Authentic Ray-Ban lenses with plastic frames are made in one whole piece. If it’s a metal frame, then the central part must look neat and can have small details but no protruding points.
Most often, the lenses are made of real glass, but some can be made of plastic. To know if yours is one of them, go to the manufacturer’s official website.
In the upper right corner of the right lens, you can find the inscription of the Ray-Ban logo. It is engraved on the surface of the lens, so it is impossible to erase it.
On the outside of the temples, there should also be an inscription detailing the manufacturer. In addition, the item’s serial number is usually on the left side and the country of manufacture on the right side.
