These Ray-Ban replacement lenses are made for the Ray-Ban RB4345 in size 58. The lens shape is round, with a 60 mm lens diameter and Base 8 curvature, so they must be fitted only into the matching frame model and size.
They are not recommended for replicas, copies or frames that only look similar. Even small differences in the groove, bevel or curve can stop an original lens from fitting safely.
Check the inside of the temple arm before ordering. You should find the model reference RB4345 and the size 58. That combination confirms that these original Ray-Ban lenses are the correct replacement for your frame.
If the text is worn away, send us a photo of the inside temple and front of the frame. Our team can help you verify compatibility before you buy.
