Original Ray-Ban RB3671CH replacement lenses
These original Ray-Ban 3671CH replacement lenses are the smart way to bring your sunglasses back to life without buying a complete new frame. Keep the fit of your Ray-Ban RB3671 and replace only the damaged lenses, saving up to 60% compared with new sunglasses, with free shipping included.Model compatibility
This is an original Ray-Ban replacement lens set for the RB3671CH model in size 60. It is made to match the Ray-Ban 3671 lens shape, with Pillow geometry, 64 mm lens diameter and Base 6 curvature. Do not fit these lenses into other Ray-Ban models just because they look similar. With metal sunglasses, even a very small difference in outline can create looseness, stress on the rim or an unsafe fit.How to identify your model and size
Check the inside of the temple arm before ordering. You should find a reference such as RB3671 or RB3671CH and confirm that the lens size is 60. That size number is essential for a precise fit. If your frame code has extra letters at the end, focus on the model reference and the size. When in doubt, compare the marking on the temple before choosing your lens option.Main features

Material, UV protection and lens finishes
These sunglass lenses are made from polycarbonate, giving a lightweight feel close to the original wearing experience. All listed lens options are polarized according to their colour code and include UV400 protection, blocking 100% of UVA and UVB rays. The Base 6 curvature helps preserve the original visual geometry of the Ray-Ban RB3671CH. For mirrored options such as 4L - polar grey mirror blue - crystal, always choose by the Ray-Ban colour code for the most accurate match.Why replace only the lenses
If your frame is still in good condition, changing the lenses is more economical, more sustainable and usually much faster than buying new sunglasses. You also keep the frame that already fits your face while restoring the original sun protection. At ReplacementLenses.net we work every day with original Ray-Ban lenses. Since 2018, we have handled more than 400,000 orders and repaired over 600,000 pairs of glasses in more than 50 countries.Authenticity and Ray-Ban logo
These are original Ray-Ban lenses supplied through the official EssilorLuxottica channel. Original Ray-Ban lenses include the Ray-Ban logo, and polarized versions carry the Ray-Ban P marking. In our own optical workshop in Granada, qualified opticians check lenses with a lensmeter before shipping. We use professional MEI Easy Fit Trend equipment and real optical procedures, not just warehouse picking.Frequently asked questions
Are these for RB3671 or only RB3671CH?
These lenses are intended for Ray-Ban 3671CH in size 60. If your temple shows RB3671 and the same size, check the full reference carefully to confirm that the frame geometry matches this replacement.How do I know my size is 60?
The size is usually printed inside the temple arm, next to the model code. For this product, the lens size must be 60 to achieve the correct fit in the metal rim.Are they genuine Ray-Ban lenses?
Yes. They are original Ray-Ban lenses, and we are an official EssilorLuxottica distributor. Original Ray-Ban lenses include the Ray-Ban logo and, for these polarized options, the Ray-Ban P marking.Can I use them in a replica or a similar Ray-Ban model?
We do not recommend it. These lenses are cut for the exact outline of the Ray-Ban RB3671CH, and replicas or similar models may differ by millimetres.Do I need tools to install them?
Because this is a metal frame, the rim is normally opened by loosening the screw. If you are not used to small screws, ask an optician to fit the lenses to avoid scratching the new lens or damaging the frame.Will the colour match my old lenses?
The safest way to match the colour is to choose the same Ray-Ban colour code: AF, 4L, AN, K8 or P1. Using the code avoids relying on screen colour, which can vary.Do they have UV protection?
Yes, these sunglass lenses include UV400 protection, blocking 100% of UVA and UVB rays. That is essential for safe sun use, not just for comfort.Tutorial
Installing Ray-Ban RB3671CH lenses
Before installation, confirm that your sunglasses are Ray-Ban RB3671CH and that the size marked inside the temple is 60. This check is the best way to avoid fit problems.
On metal frames such as the RB3671, the lens is normally replaced by loosening the rim screw, removing the old lens and placing the new one into the groove. Do not force the frame or bend the rim; the lens should sit cleanly before the screw is tightened again.
Acetate frames are usually pressure-fitted with gentle heat, while rimless frames should be handled professionally. If you have no experience with small frame screws or feel resistance, visit an optician to prevent damage to the frame or the new lenses.
