Most of the focusing power in the eye occurs along the front surface of the eye, at the cornea (the clear 'window' in the front of the eyeball), or within the lens, which sits behind the cornea inside the eye.

Glaucoma
Glaucoma is a condition that causes damage to your eye's optic nerve and gets worse over time. It's often associated with a buildup of pressure inside the eye.

Chalazion symptoms
Swelling of the upper eyelid may occur gradually over weeks. The condition rarely involves the lower eyelid.
A chalazion appears as a localised hard lump that may grow as large as an eighth of an inch.
Occasionally, you may feel pain and your eyelid may be red.
Pupula Duplex
Pupula Duplex is a latin term which means double pupil. Its often referred by some by the following terms "evil eye", double iris and in medical literature as Polycoria.
Colour Blindness
Color blindness results from an absence of color-sensitive pigment in the cone cells of the retina, the nerve layer at the back of the eye that converts light into nerve signals that are sent to the brain.
Cataract
The cataract is the large area of opacity (grey) where the pupil would normally be seen. A cataract is a progressive opacity of the eye's lens, due to changes in the structure of the lens. It causes blurred vision that can lead to blindness if it is untreated. When required, surgical treatment can restore vision. The lens is removed and a plastic replacement inserted.
