These lenses are made for Ray-Ban model 4291 in size 58. Correct compatibility depends on the code printed on your frame: the model must match RB4291 and the lens size must be 58mm.
The RB4291 frame uses nylon, a flexible and durable material that allows pressure-fit lens replacement when handled carefully. If your sunglasses match the 4291 model and size 58, these lenses are designed to fit the original frame geometry.
Look on the inside of the temple arm before ordering. You should find the Ray-Ban model reference, usually shown as RB4291, followed by the size. For this product, the correct size is 58.
The 58mm size refers to the lens width. Do not rely only on the overall shape of the sunglasses, as similar Ray-Ban frames can use different lenses. Always check the temple code first.
