Experience the classy style of Ray-Ban RX7148 prescription eyeglasses. The solid frame is made of propionate for durable wear, with solid lines and squared edged that hide thicker lenses, ideal for high negative prescriptions. These rectangular single bridge eyeglasses are great for oval, oblong and round faces. The rubber-covered nylon temples are more comfortable and provide an improved fit with less slipping. The rubberized metal bridge provides a softer look that contrasts subtly with the rest of the frames, for a unique look that will attract attention.
