Original Ray-Ban RB4221 replacement lenses

If your Ray-Ban RB4221 frame still fits well but the lenses are scratched, worn or no longer look clean, replacing only the lenses is the smart repair. These original Ray-Ban 4221 lenses restore the look and sun protection of your sunglasses for much less than buying a new pair, with free shipping and the reassurance of an official EssilorLuxottica distributor.

Model compatibility

These Ray-Ban replacement lenses are made for original Ray-Ban RB4221 frames. They should not be ordered for other Ray-Ban models simply because the shape looks similar.

In eyewear, small differences in lens shape, curve or size can change the fit completely. Always check that your frame is marked RB4221 before choosing this replacement.

How to identify your model and size

Look at the inside of the temple arm. Ray-Ban frames usually show the model reference, the frame colour code and the lens size in the same line.

For this product, the available size is size 50. That number refers to the lens width in millimetres and must match your frame. If your sunglasses show a different size, do not order this replacement without checking compatibility first.

Material, protection and lens finishes

These Ray-Ban RB4221 lenses are polycarbonate, a lightweight and resistant material commonly used in everyday sunglasses. The Base 6 curve helps preserve the intended optical and fitting geometry of this model.

They provide UV400 protection, blocking 100% of UVA and UVB rays. The available lens finishes include gradient options and a total blue mirror option, only in the variants listed for this product.

Why replace only the lenses

If the frame is still in good condition, replacing the lenses is usually the most cost-effective choice. You can bring your Ray-Ban RB4221 back to life for up to 60% less than buying a new pair of sunglasses.

You also keep the frame that already fits your face and avoid unnecessary waste. It is a practical, sustainable repair that gives a well-loved pair of Ray-Ban sunglasses many more seasons of use.

Authenticity and Ray-Ban logo

These are original Ray-Ban lenses, not generic compatible lenses. Original Ray-Ban lenses include the Ray-Ban logo, and are supplied through the official EssilorLuxottica channel.

At our own workshop in Granada, qualified opticians check lenses with a lensmeter and professional equipment such as the MEI Easy Fit Trend. Since 2018, we have repaired more than 600,000 pairs of glasses and shipped over 400,000 orders to more than 50 countries. You can also browse more original Ray-Ban lenses.

Frequently asked questions

Will these lenses fit any Ray-Ban frame that looks similar?
No. These lenses are intended for original Ray-Ban RB4221 frames only. Similar-looking models can have different shapes, sizes or curves.

How do I know if my RB4221 is size 50?
Check the inside of the temple arm. Your frame should show RB4221 and the lens size 50 for this replacement to be the correct size.

Are these glass lenses or plastic lenses?
These lenses are polycarbonate. It is a light, resistant material suitable for daily sunglass use.

Do they provide real UV protection?
Yes. These Ray-Ban RB4221 replacement lenses provide UV400 protection, blocking 100% UVA/UVB.

Can I order polarized lenses for this frame?
Only choose variants that are clearly listed as available on the product page. If a lens option is not marked as polarized, it should not be assumed to be polarized.

Can I install them myself?
Some experienced customers can replace lenses at home, but the frame must not be forced. If you are unsure, we recommend having the RB4221 lenses fitted by an optician.

Is replacing the lenses worth it?
Yes, if your RB4221 frame is in good condition. You keep your favourite sunglasses and restore their performance for a fraction of the cost of a new pair.
