People who are suffering from myopia will look the distant things less clearly and if they want to see clearly, they often need to squint their eyes. Many signs and symptoms of myopia in children and adult will be named in this article
Before introducing about some signs and symptoms of myopia, you should also need to know what is myopia and what can it do with our eyes.
I. What Is Myopia?
Myopia is the condition when a person can see things clearly in the near distance (reading or working on the computer) but difficult to see distant objects (traffic signs or bus number). Myopia occurs when the eye cannot focus light rays exactly on the retina of the eye. We can also define Myopia is a false state function of the Visual apparatus, when people can only see clearly those things in the near distant. If we consider the eye as a camera and the lens and the cornea as a glass: the light passes through and makes a redirect to the light rays converge on the retina. And the retina can be compared with the film to take pictures. On the retina contains many sensitive light cells 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 see clearly distant objects. When suffering from myopia, the light rays converge in front of the retina and as a result, the image of the object is not clearly visible. This phenomenon can occur due to two reasons:
Shaft eyeball is longer than normal patients to retinal 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 eyeball axis is longer than each millimeter, it will make the number myopia increase by 3 diopters.
- Cornea and lens refract light too strong
- Shaft eyeball is longer than normal patients to retinal pushed back beyond the focus. Normally, the long axis of the eyeball is about 23 mm. In people with myopia, this measurement can be 30 mm or more. Once the eyeball axis is longer than each millimeter will make the level of myopia increased by 3 diopter
Myopia reduces vision of human beings, making us have difficulties in our daily life. The pupils from the age of 7 to 16 years are very easy to suffer that degree myopia progresses faster due to the level of work looking at nearby many eyes it is a dangerous thing because myopia appears as soon as the level of increase of the glasses as quickly.

If your weak eyelid has to be exertion for a long time, it will increase the risk of myopia.
III. When Would Myopia Appear And Develop?
The refraction usually happens at the age of 8 to 10. The level of diopter will increase gradually and stops when you reach 16 or 18 year olds. Each year it will rise from 0.5 to 1 degree on average. The sooner myopia appears as soon the faster its level up.
There are also some cases of refraction appears while you are still being very small, often related to genetic factors. Some cases occurred in adults when there are events on health such as after pregnancy, an accident or sickness, they may appear new refraction or make the level of diopter worse
If you can detect myopia in time, wear glasses in the right degrees and monitor periodically the refraction will stabilize, after 40 years it will decrease because of presbyopia neutral status. In some cases (myopia or astigmatism), there are a number of complications such as the phenomenon of flies, a Flash of light, and most heavily is the retinal, can lead to blind.
