At ReplacementLenses.net, shipping is free and every order is supported by our own optical workshop in Granada.

Model compatibility

These lenses are intended for the Ray-Ban RB3447N model, with a round sun lens and metal frame. The essential point is the Base 2 curvature: this is the flat-lens version, so it must not be confused with visually similar Ray-Ban models that use more curved lenses.

Even if another frame looks almost identical, a small change in rim shape, lens size or curvature can stop the lens from fitting correctly. Always check the code printed inside the temple before ordering.

How to identify your model and size

Look inside the temple for a code such as RB3447N followed by several numbers. The lens size is usually shown as 47, 50 or 53, which are the available sizes for this product. This number refers to the horizontal lens width in millimetres.

If the marking has worn away, measure the widest horizontal point of your old lens from edge to edge with a ruler. If you are between two sizes, compare the shape carefully and contact us before placing the order.

Material, protection and lens finishes

These lenses are made of glass, a material known for excellent optical clarity and good natural scratch resistance compared with many plastic materials. Because the RB3447N uses Base 2 flat lenses, choosing the correct original replacement is important to keep the frame looking as it should.

All listed options are sun lenses with UV400 protection, blocking 100% of UVA and UVB rays. The lens options include classic, gradient and mirror finishes, always identified by the real product colour codes.

Why replace only the lenses

If your metal frame is still in good condition, replacing only the lenses is a smart repair. You recover clear vision, original style and certified sun protection for much less than the cost of new sunglasses.

It is also a more sustainable choice: keep a quality frame in use and avoid unnecessary waste. Since 2018, we have repaired more than 600,000 glasses and processed over 400,000 orders in more than 50 countries.

Authenticity and logo

We are an official EssilorLuxottica dealer. As original Ray-Ban lenses, they include the Ray-Ban logo on the lens. Qualified opticians check each lens with a lensmeter in our Granada workshop before preparation.

Frequently asked questions

Are these lenses for the standard RB3447?

These lenses are for the RB3447N flat Base 2 version. If your frame is marked RB3447 without the N or has more curved lenses, check compatibility before ordering.

How do I choose 47, 50 or 53?

The size is normally printed inside the temple after the model code. If it has faded, measure the maximum horizontal width of your old lens.

Are they glass or plastic?

The lenses are made of glass. That helps preserve the optical feel expected from original Ray-Ban lenses.

Do they protect against UV?

Yes, these sun lenses provide UV400 protection. They block 100% of UVA and UVB rays.

Do original lenses have the Ray-Ban logo?

Yes, original Ray-Ban lenses include the Ray-Ban logo. It is one of the key details that separates original replacements from generic lenses.

Can I install them at home?

Metal frames are usually opened by carefully loosening the rim screw. If you are not used to handling glass lenses, we recommend having them fitted by an optician.
