Original Ray-Ban RB4387 replacement lenses

If your Ray-Ban RB4387 frame is still in good condition, replacing only the lenses is the smart way to bring your sunglasses back to life. These original Ray-Ban 4387 lenses are official EssilorLuxottica replacement lenses, with free shipping and savings of up to 60% compared with buying a complete new pair.

Model compatibility

This replacement is made for the Ray-Ban RB4387 model. The square shape, Base 6 curve and lens edging are designed for this specific frame. Other Ray-Ban frames may look similar, but lens fit depends on the exact geometry of the model, so we recommend checking the code before ordering.

How to identify your model and size

Look inside the temple arm of your sunglasses. You should see the model reference RB4387 followed by additional numbers. For this product, the key data are RB4387 and size 56. Do not rely only on measuring the lens horizontally with a ruler; the official frame size is printed by Ray-Ban on the temple.

Material, protection and lens finishes

These original Ray-Ban RB4387 lenses are made from polycarbonate, a lightweight and resistant material for everyday sunglasses. They provide UV400 protection, blocking 100% of UVA and UVB rays. Depending on the selected code, the available lens options include solid colours, gradient lenses and photochromic variants.

Why replace only the lenses

Many sunglasses are left unused simply because the lenses are scratched while the frame is still perfectly wearable. Replacing the lenses lets you keep your favourite RB4387, reduce waste and spend far less than on a new pair. Since 2018, ReplacementLenses.net has repaired more than 600,000 glasses and shipped over 400,000 orders to more than 50 countries.

Authenticity and logo

We are an official EssilorLuxottica distributor. As original Ray-Ban lenses, they include the Ray-Ban logo. In our own optical workshop in Granada, qualified opticians check lenses with a lensmeter before shipping, using professional equipment including MEI Easy Fit Trend.

Frequently asked questions

Do these lenses fit every Ray-Ban RB4387?

They are intended for Ray-Ban RB4387 in size 56. Always confirm the model and size printed inside the temple before ordering.

Will they fit a similar-looking Ray-Ban frame?

No, not safely. Similar appearance does not mean the same lens contour, curve or bevel, and the RB4387 lens is model-specific.

How do I know if my frame is size 56?

The size is printed on the inside of the temple arm near the model code. If you are unsure, send us a photo and our optical team can help you identify it.

Are these genuine Ray-Ban lenses?

Yes, this is an original Ray-Ban replacement product. Original lenses keep the Ray-Ban logo and the optical quality specified for the RB4387.

Do they protect against UV rays?

Yes, these sunglass lenses offer UV400 protection. That means they block 100% of UVA and UVB radiation.

Can I install them myself?

The RB4387 is a plastic frame, so the lenses are usually fitted by controlled pressure. If you feel too much resistance or lack experience, an optician should install them.
