Your eyes at a glance

Most people do not think about their eyes until they have a reason for it, usually when they notice discomfort. But the eye is one of the most complex organs in the human body.

This inch-long regiment detects light, converts it into electrical signals, which are then sent to the brain so that it can interpret what you are looking at. Think of it as a visual phone game or a photo shoot.

The front of your eye (consisting of the iris, cornea, lens, pupil) is filtered under light; the image focuses on the membrane behind the eye, called the retina. This membrane sends electrical signals to the optic nerve, which then sends them to the brain so that you can understand what you are seeing.
