If the shield lens on your Ray-Ban RB4440N is scratched, marked or no longer clear, you do not need to replace the whole frame. This original Ray-Ban replacement lens restores the look and sun protection of your Blaze Wayfarer at a much lower cost than buying new sunglasses, with free shipping on qualifying orders.
This replacement part is made for Ray-Ban model 4440, also known as RB4440N Blaze Wayfarer. It is an original sun shield lens, not a pair of separate lenses like those used in classic Wayfarer models. The Blaze design uses a specific single-piece front lens with its own shape and fitting points.
Before ordering, check the inside of your temple arm. The reference should show RB4440, RB4440N or 4440. This is not a universal Ray-Ban lens and should not be fitted to other models, even if the front shape looks similar.
Ray-Ban frames usually show the model, colour code and size on the inner temple. For this product, the available size is 41. That number must match your frame reference to ensure the shield sits correctly on the front.
If your temple reads RB4440N 41, this is the correct type of replacement lens. If your frame has two separate lenses or a different model number, this shield lens will not fit properly.
We use the official colour codes shown for this product, so you can match your current lens or refresh your sunglasses with another available option.
This shield lens is made from polycarbonate, a light and resistant material that suits the single-lens construction of the RB4440N. The Base 2 curve preserves the flatter geometry that defines the Blaze Wayfarer design.
The lens provides UV400 protection, blocking 100% of UVA and UVB rays. With a shield lens, correct geometry and optical quality are essential to avoid uncomfortable visual distortion.
Replacing the lens is the smart way to keep your original Ray-Ban frame, reduce waste and save money compared with buying new sunglasses. If the frame is still in good condition, a new shield lens can make it look and perform like your favourite pair again.
