If your Ray-Ban RB4351 frame is still in good condition but the lenses are scratched, replacing only the lenses is the smartest way to bring your sunglasses back to life. These original Ray-Ban 4351 lenses restore clear vision, UV400 protection and factory fit, with free shipping on qualifying orders and at a much lower cost than buying a new pair.
These Ray-Ban replacement lenses are made for the Ray-Ban RB4351 sunglasses model in size 59. As an original product, the lens shape, edge thickness and Base 6 curve are made to match this specific frame geometry.
The frame colour does not affect compatibility when the model and size are correct. Always check the inside of your temple before ordering.
Open the inner temple of your sunglasses and look for the RB4351 reference followed by the size information. This product is for size 59.
We do not recommend relying only on measuring your old lens with a ruler. Small differences in measuring angle can lead to mistakes, while the temple marking is the safest way to confirm the correct replacement.
These replacement lenses are made from polycarbonate, a lightweight and resistant material for everyday sunglasses use. They include UV400 protection, blocking 100% of UVA and UVB rays.
If you want to reduce glare from road surfaces, water or bright reflections, choose a lens option marked as polarized, such as 83 – Polarized brown or 9A – Green polarized. For a softer look, 11 – Gray gradient keeps the original gradient style.
Replacing the lenses lets you keep your Ray-Ban RB4351 frame instead of throwing it away. It is a more sustainable choice and can save money compared with buying a complete new pair of sunglasses.

Will these fit any Ray-Ban 4351? They are made for Ray-Ban RB4351 in size 59. The model and size printed inside the temple must match for a correct fit.
Are they suitable for the optical RB4351-V version? This product is listed as a sunglass replacement for RB4351. If your frame is an optical version, check the exact reference before ordering.
Do the lenses carry the Ray-Ban logo? Yes, original Ray-Ban lenses include the Ray-Ban logo. Polarized lens options include the Ray-Ban P marking.
Can I install them at home? The RB4351 is a synthetic frame and lenses are usually fitted by pressure with the right technique. If you are not used to this type of installation, an optician is the safest option.
Which colour should I choose? Choose the code that matches your original look or the use you need. The polarized 83 and 9A options are ideal when glare reduction is a priority.
What if I ordered the wrong model? Before installing, compare your temple marking with RB4351 and size 59. Never force the lens if it does not sit naturally in the frame groove.
