This Science Tube video, from Teachers TV, helps children to understand about light and seeing. There are five separate, short clips:

Day and night uses time-lapse film and animation from space. It shows how sunlight provides daylight and how the spin of the Earth causes night in the side shaded from the Sun.

Cinema trip explores light sources, revealing how light can travel through some materials but not others. It describes how light shines through a film to produce the image.

Inside an eye shows an animal's eye being taken apart to find out how it works. Not for the squeamish.

Trick of the light looks back at how the Victorians used mirrors and lenses to set up the camera obscura. This is a large room into which scenes from outside the room are viewed through an opening and projected onto a screen.

Seeing the light goes into the laboratory to explain reflection, using mirrors, torches and lasers to demonstrate how light travels in a straight line.
