Why Are There MoreAnd More People Wearing Eyeglasses?

All say that the eyes are the window of the heart, and myopia seems to give the window with a layer of ash.There are more and more myopia these years, and some even wear glasses at an early age.Today we are going to talk about myopia.

1.Why are there more and more people wearing glasses?

Nowadays, more and more people are wearing glasses. Although in addition to myopia, there are distant vision, strabismus, astigmatism and other vision problems, which need to be corrected by wearing glasses, but most of the people wearing glasses are still myopic people, in the new myopia people, most of them are children and teenagers.
From the current relevant research, although the cause of myopia is not related to genetics, but, the degree of using the eye, habits, the use habits of electronic screen products, as well as the time to participate in outdoor activities, also has an obvious relationship with myopia.

2.Can food supplement or not well cure myopia?

There are many people who believe that "food tonic" can achieve a very magical effect, often eating certain specific foods can cure yourself.
But at least for myopia, those legendary good food for the eyes, such as pig liver, wolfberry and what, can not cure myopia.
In addition to dietary supplements, there are many unreliable products such as training instruments, myopia masks, herbal treatment for myopia, acupuncture for myopia... Don't believe it in everyone!

3.Not to 1.0, is the poor vision?

Visual acuity is the most common eye examination, and many people think it is clear that 1.0 or less is normal.
But this standard is not applicable to everyone, and for young children, it cannot be judged by 1.0.
Because people can not see everything all their life, the newborn can only see the movement of the objects in front of them, and in about 4 months can they see the shape of the face. With the stimulation of the external environment, the visual system develops rapidly and the vision is gradually improved.
For children, normal vision is like this:
3~5 years old: you can see 0.3~0.7;
5~7 years old: You can see 0.7~0.9;
Over 7: Can see 1.0 or above.
Adults and older children can decide whether to go to the eye.

4.What way is there to prevent myopia?

Modern scientists have found that poor habits of close eye use and long eye use are important environmental risk factors, such as eyes too close to books, lighting too strong or too weak, uninterrupted reading for hours, and watching mobile phones and other electronic devices for a long time.
To prevent myopia, ophthalmologists suggest paying attention to these aspects in life:
Keep read at least 25~30 cm, walking or bed.
Use double lighting when reading, namely, when there is an appropriate brightness dispersion lighting (such as the sun light on the ceiling), place another desk lamp 50 centimeters away from the book.
Read 45~50 minutes rest 10 minutes, rest preferably in outdoor natural light or overlooking.
Increase outdoor time for activities appropriately. This is particularly important for children, and epidemiological studies show that the longer the child is outdoors, the lower the risk of myopia.
