Original Ray-Ban RB4331 replacement lenses

If your Ray-Ban RB4331 frame is still in good condition but the lenses are scratched, replacing only the lenses is the smart way to make your sunglasses feel new again. These original Ray-Ban 4331 lenses restore the factory look, sun protection and fit, with free shipping and savings of up to 60% compared with buying a complete new pair.

Compatibility with the model

These lenses are made for the Ray-Ban RB4331 model. For the correct fit, check the inside of the temple and make sure the model reads RB 4331 and the size matches this product: size 61. Do not choose lenses only by appearance, as similar Ray-Ban frames can have different lens shapes and bevels.

How to identify your model and size

Ray-Ban temples usually show the model code followed by size information. For this product, the key details are RB 4331 and size 61. When both match, the lens geometry is the right one for this replacement. If the frame has been distorted by heat or long use, installation should be done with extra care.

Material, protection and lens options

The lenses are made from polycarbonate, a lightweight and resistant material used in sun lenses for everyday wear. Our sun replacement lenses provide UV400 protection, blocking 100% of UVA and UVB rays. T3 and T5 are polarized lens options, designed to reduce glare from roads, water and bright surfaces.

Why replace only the lenses

Changing the lenses lets you keep your Ray-Ban RB4331 frame, reduce waste and spend far less than on a new pair of sunglasses. It is the ideal repair when the frame still fits well but the vision is no longer clean due to scratches or wear.

Authenticity and logo

We are an official EssilorLuxottica distributor. As original Ray-Ban lenses, they include the Ray-Ban logo, and polarized versions carry the Ray-Ban P marking. In our own workshop in Granada, qualified opticians check lenses with a lensmeter and work with a MEI Easy Fit Trend machine. Since 2018, we have repaired more than 600,000 glasses and handled over 400,000 orders in more than 50 countries. You can also browse more original Ray-Ban lenses.
