First, open the glasses feet in a flat place, and then see if the two glasses feet are one high and one low. If not, you still feel high and low. It's best to take them to the optical shop to see if there is a problem with the frames. If not, there may be something wrong with the ear position.
The size of the frame should be appropriate. Some parents and children think that bigger frames look better, while others think that smaller frames are not easy to fall off. These are not comprehensive. Because the pupil position of children's eyes is just opposite to the center (optical center) of the lens, the lens and the eyeball surface are kept at the position of 12mm, which can play a good role in correction and treatment.
If the frame is too large, the eyes are far away from the optical center and biased to the inside of the glasses, resulting in prism effect, which will cause blurred vision, decreased vision, sore eyes, headache and other visual fatigue symptoms, and aggravate the development of ametropia. If the frame is too small, the eyes will tilt outward, which is also far from the optical center of the lens. After a long time, the temples on both sides will tightly press the intraocular bone, and the temporal side will also affect the normal development of the face. Therefore, it is necessary to choose the child's frame according to the development of the child's head, face and eye socket, and replace it in time with continuous development.
The correct concept of wearing glasses
Generally, glasses should be worn often after glasses are worn, because glasses make the eyes with ametropia tend to be normal, and people with normal eyes can get close to or acquire their due abilities. Wearing the right glasses will change everything and provide a prerequisite for approaching or reaching a normal child, which may help him become a promising talent. Don't underestimate the role of glasses.
People with hyperopia use different degrees of adjustment when reading than normal eyes, and are prone to vision fatigue, blurred vision, eye fatigue, eye pain and even headache and irritability, so reading cannot last long, which affects work and study. People with obvious astigmatism also have similar symptoms, which are eliminated after wearing glasses. Therefore, whether it is myopia, hyperopia or astigmatism, you should always wear glasses.
Many myopia patients have heard that wearing glasses often will aggravate myopia, and the degree will get deeper and deeper, instead of wearing glasses often. In fact, this statement and practice is wrong. People suffering from myopia can't see distant objects clearly because the parallel light entering the eyes is focused in front of the retina. If you put on a pair of suitable glasses, you can move the image of the retina backwards and just fall on the retina, so that you can see things in the distance clearly and have less chance of causing eye fatigue.
After people with myopia wear glasses, the degree of myopia will generally not deepen, because whether myopia is aggravated has nothing to do with glasses (except those who don't wear glasses according to the degree). Some patients wear glasses for a while and don't wear them for a while, which is also easy to cause eye fatigue and aggravate myopia.
