Understanding How the Human Eye Adjusts to Different Distances
This video explains the power of accommodation of the human eye, which is the ability of the eye to adjust its focal length through the ciliary muscles and the lens. It also discusses the least distance of distinct vision and the far...

Correcting Vision _ GCSE Physics
Vision defects generally come in two different ways called short sightedness and long sightedness. A person who has short sight can see near objects clearly, but struggles to focus on distant ones. This is caused by one or two reasons....

Convex Lenses: Refraction and Image Formation
The video is a lecture on convex lenses, explaining the way they work to bend and focus light. The speaker defines what a lens is, describes how convex lenses function, explains how to construct a ray diagram with a convex lens, and...

Converging lens focussing rays of light, animation.
This is a biconvex lens. The paths of the rays are changed due to refraction, which occurs as the speed of light in glass is lower than the speed in air. The point at which the rays meet is called the focus, and the distance from the...
