These Ray-Ban replacement lenses are made for the Ray-Ban RB4397 model in size 54. For a precise fit, your frame reference must match RB4397 and the lens size must be 54. Similar-looking Ray-Ban frames are not enough: small differences in the irregular shape, bevel or Base 6 curve may prevent the lens from fitting safely.
Check the inside of the temple arm. You should find the model code RB4397 followed by size information; the lens size required for this product is 54. If the print has worn off, compare the lens shape carefully and measure the widest part of your current lens before ordering.
Where a specific colour option states plastic, that variant information takes priority over the general lens material shown in the product attributes.
These lenses are designed for sun use and provide UV400 protection, blocking 100% of UVA and UVB rays. The Base 6 curve keeps the optical geometry required for the RB4397 front. The 83 option is the polarized brown lens option; for any other finish, always choose the exact variant shown in the selector.
If your Ray-Ban frame is still in good condition, replacing only the lenses is usually the best value decision. You keep the frame that already fits your face, reduce waste and avoid paying for a full new pair of sunglasses. You can explore more options in our original Ray-Ban lenses category.

Do these lenses fit any similar Ray-Ban frame?
No. They are made for the Ray-Ban RB4397 in size 54. Even a very similar frame can have a different groove, shape or curve, which would affect the fit.
How do I know if my RB4397 is size 54?
Look inside the temple arm for the model code RB4397 and the lens size 54. If the marking has faded, measure your current lens and compare the shape before placing the order.
Are these original Ray-Ban lenses?
Yes. These are original Ray-Ban replacement lenses supplied through official EssilorLuxottica distribution. They include the Ray-Ban logo, and the polarized option includes the Ray-Ban P marking.
Can I choose polarized lenses if my original lenses were not polarized?
Yes, as long as you select a variant marked as polarized, such as 83 – polarized brown – plastic. Compatibility depends on the RB4397 model and size 54, not on whether your previous lenses were polarized.
Is it better than buying new sunglasses?
If your frame is in good condition, replacing the lenses is usually the most sensible option. You save money, reduce plastic waste and keep the sunglasses that already feel right on your face.
Can I install them myself?
The RB4397 lenses are typically fitted by pressure into the frame, but you should work slowly and avoid forcing the front. If the lens does not seat easily or you are not used to this type of mounting, visit an optician.
Do they provide real UV protection?
Yes. These sun lenses provide UV400 protection, blocking 100% of UVA and UVB rays. That is essential for visual safety and one of the key advantages of original lenses over low-quality copies.
