Photons of light enter the eye and impact on the adjustable Retina (eye lens), they then travel to the nerve tissue at the back of the eye ( Optic Nerve) and are transmitted to the brain, the light photons are translated, and so we see!

The condition known as Glaucoma describes a group of diseases that result in loss of vision by causing permanent damage to the optic nerve. It can lead to loss of central vision and eventual blindness if not diagnosed and treated at an early stage, but glaucoma can often come on suddenly without having any early indications until it is too late

Commonly associated with glaucoma is an elevation in pressure within the eye, known as Intracolular Pressure, although other factors can equally play a role in its development, and it is this elevated eye pressure which damages the optic nerve resulting in vision loss.

Glaucoma usually affects both of the eyes, although it can affect one eye with more severity than the other. There are cases of glaucoma developing even though the eye pressure is normal, and this is thought to be caused by a irregular flow of blood to the optic nerve.

It is estimated that glaucoma is the worlds number one cause of irreversible blindness, and in the USA alone some 6 million people are blind in both eyes as a direct result of glaucoma, and about half of that number are suffering from the disease.

Many people also may not know that they even suffer from glaucoma because the initial onset of the disease gives no early warnings or shows no symptoms. Perhaps the earliest sign of glaucoma is a deterioration in the peripheral vision, but this kind of gradual loss often does unnoticed.
