health tips on maintenance of a healthy eye vision

The eye is one of the most important organs in the human body, being the organ or faculty of sight or vision in the body.

The human eye isn't just important in its functions and responsibilities, but is also very fragile and delicate, and requires serious measures to be taken to ensure its continual effectiveness.

The eye plays a powerful role in the body and also has its share of problems and defects that can hinder its operations or ultimately stop its functioning, among which is an ailment known as the eye cataract.

An eye cataract is a eye problem that arises when the proteins in your eye lens begin to break down and causes your sight to become blurry, hazy, or less colorful and the eye's visual quality degrades and progresses to opacity that causes blindness if not treated.

Cataracts is a word derived from the greek word cataractos referring to the turbulent state of rapidly running water.

This occurs when the proteins in the eye form clumps that prevent the lens from transmitting clear signals to the retina.

A cataract develops slowly and begins to interfere with your vision. The eye has a natural lens that bends (refracts) light rays that comes into the eye to enable vision and are situated behind the iris(the colored part of the eye in the area of the pupil), invisible to the naked eye unless it becomes extremely cloudy.

The retina transforms light into neurologic signals that the brain interprets as vision.
