1, the corrected visual acuity after wearing glasses in one eye should be 0.8 to1.0;
2. The corrected binocular vision should be 1.0 to1.2;
3. The corrected vision of both eyes with lenses should be the same, and the degrees can be different;
4. Except for special occupations;
Secondly, whether it is the degree of mydriasis optometry or the degree of computer direct optometry, it can only be used as a reference when fitting glasses. In order to match the most suitable degree, optometry needs to be inserted; A degree that meets the above conditions is the most suitable degree; Glasses should not be high. Once it is too high, it will not only cause dizziness, nausea and other discomfort, but also aggravate the degree of myopia in the long run. Wearing glasses is also very particular, especially for children. You can wear it when looking at the blackboard and farsightedness, but don't wear it when using your eyes at close range, such as reading and writing, otherwise it will aggravate the degree of myopia;
As we know, myopia is caused by parallel light rays from 5 meters away entering the eyeball, and the focus formed after refraction by various refractive media in the eye falls in front of the retina, and a clear object image cannot be formed on the retina. At this time, it is necessary to wear a concave lens and move the focus backward to achieve the purpose of correcting vision. Laser surgery is to change the surface of cornea with excimer laser scalpel, make your cornea thin and make it into the shape of concave lens, which is equivalent to carving your glasses on your cornea. It didn't change the essence of myopia, but let you get rid of the trouble of glasses for a while-your cornea became your glasses; As we know, the cornea has the function of protecting the internal tissues of the eyeball, and its thickness determines its compression resistance; There is liquid in the eyeball, and there is pressure when there is liquid. Normal thickness of cornea is easy to resist this pressure, but what about thinning cornea? What if you can't resist the explosion? The eyeball cannot be replaced; Similarly, everyone has only one pair of eyes and a pair of corneas. Can I shave once? What should I do if I am nearsighted again after the operation? Why does the laser surgery hospital let patients sign a statement of no responsibility? Laser surgery was invented in European countries, and now it has been banned in Europe; In China, it still exists because of the lack of market and related awareness; In Japan, 65,438+10,000 myopia patients who underwent laser surgery were all found to have to undergo corneal transplantation after 10 years. Therefore, if it is not really necessary, patients are generally advised not to do laser surgery; Now there is another operation called intraocular lens implantation, which is to implant an intraocular lens with diopter directly into your eyes instead of glasses. It is better than laser surgery in principle, but it needs a lot of crystals and may not be suitable for everyone. After all, foreign bodies will definitely have compatibility problems when they enter the human body. The cost is also high, and post-maintenance is also a problem; Without changing the essence of myopia, just put your glasses in the eyeball and get rid of the trouble of glasses; In short, if it's not really impossible, wear rimmed glasses. Although a little ugly, it is much safer and cheaper!
Then wearing frame glasses faces two more problems: one is that the more you wear, the faster your vision will decline; Secondly, after a long time, the eyeball will change organically-the axial length will become longer, which shows that the eyeball protrudes outward; Why is this happening? We should return to the principle of myopia, which means that the focus falls in front of the retina, so we can correct our vision by wearing concave lenses and push the focus back to the retina to achieve the purpose of hyperopia; In fact, we don't need to wear glasses when we are near, so the general practice is that it is more convenient to wear glasses when we are near, so this will cause our focus to fall behind the retina when we are near, forming a false hyperopia state, and our eyes are adjustable. In this case, the eyes must be adjusted reversely. Rearrange the focus behind the retina to the retina. After a long time, my eyes are too tired. When we take off our glasses, we will find that our eyesight has dropped again-the center of gravity has moved forward; Moreover, because of wearing glasses for a long time to see things at close range, the focus always falls behind the retina, which will send a wrong message to the brain: my eyes are too short in the front and back axes and always can't catch the focus. Should I stay longer? Therefore, the brains of teenagers in the growth and development period will send the wrong instructions to the eyeballs: a little longer, the cup will break and the eyeballs will protrude!
In the case of your child, first of all, change the previous bad eye habits to prevent myopia from deepening; Secondly, we must pay attention to the method of wearing glasses. If it is not necessary, you should generally wear glasses as little as possible. Then there will definitely be times when you can't see clearly without glasses, so at this time you would rather work harder and look closer than squint and frown; Finally, if you go to a professional vision correction institution in time, your child's vision will return to normal;
I am the manager of Zhuhai Direct Store, a brand operation and management organization of the national franchise chain in the vision correction industry. Our Shining Life Vision Rehabilitation Center adopts an effective "SL vision rehabilitation comprehensive training system", which is based on Dr. Bates' natural balance therapy in the United States and our domestic binocular combination method, and combines the essence of our Chinese nation's 5,000-year Taoist health preservation. The whole training process does not require injections, medicine, massage, surgery, or direct contact with children's eyeballs, and it is safe without any risk or toxic side effects. It is a process of improving children's visual function directly from the inside out through training, and it is a qualitative change caused by quantitative change; According to our past experience, mild myopia can recover to normal vision (1.0) or even reach 2.0 after about 2 courses of treatment. Moderate myopia can return to normal after more than three training courses; Long-term training to treat high myopia can continuously improve naked eye vision, reduce the degree of glasses, and have a good fit. People who insist on serious training for a long time can even restore their normal vision! But we are targeting children under 20; Of course, it doesn't mean that it won't work if you are over 20, but the effect will be relatively poor and it will take longer;
We have dedicated our shining life to the promotion of children's vision rehabilitation technology in China, and sincerely hope that all our children can have a pair of bright eyes and everyone can have wonderful vision; This is our mission, our responsibility and our belief!
