The human eye sits in the bony eye socket (the orbit), which is made up of the facial skull bones. The eye has six muscles attached to it, which move it in all directions. It’s surrounded by fat, which cushions it.

At the front, it’s covered by the eyelids , it keep the surface moist, protect the eye and are used in facial expressions.

The eye is supplied by blood that comes up the neck and through the skull and reaches the eye from behind it. The nerve supply to and from the eye also comes from behind the eye.

When images in the form of light enter the eye, they are directed to the back of the eye, through the pupil, and travel to the brain via the optic nerve.

The brain interprets the information and tells you what you have seen.

The part of the brain that does this work is at the very back of the head and is called the occipital cortex.

The cornea is the transparent covering of the iris and pupil. It protects your eyes from dirt and germs, as well as some of the sun’s UV rays. If your cornea becomes damaged you will experience distorted vision, because the light that enters your eye is interfered with.

Some people are born with mismatched eye colours. This condition is known as heterochromia, and is usually the result of a relative lack or excess of pigment in one eye. It is most often inherited, but may also occur due to disease or injury.

Wider pupils can suggest excitement. Any positive thought can serve to dilate your pupils. For example, when you look at someone you are attracted to, they will expand up to 45%. However, dilating pupils can also mean you are scared.

A woman’s eyesight can be affected by pregnancy. While hormones are raging and physical changes are occurring, it is possible for a woman to experience problems with her sight.
