Original Ray-Ban RB8148 HEXAGONAL replacement lenses

Bring your Ray-Ban RB8148 HEXAGONAL sunglasses back to life without buying a new frame. These original Ray-Ban replacement lenses let you keep your premium frame, save up to 60% compared with new sunglasses, and enjoy free shipping from an official EssilorLuxottica distributor.

Model compatibility

These lenses are made for the Ray-Ban 8148, also known as RB8148. The irregular hexagonal shape and Base 6 curve are intended for this specific frame. They should not be used on copies or visually similar models, because even small differences in the rim can affect the fit.

How to identify your model and size

Check the inner side of the temple. You should see the RB8148 reference followed by the lens size, such as 51 or 54. Choosing the correct size is essential for a secure and accurate fit.

If the marking has worn off, measure the maximum lens width in millimetres with a ruler. This product is available in sizes 51 and 54, with 56 mm and 59 mm diameters depending on the variant. When in doubt, confirm the size before ordering.

Material, protection and lens finishes

These lenses are made of glass, a material appreciated for its optical clarity and premium feel. All listed lens options are polarized, helping reduce glare from roads, water, sand and bright reflective surfaces. The T0 option also features a gold mirror finish over a polar blue lens.

Why replace only the lenses

The RB8148 is a valuable Ray-Ban frame. If the frame is still in good condition, replacing only the lenses is a smarter, more sustainable and more economical choice than buying complete sunglasses. You keep the frame you already like while restoring vision, style and sun protection.

We are an official EssilorLuxottica distributor. As original Ray-Ban lenses, they include the Ray-Ban logo and, on polarized versions, the Ray-Ban P marking. In our optical workshop in Granada, qualified opticians check every lens with a focimeter before dispatch.

We work with a MEI Easy Fit Trend machine and have repaired more than 600,000 glasses, processed over 400,000 orders and served customers in more than 50 countries since 2018.
