eliminating the guesswork. Both the lightness of the rimless reading glasses and the contouring frame will please your eyes, literally, and allow you to focus better.
No matter what your face shape, rimless eyeglasses feel good. You should however consult with an optometrist/optician for a good fit between your rimless eye glasses and your face.
