The design of the human eye is similar to most mammals. It
can see an astounding 2.7 million different colors, and can
move up, down and around to allow a 200-degree range of sight.
the eye works
camera, the eye seems to simple enough to use, but go ahead
and check the lens and inner workings - and discover a fascinatingly
complex mechanism that captures and interprets millions of
pictures a day that shapes our view of the world.
the human eye works by allowing light to hit the retina located
in the inner surface of the eye.
The retina contains light
sensitive cells known as cones and rods (looking for all the
world like a tiny microchip) causing them to change chemically,
which in turn triggers nerve impulses to the brain. The brain,
in turn, interprets the data coming in as light and shadow,
form and color all in strikingly vivid 3D.

they are relatively easy to maintain. An important way to

one of the first things that people with a deficiency of this
important nutrient will experience is impaired sight, particularly
with respect to night vision.
maintaining good vision also often comes down to a few easy
steps for resting the eyes and avoiding overuse. Simple measures
like wearing proper UV-rated sunglasses to avoid sun damage
and taking small breaks every once in awhile to rest
the eyes from the glare of a computer screen can prevent
damage that accumulates over time.
