Eating many sweets can lead to eye disease in children. Sugar metabolism generates acidic products, as destruction of calcium and chromium (highly alkaline). The lack of this substance increases the pressure inside of the lens, changing the light refraction of the eye, causing eye more susceptible to myopia.
In addition, the following reasons also increases diseases of the eye:
- limited vision :
Eye of students in urban vision is always limited by the city has many obstacles, hard-looking eyes adjust to near and far.
Gradually adjust the capacity of the eye and eye degenerative only familiar look close, leading to myopia. For city children exposed to natural large eyes adjust to near and far is the prevention of eye diseases as well.
- Lack of sleep :
Due to lack of sleep, the eyes have to work, not relax it gradually reduced capacity to adjust, easily lead to myopia. Make sure to sleep 8-10 hours a day, reducing the intensity of learning and ensuring other conditions (tables, chairs, posture, lighting ...).
- Noise :
The noise levels greater than 90 db, the sensitivity of retinal rod cells of the eye down, the eyes take longer to distinguish brightness.
As the sound up to 95 db, 40% of cases of dilated pupils. When the noise level is 115 db, the ability to adapt to the light intensity decreased 20%, the ability to distinguish color reduction.
- Inhalation of tobacco smoke : The tobacco dicyanogen CN2, if the accumulation in the body will cause poison, clearly affected the operation of the eye.
