If your Ray-Ban RB4279 frame still fits perfectly but the lenses are scratched, marked or no longer clear, replacing only the lenses is the smart choice. These original Ray-Ban 4279 replacement lenses restore the look, sun protection and feel of your sunglasses while saving money compared with buying a complete new pair. Shipping is free on qualifying orders, and your order is handled by an official EssilorLuxottica distributor with our own optical workshop in Granada.
These Ray-Ban replacement lenses are made for the Ray-Ban RB4279 / 4279 in size 51. They are designed to match the original Phantos lens shape and Base 6 curvature of this model. They are not universal lenses for similar-looking frames, and matching measurements alone is not enough when working with original Ray-Ban lenses.
Check the information printed inside the temple of your sunglasses before ordering. You should find RB4279 or 4279 and confirm that the lens size is 51. Ray-Ban references normally show the model, frame colour code and size; for this product, the key information is model 4279 and size 51.
Choose the colour by its Ray-Ban code if you want the most accurate match with your RB4279. You can also browse our category of original Ray-Ban lenses for official replacement options.
These lenses are made of polycarbonate, a lightweight and resistant material used for everyday sunglasses. The Base 6 curvature is important because it helps the lens sit correctly in the frame without creating unnecessary tension. As original Ray-Ban sun lenses, they provide UV400 protection, blocking 100% of UVA and UVB rays.
The Ray-Ban RB4279 frame is often still perfectly usable when the lenses become worn. Replacing only the lenses gives your sunglasses a renewed look, keeps the frame you already like and reduces waste. It is a practical, sustainable way to bring your sunglasses back to life while avoiding the cost of a full new pair.
Because this is an original Ray-Ban product, the lenses include the Ray-Ban logo. ReplacementLenses.net is an official EssilorLuxottica distributor, and our qualified opticians check each lens in our Granada workshop with a lensmeter before dispatch. Since 2018, we have repaired more than 600,000 glasses and processed over 400,000 orders in more than 50 countries.
Will these lenses fit any Ray-Ban RB4279? They are made for Ray-Ban RB4279 / 4279 in size 51. If your frame shows another size or another model code, the fit may not be correct.
How do I know my size is 51? Look inside the temple and find the size number printed after the model and colour reference. For this replacement, you need size 51.
Are these original Ray-Ban lenses? Yes, this product is listed as original. Original Ray-Ban lenses include the Ray-Ban logo and come through the official EssilorLuxottica supply channel.
Are they polarized? None of the listed lens options for this reference are marked as polarized. If you need polarized lenses, choose a variant that clearly states it.
Can I install them myself? The RB4279 should be handled carefully so the frame is not stressed. If you are not used to lens replacement, we recommend visiting an optician.
Is the curvature the same as the original? The stated curvature for these lenses is Base 6. Using the right base helps the lens sit correctly and keeps the frame geometry stable.
Is it worth replacing only the lenses? If your RB4279 frame is in good condition, absolutely. You save money, keep your original frame and recover UV400 sun protection.
