Look inside the temple arm for the Ray-Ban reference. You should find RB4344 followed by the lens size; for this product the required size is 56. If the print has worn off, measure the widest part of the old lens in millimetres and compare the shape carefully, without measuring the outside of the frame.
If you want polarized lenses for the RB4344, choose only the option clearly marked as polarized: 78 – Blue degraded grey polarized – Crystal.
These polycarbonate lenses are light, practical and suitable for daily sun use. They include UV400 protection, blocking 100% of UVA and UVB rays. Depending on the selected colour, the available lens options include uniform, gradient and one polarized finish.
If your Ray-Ban RB4344 frame is still in good condition, replacing the lenses is the smart repair. You can save money compared with buying a new pair of sunglasses, while keeping the original frame you already like.
