A cataract is a clouding of the eye's natural lens. The word cataract is derived from a Greek word meaning "waterfall" (looking through falling water). Cataracts are most commonly caused by chemical changes within the lens of the eye, which is thought to be part of the natural aging process. But cataracts may also result from ultraviolet damage, heredity, alcohol, smoking, trauma, disease, or prolonged use of certain medications.
Depending on the degree of cloudiness, a cataract will cause a gradual decrease in vision.
Dipole moment is the polarity measurement of a polar covalent bond. The higher the polarity of a molecule the more is the dipole moment. It refers to the molecule which makes a dipole and it is equal to the product of charge on the atoms and the the distance between the two atoms which are bounded with each other.
liquid to liquid separation of γ-crystallin in the eye leads to cataract formation which accounts for the charge distribution which is done through a dipole moment therby corrects this probelm.
