Eyes - Biology ( Dr. Chen)

Dear Dr. Jau Fei Chen

According to the principle of the natural beauty, the sun and the moon was surrounding us to absorb as  red, orange and yellow orignity of main primary colours of the spectrum. It will  reflect  spectrum of a glass prism as a penetrating object which is  in the world.- ocean blue that are being harmonised with violet rays which can be reaching in the cornea of human anatomy -eyes contacting that tell this is sekunder colours.

In my view, the cornea which is clear, curved layer in front of the iris and pupil to form "a glass prism" in interpreting and analysis the decode of the syntax "Light blue colour in the ocean blue" and behaved as a violet rays which can transform to rainbow colours which is to be melted and crystalised as green, orange, indigo and violet colours.  As the cornea serves as a protective layer in accepting focus light on the retina at the back of the eyes. Besides this, it could be described as the a glass prism that floated in the top 

Sclera is covered by a protective outer layer -eyelids, which is covered by transparent membrane(conjunctiva), which are supported by the edge of cornea.

Sclera is to be regulating the temperature (cold, heat, pain) which is to control the sensor light of violet rays in adjusting the flexibility and elasticity  of the pressure in acceptance penetrating lights  by contraction and dilation blood vessels.

In ergonomic studies, I would like to suggest the supporting  of glass mirror in the vehicles (lorry, cars or airplane) to be incorporated Sclera function which is incorporated violet rays in adjusting and regulating the penetrating  lights acceptance in a optimal temparature. Where your eyes would not be being glared by the sharp light form the heat of the sun during the noon time.

he iris—the circular, colored area of the eye that surrounds the pupil—controls the amount of light that enters the eye. The iris allows more light into the eye (enlarging or dilating the pupil) when the environment is dark and allows less light into the eye (shrinking or constricting the pupil) when the environment is bright. Thus, the pupil dilates and constricts like the aperture of a camera lens as the amount of light in the immediate surroundings changes. The size of the pupil is controlled by the action of the pupillary sphincter muscle and dilator muscle.

Behind the iris sits the lens. By changing its shape, the lens focuses light onto the retina. Through the action of small muscles (called the ciliary muscles), the lens becomes thicker to focus on nearby objects and thinner to focus on distant objects.

The retina contains the cells that sense light (photoreceptors) and the blood vessels that nourish them. The most sensitive part of the retina is a small area called the macula, which has millions of tightly packed photoreceptors (the type called cones). The high density of cones in the macula makes the visual image detailed, just as a high-resolution digital camera has more megapixels.

Each photoreceptor is linked to a nerve fiber. The nerve fibers from the photoreceptors are bundled together to form the optic nerve. The optic disk, the first part of the optic nerve, is at the back of the eye.

The photoreceptors in the retina convert the image into electrical signals, which are carried to the brain by the optic nerve. There are two main types of photoreceptors: cones and rods.

Cones are responsible for sharp, detailed central vision and color vision and are clustered mainly in the macula.

Rods are responsible for night and peripheral (side) vision. Rods are more numerous than cones and much more sensitive to light, but they do not register color or contribute to detailed central vision as the cones do. Rods are grouped mainly in the peripheral areas of the retina.
