Lenses are used in many different things as they allow people to see life through them in many different ways. A major lens in the industry is cylindrical lenses, these lenses are one that make the light that passes through them focus into a straight line instead of a point. This is because cylindrical lenses are parts of a cylinder but cut to what size they are needed. Due to the nature of how they are shaped and cut what happens in more detail is that the light passes through to a line parallel to the intersection of the surface of the lens. There are very different reasons that cylindrical lenses are used, one main one is glasses as this is the main lens used for glasses which helps millions of people all over the world to see correctly as they’re vision that they have without the lens isn’t correct or isn’t as accurate as it could be. Another thing that cylindrical lenses are used in are microscopes which maximizes how much you could see down to the cells in one’s body allowing people to learn about the organisms that are too small for anyone to see with the naked eye. Shanghai Optics are one of the leaders in producing this lens and the lenses that come from the company are trusted in industries across the board as it is known that the lenses are tested heavily for how accurate they are and for how long they last before they ever get sold. Therefore for those that get lenses from the company they know that they will work properly and last for years on end.
