symptoms of myopia - what is myopia

Myopia is the condition when a person can see things clearly in the distance close (reading or working on the computer), but difficult to see distant objects (traffic signs or bus). Nearsightedness occurs when the eye can not focus light rays exactly on the retina of the eye. We can also define myopia is a function of a false state of the visual apparatus, when people can only see things clearly in the short distant. If we consider the eye as a camera and lens and cornea as a glass: the light passes through and makes a redirect light rays to converge on the retina. And the retina can be compared to the film of take pictures . In the retina it contains many cells sensitive to light and convert light signals into nerve impulses that travel through the optic nerve to the brain. The image will be good if the cornea and lens can be adjusted exactly parallel light rays to converge on the retina. Therefore, healthy people can clearly see distant objects. When nearsighted, the light rays converge in front of the retina and, as a result, the object image is not clearly visible. This phenomenon can occur due to two reasons:

Axis eyeball is longer than normal patients of the retina that pushed back beyond the focus. Normally, the long axis of the eyeball is about 23 mm. In people with myopia, this measurement may be 30 mm or more. Once the axis of the eye is longer than each millimeter, which will cause the increase in number of myopia, three diopters.

  • cornea and lens refract light too strong
  • Axis eyeball is longer than normal patients of the retina that pushed back beyond the focus. Normally, the long axis of the eyeball is about 23 mm. In people with myopia, this measurement may be 30 mm or more. Once the axis of the eye is longer than every millimeter will cause the level of myopia increased by 3 diopters

Myopia reduces vision of humans, so we have difficulties in our life daily.
