13 Facts About Human eye

Human eye is a sensory organ, part of the sensory nervous system, that reacts to visible light and allows us to use visual information for various purposes including seeing things, keeping our balance, and maintaining circadian rhythm.

The remaining components of the Human eye keep it in its required shape, nourish and maintain it, and protect it.

The front visible part of the Human eye is made up of the whitish sclera, a coloured iris, and the pupil.

The size of the pupil, which controls the amount of light entering the Human eye, is adjusted by the iris' dilator and sphincter muscles.

Spaces of the Human eye are filled with the aqueous humour anteriorly, between the cornea and lens, and the vitreous body, a jelly-like substance, behind the lens, filling the entire posterior cavity.

Each Human eye has seven extraocular muscles located in its orbit.

Thus, the Human eye can be considered as undergoing rotations about a single point in the centre of the Human eye.

The pupil of the human eye is its aperture; the iris is the diaphragm that serves as the aperture stop.

At this point, the Human eye is moved back to the point where it first saw the train.

Human eye contains enough complexity to warrant specialized attention and care beyond the duties of a general practitioner.

These Human eye symptoms are reported with intensities from mild to severe.

Field studies have found that the prevalence of objective Human eye signs is often significantly altered among office workers in comparisons with random samples of the general population.

Lutein and zeaxanthin are two major carotenoids, found in the macula of the Human eye, that are being researched to identify their role in the pathogenesis of Human eye disorders such as age-related macular degeneration and cataracts.
