These lenses are made for the Ray-Ban RB4125 in size 59. They are intended for original Ray-Ban frames with that exact model and size, not for other Ray-Ban models with a similar shape or for replica frames.
Even when two sunglasses look almost identical, the lens groove, bevel, contour and Base 6 curvature must match precisely. That is why checking the model code before ordering is essential.
Look inside the temple arm of your sunglasses. You should find the model code RB4125 and the lens size 59. It is usually printed as a sequence similar to RB4125 59, followed by bridge and temple measurements.
The number 59 refers to the lens width in millimetres. If your frame does not show RB4125 or the size is not 59, these lenses may not fit correctly.
Each lens option listed above corresponds to a real Ray-Ban replacement reference for this product. If you want to keep the original appearance of your sunglasses, choose the same colour code as your previous lenses whenever possible.
These Ray-Ban RB4125 lenses are made of glass, with Base 6 curvature and a sun gradient finish depending on the selected option. Glass lenses provide a clean optical feel and strong everyday scratch resistance.
UV400 protection blocks 100% of UVA and UVB rays. These lenses are not simply tinted: they are designed to protect your eyes outdoors and reduce visual fatigue in bright conditions.
If your Ray-Ban RB4125 frame is still in good condition, replacing scratched lenses is the smartest option. You keep the frame you like, recover optical clarity and avoid paying for a complete new pair when only the lenses are damaged.
It is also a more sustainable choice. Extending the life of your sunglasses means less waste, less expense and the same Ray-Ban style that already fits you well.
These are original Ray-Ban lenses. As original Ray-Ban replacements, they include the Ray-Ban logo as supplied by the manufacturer.
We are an official EssilorLuxottica distributor. Our qualified opticians check lenses with a focimeter before dispatch, so every shipment leaves our workshop with professional optical control.
They fit the Ray-Ban RB4125 in size 59. If your frame shows a different code or you cannot confirm the size, check it before ordering.
We do not recommend it. These lenses are shaped for the original Ray-Ban RB4125 frame, and replica frames often differ slightly in the groove or lens contour.
Yes. This is an original Ray-Ban product and the lenses include the Ray-Ban logo supplied from the official production channel.
Technically it may be possible, but as opticians we usually recommend replacing lenses evenly when there is ageing or colour wear. This keeps the same tone, protection and visual balance on both sides.
The listed lens options for this product are gradient glass options. If you need polarised lenses, you should choose a variant explicitly marked as polarised.
The RB4125 uses a plastic/nylon-type frame construction, so installation is normally done by pressure with gentle heat. If the lens does not seat easily, do not force it; ask an optician.
