Description

Original Ray-Ban RB4314N Nina replacement lenses
If the lenses in your Ray-Ban RB4314N Nina are scratched, replacing the whole pair is not always necessary. These original Ray-Ban replacement lenses restore the look, clarity and sun protection of your sunglasses while saving up to 60% compared with buying a new frame. Free shipping is included.
Model compatibility
These lenses are made for Ray-Ban 4314 / RB4314N Nina in size 54. Similar cat-eye frames are not automatically compatible, because the lens groove, lens diameter and base curve must match the original frame exactly.
The “N” is part of the RB4314N reference, so it should appear on your temple. This product uses Base 2 lenses, which are very flat and help preserve the original flat-lens appearance of the Nina model.
How to identify your model and size
Check the inside of the temple arm and look for the model reference. You should see RB4314N or 4314, followed by size 54. The 54 is the lens size and is essential for choosing the correct replacement lenses.
The lens diameter is 57 mm. If your frame has opened slightly with wear, a professional optical adjustment can help the new lenses sit correctly without stressing the frame.

Material, protection and lens finishes
These are glass lenses, a classic material used in many original Ray-Ban lenses. Glass offers excellent optical stability and a premium feel, while UV400 protection blocks 100% of UVA and UVB rays for solar use.
The Base 2 curve is a key detail for the RB4314N Nina. It keeps the lenses visually flat, so the frame does not lose the design language that made this model stand out.
Why replace only the lenses
Very often, the frame is still in excellent condition while the lenses are scratched or damaged. Replacing only the lenses is a smart way to keep your original Ray-Ban frame, reduce waste and avoid the cost of a complete new pair.
At ReplacementLenses.net we work every day with original Ray-Ban lenses, and our goal is simple: make your sunglasses look and perform like they should again.

Frequently asked questions
Are these lenses only for the RB4314N Nina?
Yes. They are intended for Ray-Ban 4314 / RB4314N Nina in size 54. A similar cat-eye shape does not guarantee a correct fit.
Are they flat like the original lenses?
Yes. The technical specification is Base 2, a very flat lens curve that maintains the original look of the RB4314N Nina.
Are these original Ray-Ban lenses?
Yes. They are original Ray-Ban replacement lenses and include the Ray-Ban logo corresponding to original lenses.
What material are they made from?
They are glass lenses. This gives the lens a high-quality optical feel and keeps the product aligned with the original specification.
Do they provide UV protection?
Yes. They provide UV400 protection, blocking 100% of UVA and UVB rays, which is essential for sunglass use.
Is there a polarized option?
None of the listed lens options is marked as polarized. If you need polarization, choose only a variant that specifically states it.
Can I install them at home?
It can be done with care, but the RB4314N Nina has a pointed cat-eye shape and should not be forced. If you have no experience, we recommend visiting an optician.
Tutorial
Installing Ray-Ban RB4314N Nina replacement lenses
Before installation, check the inside of the temple and confirm that the frame is Ray-Ban RB4314N or 4314 in size 54. Also inspect the frame for cracks, deformation or excessive opening.
Metal frames are usually opened by loosening the rim screw. Acetate or plastic frames are generally fitted by pressure and may need gentle, controlled heat to make the material slightly more flexible. Never use excessive heat, and press the lens evenly rather than forcing one corner.
The RB4314N Nina has a sharp cat-eye design, so extra care is needed around the pointed areas. If the lens does not enter smoothly, stop and have the frame checked. Rimless frames or more complex mounting systems should always be handled by a professional.
If you are not used to changing lenses, visit an optical store. In our Granada workshop, qualified opticians work with professional MEI Easy Fit Trend machinery to ensure a precise fit.
