Lens Refraction

Lens refraction in optics is the phenomenon of refraction of light rays at the interface between two media. This phenomenon underlies the functioning of our eyes. When viewing a well-lit object, rays from it pass through the lens of the eye and then hit the retina. There they are refracted and after processing by the brain we get an image of this object.

For each type of eye, refraction is carried out differently. For example, a person has a monochromatic eye (one visual lens - the lens), which consists of 5 layers: the lacrimal membrane, the aqueous membrane, the iris, the ciliary body and the retina.
