In this moment, I will explain about one of the fungtion of Eye Laser. Eye laser can be used to miopy problem, sides It can use to varios of eye problem. Every human have been given with five senses since birth. Although some of them were given less than five, and perhaps some that have a sixth sense. Each sense has a special receptor cells that recognize the changing external environment. But now, we will only discuss the sense of sight only, namely the eye.
Human sense of sight is the eye. We can see and recognize an object because of the cooperation between the eye and brain. Stimuli that occur in the eye will be forwarded to the brain. Here, the brain to process and translate the information received so as to produce an embodiment of the vision.
The human eye-shaped oval, 2.5 cm in diameter or of a golf ball. The front of the eye is protected by a thin and transparent membrane called the conjunctiva. This membrane serves to protect the corneas.
In the conjunctiva flowing tears produced by the tear glands. Tear fluid is useful to keep the eye moist. In tear fluid contained an enzyme called lysozome, which can kill bacteria. In addition, the tear fluid is also useful for cleaning the eye when blinking. Eyelids, eyebrows, and eyelashes useful to prevent entry of dirt or dust from the air and sweat from the head or forehead.
Eye wall has three layers, namely the sclera, choroid, and retina. Sclera has a function to protect the eyeball from the disorder. Blackish brown choroid which contains many blood vessels as nutrients and oxygen to the retina. While the retina is very sensitive to light and has the nerve cells that relating directly to the brain.
A. MIOPI
Impaired sensory system can be experienced by anyone. The disorder is such miopi or farsightedness, the eyeball is a situation that is longer or less oval than the size of a normal eye and the eye lens is too convex. At the time of seeing close objects, shadows falling on the retina and the object is apparent. However, when looking at distant objects, shadows fall in front of the retina so that objects appear blurry. In other words, miopi occurs because shadow fell in front of the retina.
Miopi usually occur in teenage children age 8 or 14 years. Miopi occur because of two factors, namely genetic and environmental factors. From the genetic factor is heredity or congenital, that is if their parents have the disorder or damage to the eye, for example miopi, then later the child may develop damage to the eye like that suffered by their parents. While the environmental factors such as reading while sleeping, was in front of the computer constantly or too long in front of the computer, watching television at close range could cause the eye to be spicy, because the eyes open and hold which will cause soreness, spending tears constantly and It can cause eye cancer that is better known as the retina blastoma. The eyes are often exposed to very bright light or glare can also cause damage to the eye. Another environmental factor that is not normal reading distance and reading by the light of circumstances surrounding the lack of or too dark.
