These Three Signs Show That Your Vision Is Slowly Diminishing!
Myopia does not develop all at once. Many children wait until they can't see the blackboard to tell their parents. In fact, it is already too late. There are three signs of vision diminishing. These three signs should be taken seriously.
1 Eye fatigue
when some senior elementary or middle school students study for a long time, their sights will overlap in series, and when they look up at the objects in front of them, they feel like they are separated and floating. There will be a brief blur in front of their eyes after some people move their vision to a nearby object after telephoto or move their vision to a distant object after looking closer. These are all manifestations of the failure of eye ciliary muscle adjustment and are caused by eye fatigue. At this time, although the child's eyesight feels good, the myopic demon is already sneaking in.
2 Hypersensitivity
With eye fatigue occurs, many people are also accompanied by burning, itching, dryness, and pain in the eyes. In severe cases, the pain spreads to the deep part of the orbit, and even causes migraine. It can also cause soreness in the occiput, neck, shoulders and back. It is caused by fatigue and hypersensitivity in the sensory nerves of the eyes
3 Systemic neurological disorders
It turns out that children with good grades will become bored with learning, lack of concentration when attending classes, and have a slow response, become irritable, lack interest in things they originally liked, and decline in academic performance. These changes are also information that myopia is about to occur.
The above three points are called "prodromal myopia syndrome" in the field of ophthalmology. It can be seen that the first thing that appears before myopia is not the decrease in vision, but the symptoms of the nervous system. Myopia is not just a problem of the eyes, but is closely related to changes in the whole body. The following methods can effectively relieve visual fatigue, hurry up and learn!
1. Learn to make your eyes work and rest together
When eye discomfort occurs, closing your eyes and resting is a good way to eliminate eye fatigue.
Generally speaking, after using your eyes for half an hour, you should close your eyes or look at trees in the distance for five minutes to allow your eyes to fully rest.
2. Choose the right light source while studying
A light source with soft light and moderate brightness is the best "partner" for exam preparation. When the ambient light is not good (too bright or too dark), especially in the study, work and living environment with high eye intensity, the brightness of the light is not suitable, the light distribution in the field of view is uneven or flickering, there is reflection or glare, It is easy to cause visual fatigue.
Therefore, for indoor lighting, light sources with softer light and moderate brightness should be used as much as possible.
3. Choosing the best "eye protection" food
Vitamin B is one of the nutritional sources of the optic nerve. Insufficient intake can easily cause eye fatigue, so you can eat more foods such as sesame, soybeans, fresh milk, and wheat germ.
Vitamin A is the most beneficial to the eyes. Vitamin A is an essential nutrient to prevent dry eyes, vision loss, and night blindness; Lutein is the main component of the macula of the fundus, and it is generally found in green vegetables. Eating more fresh green vegetables and supplementing nutrients can effectively relieve visual fatigue.
