Our Ray-Ban RB4387 Replacement Lenses are made for one job: fitting the Ray-Ban RB4387 frame you already own. They are aftermarket lenses, cut in our workshop, in the tint you choose on this page. You may also see this model written as Ray-Ban 4387.

Ray-Ban RB4387 Replacement Lenses: fit and measurements

Angular lenses have corners, and that is where a poor cut shows first: a gap at the rim or a lens that will not sit flat. This model is sold in size 56. Each lens is about 62 mm in diameter and 49 mm high. Before ordering, read the code printed inside the left temple: it must say RB4387, followed by the size. A lens from another model will not seat properly even if it looks similar.

• Model code: RB4387
• Size: 56
• Lens: 62 mm diameter, 49 mm high

Lens material, colours and coatings

There are 20 colours on this page. Solid tints: blue, green, pink, red, yellow, brown and grey. Gradients: grey gradient and brown gradient. Mirrors: gold mirror, violet mirror, ice blue mirror, black mirror, blue mirror, green mirror and red mirror. Photochromic, which darken in sunlight: photochromic blue, photochromic green and photochromic grey. Clear lenses are also available, with a blue-light filter option. Tinted lenses are polycarbonate with a Base 6 curve and UV400 protection; clear lenses are CR39 or polycarbonate, depending on the coating. Most tints can also be ordered polarized to cut glare: the options for each colour appear under the colour selector. Blue, pink and red come non-polarized only. For driving or everyday wear, most people choose between grey, green and brown: grey is the most neutral, green the most natural and brown the warmest. When you pick a colour, the photo above shows it on this frame.

How to fit them

The front of the RB4387 is injected plastic. Push the old lens out from the back, pressing near the edge rather than the centre. Then seat the new one in the groove starting at one end and press round until it sits evenly all the way, without twisting the frame. If you are not confident, an optician can do it for you.

Why change the lenses and keep the frame

A frame that fits well is worth keeping. New lenses deal with scratches or wear, and they let you change the tint if you fancy a different look. If you own another pair, there are more models in our Ray-Ban replacement lenses section.

Frequently asked questions

Do I get a pair or a single lens?

A pair: one left lens and one right lens, in the tint you select.

Are they made by Ray-Ban?

No. They are aftermarket lenses, made independently to fit the RB4387. Ray-Ban does not make or endorse them.

What warranty and returns do they have?

A 3-year warranty on manufacturing defects and 14 days to return them.

Can they take a prescription?

These are sold as non-prescription lenses, so they carry no correction.

Can they be polarized?

Most tints can, and you choose it under the colour selector. Whichever you pick, every sun lens has UV400 protection.
