about biconcave lens

A biconcave lens is a specific lens with bowl inverted shape similar to the first letter of the English alphabet. It bends in on either side of it. This is the same sort of lens we use in a number of optical devices that aid our vision — eyeglasses and microscopes, for example. But how does this lens work? Let’s find out!

Before we understand how biconcave lenses work, first, we need to know about light. Light is the thing that has made us see things around us. As light goes through a lens, it bends. This bending is referred to as refraction. The amount by which the light is bent depends on two key factors: the shape of the lens and the angle at which the light meets the lens. When another structure or person has a different shape of lens, the light will curve differently.

The Science Behind the Biconcave Lens Design

A biconcave lens is oval shaped in that it curves inwards, which means light rays passing through it will spread out. Their dispersal of light helps to rectify issues with vision. If a person is nearsighted, they have difficulty seeing far away. A biconcave lens assists in bringing these light rays together so that the things further away become easier to see.

These lens are either made up of glass or plastic material. These materials are so special because they bend light differently to air. As light travels get by the lens, it bends because the lens material is not air. This bending is key because it allows the lens to do its job correctly.
