Original Ray-Ban RB4345 replacement lenses

If your Ray-Ban RB4345 lenses are scratched, dull or damaged, replacing the lenses is usually smarter than buying a new pair of sunglasses. These original Ray-Ban RB4345 replacement lenses restore the look, protection and optical quality of your frame while saving up to 60% compared with a complete new pair. Free shipping is included.

At ReplacementLenses.net we work with original Ray-Ban lenses every day in our own optical workshop in Granada. We are an official EssilorLuxottica distributor, and qualified opticians check every lens with a lensmeter before dispatch.

Model compatibility

These Ray-Ban replacement lenses are made for the Ray-Ban RB4345 in size 58. The lens shape is round, with a 60 mm lens diameter and Base 8 curvature, so they must be fitted only into the matching frame model and size.

They are not recommended for replicas, copies or frames that only look similar. Even small differences in the groove, bevel or curve can stop an original lens from fitting safely.

How to identify your model and size

Check the inside of the temple arm before ordering. You should find the model reference RB4345 and the size 58. That combination confirms that these original Ray-Ban lenses are the correct replacement for your frame.

If the text is worn away, send us a photo of the inside temple and front of the frame. Our team can help you verify compatibility before you buy.

Material, protection and lens finishes

These Ray-Ban RB4345 lenses are made from polycarbonate, a lightweight and impact-resistant material suitable for everyday sunglasses. The Base 8 curve preserves the original wrap and fit of the frame.

They provide UV400 protection, blocking 100% of UVA and UVB rays. These are not generic tinted plastic lenses; they are original Ray-Ban replacement lenses designed to restore proper sun protection and visual comfort.

Why replace only the lenses

If your RB4345 frame is still in good condition, changing only the lenses is the practical choice. You keep the original frame, avoid unnecessary waste and spend far less than on a complete new pair.

Since 2018 we have helped repair more than 600,000 pairs of glasses, with over 400,000 orders shipped to more than 50 countries. It is a simple way to make your sunglasses look and perform like new again.

Authenticity and logo

Because these are original Ray-Ban lenses, they include the Ray-Ban logo. This keeps the original look of your RB4345 and avoids the colour, shape or quality differences often found in non-branded compatible lenses.

As an official EssilorLuxottica distributor, we supply authentic parts and inspect them professionally. In our Granada workshop we use qualified opticians, professional equipment and MEI Easy Fit Trend technology for high-precision work.

Frequently asked questions

Will these lenses fit any Ray-Ban RB4345?

They are designed for the Ray-Ban RB4345 in size 58. If your temple does not show RB4345 58, check with us before ordering.

Can I use them on prescription RB4345 frames?

These are original sun lenses for the RB4345. Physical fit depends on the frame being the same RB4345 size 58 and not modified in a way that changes the lens groove.

Are they genuine Ray-Ban lenses?

Yes. They are original Ray-Ban replacement lenses and include the Ray-Ban logo.

Do they have UV protection?

Yes, they provide UV400 protection and block 100% of UVA and UVB rays. That is essential for real sunglasses, not just a tinted appearance.

Can I install them at home?

The RB4345 uses a nylon frame and fitting is generally pressure-based. If you are not used to lens replacement, we recommend visiting an optician to avoid stressing the frame.
