Original Ray-Ban RB4315 replacement lenses

If your Ray-Ban RB4315 lenses are scratched, worn or no longer comfortable to look through, you do not need to replace the whole pair of sunglasses. These original Ray-Ban RB4315 replacement lenses restore the look, protection and optical performance of your frame, with free shipping and a much lower cost than buying new sunglasses.

Model compatibility

These Ray-Ban replacement lenses are made for the Ray-Ban RB4315 model in size 51. They are designed to match the original lens shape, Base 6 curve and fitting geometry of this specific frame.

Please check the reference inside your temple before ordering. Similar Ray-Ban frames may look close, but small differences in lens shape or groove depth can make the lenses incompatible.

How to identify your model and size

Look inside the temple arm of your sunglasses. You should find the model code RB4315 and the lens size 51 printed as part of the frame information.

If the markings are faded, compare them with your original purchase reference or contact us before installation. A frame that has been bent by heat or heavy use may need adjustment before new lenses are fitted.

Material, protection and lens options

These original Ray-Ban RB4315 lenses are made from polycarbonate, a lightweight and resistant material for everyday sun use. The Base 6 curve preserves the intended fit and visual feel of the original sunglasses.

They provide UV400 protection, blocking 100% of UVA and UVB rays. If you need polarised lenses, select only a variant clearly marked as polarised; the available 71 green and 73 brown options are not listed as polarised.

Why replace only the lenses

Replacing only the lenses is the smart way to bring your favourite Ray-Ban frame back to life. You can save up to 60% compared with buying a complete new pair, while keeping the frame that already fits your face.

It is also a more sustainable choice. At ReplacementLenses.net we have repaired more than 600,000 glasses, processed over 400,000 orders and shipped to more than 50 countries since 2018.

Authenticity and logo

These are original Ray-Ban lenses. Original Ray-Ban lenses include the Ray-Ban logo; when a polarised version exists and is clearly marked as such, the logo appears as Ray-Ban P.

We are an official EssilorLuxottica distributor. In our own workshop in Granada, qualified opticians check lenses with a lensmeter and work with professional MEI Easy Fit Trend equipment.

You can also browse more original Ray-Ban lenses if you need another model.

Frequently asked questions

Will these fit other similar Ray-Ban frames?
These lenses are for Ray-Ban RB4315 size 51. A similar-looking Ray-Ban model can have a different lens contour, so we recommend matching the exact code before ordering.

Where do I find the size?
The size is usually printed inside the temple arm near the model code. For this item, you need RB4315 and size 51.

Are they genuine Ray-Ban lenses?
Yes, these are original Ray-Ban lenses supplied through the official EssilorLuxottica channel. They include the Ray-Ban logo used on original lenses.

Can I install them at home?
Plastic frames are normally fitted by pressure, sometimes with gentle, controlled warmth. If the lens does not seat easily, do not force it; a professional optician can fit it safely.

Do they offer proper UV protection?
Yes, these RB4315 lenses provide UV400 protection and block 100% UVA/UVB. That is essential for real sun protection, not just dark tint.

What if my frame is slightly warped?
A warped RB4315 frame may prevent the new lens from sitting correctly. Have the frame adjusted first to avoid stress on the lens or groove.

Are these lenses polarised?
A Ray-Ban lens should only be considered polarised when the option is clearly marked as polarised. These listed 71 green and 73 brown options are not described as polarised.
