  Eye - Biocrawler   (Site not responding. Last check: 2007-10-07)
Such eyes are typically roughly spherical, filled with a transparent gel-like substance called the vitreous humour, with a focusing lens and often an iris which regulates the intensity of the light that enters the eye.
The eyes are automatically rotated to remain fixed on the object, directed by input from the organs of balance near the ears.
He dissected the eyes of animals, and discovering three layers (not two), found that the fluid was of a constant consistency with the lens forming (or congealing) after death, and the surrounding layers were seen to be juxtaposed.

Because gains in the amblyopic eye may be accompanied by loss in the sound eye, vision must be monitored at appropriate intervals (one week per year of age).
ARC is when the central vision areas of the retinas of the two eyes have two different visual directions, so that when the eyes are crossed the central vision area of the preferred eye has the same visual direction as a point in the side vision of the deviated eye.
Once ARC develops occurrence of paradoxical diplopia (double vision when the eyes are straight) becomes an increasing risk when the eyes are aligned after the age of 6 years.

 FAQ: Ultraviolet, visible and infrared radiation hazards
However the main risk amongst welders is for inflammation of the cornea and conjunctiva, commonly known as 'arc eye' or 'flash'.
The welder protects his eyes by means of a filter glass to absorb the radiation in the dangerous wavelengths, and limit visible light so he can see the progress of the welding process.
Welders frequently suffer arc eye from inadvertent exposure not to their own arc, but to that of another welder working one or two metres away from them.

A congenital eye movement disorder in which there is miswiring of the eye muscles, causing some eye muscles to contract when they should not and other eye muscles not to contract when they should.
People with the syndrome have a limited (and sometimes no) ability to move the eye outward toward the ear (to abduct the eye) and, in most cases, a limited ability to move the eye inward toward the nose (to adduct the eye).
Often, when the eye moves toward the nose, the eyeball also pulls into the socket (retracts), the eye opening narrows and, in some cases, the eye moves upward or downward.

 Welding
Arc eye, also known as arc flash or welder's flash or corneal flash burns, is a painful condition sometimes experienced by welders who have failed to use adequate eye protection.
Arc welding refers to a group of welding processes that use a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point.
Gas metal arc welding (GMAW), sometimes referred to by its subtypes, metal inert gas (MIG) welding or metal active gas (MAG) welding, is a semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun.

 Shielded metal arc welding - Wikipedia, the free encyclopedia
Shielded metal arc welding (SMAW), also known as manual metal arc (MMA) welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode coated in flux to lay the weld.
After the discovery of the electric arc in 1800 by Humphry Davy, arc welding began to develop slowly, and by the end of the 19th century, an early welding process called carbon arc welding was developed.
It can be caused by excessively high current, a long arc, or arc blow, a condition associated with direct current characterized by the electric arc being deflected away from the weld pool by magnetic forces.

The intense light associated with arc welding can cause damage to the retina of the eye, while infrared radiation may damage the cornea and result in the formation of cataracts.
The symptoms of arc eye usually occur many hours after exposure to UV light and include a feeling of sand or grit in the eye, blurred vision, intense pain, tearing, burning and headache.
Eye protection should be used for all welding operations to protect the eyes from bright light, heat, ultraviolet light and flying sparks.
