Why are more and more people wearing glasses?

Nowadays, more and more people wear glasses. Although besides myopic, still have the eyesight problem such as farsightedness, strabismus, astigmatism, need will correct through wearing glasses, but in the person that wear glasses mostly still is myopic crowd, in newly added myopic crowd, most is children and teenager.

With respect to current relevant research, although the cause of myopia follows heredity to take off not to leave concern, but, the level that uses an eye, habit, electronic screen kind of product use habit, and the time that attends outdoor activity, also have apparent concern with myopia.

In primary and middle school students in China, there is a widespread problem of overuse of the eyes. They spend too much time studying, reading and using electronic devices, while too little time in outdoor activities. To some extent, this situation has caused more and more children and teenagers to develop myopia.

Myopia is also a disease.

Especially high myopia can bring eyeball a series of pathological change, affect life study and work seriously thereby, hope parents cause to take seriously so, the prevention of myopia without myopia myopia, have used scientific method of myopia, control myopia degree deepen, reduce degree even, avoid development become high myopia.

But most people don't know how and when to wear glasses. Many parents reflect that their children only wear glasses in class, how should glasses wear?

What is the right way to wear glasses after all

The expert expresses, medium above myopic should wear glasses for a long time to correct, prevent degree to deepen, but medium below myopic can choose to wear according to need still not wear. About the problem that wears glasses, some people insist that glasses wore long eye appears to be out of shape to affect aesthetic feeling extremely, and some people hold to glasses for a while pick for a while to wear can let myopia degree deepen, so it is wearing glasses all the time after all, it is better to wear again when still need?

Medium above myopia had better wear glasses all the time!

Moderate above myopic proposal is wearing glasses all the time, such comparison is convenient for life, won't appear a few because of see not clear and the problem that cause, also can avoid to see fatigue and cause myopia degree at the same time sharp deepen. So, how many degrees of myopia is called moderate myopia? Moderate myopia refers to myopia of more than 300 degrees. If myopia of more than 300 degrees, it is recommended to wear glasses all the time.

Glasses are one of the most important tools to correct vision and protect eyes. It is not easy to borrow glasses. It is harmful to wear glasses of others

Wrong refractive, easy to deepen the degree

Eyeglasses are most concerned with the high accuracy of diopter. Diopter is based on the actual strength of each person's eyes. Therefore, the diopter of each pair of glasses is different. Ophthalmologists or optometrists make glasses based on the results of the optometry, so everyone's glasses are specific and the diopter is not the same. If you wear glasses with different diopters, you can see the object clearly temporarily, but it is definitely not clear. If you open your eyes and watch with force, you will see clearly gradually, but that is to artificially strengthen the adjustment effect, and it is easy to produce visual fatigue after a long time. Eyes in this case for a long time, it is easier to deepen the glasses. If borrow wear astigmatism glasses, still can turn healthy eye, artificially become astigmatism sick eye, that is the gain outweighs the loss.

Pupil distance is not accurate, wear troublesome

Pupil distance is one of the main technical parameters for lens matching. Although two people have exactly the same diopter, pupil distance may not be the same. Blindly put on pupil distance and his inconsistent glasses, this kind of practice is very wrong.

Because of the distance deviation, parallel light through the refractive system after inflectional, still can't in the retina to form a clear image, in this way, not only can improve eyesight, instead of depending on the cause of deformation, clarity, increase vision fatigue, causing dry eye, eye bilges, giddy, disgusting, vomiting, memory loss, poor analysis function, seriously affected the work and study, If you break your eyes or your body, why bother to wear someone else's glasses?

The frame is distorted

The frame is an important part of glasses, which is determined according to the size of each person's head. Each person's head is big or small, and the distance between ears and eyes is long or short.If the head is big, borrow the glasses that wear a small head, can loosen lens foot or make lens frame distortion is out of shape, when wearing again so, lens optical center cannot be same as before to pupil, can produce prism effect.

Borrow as small head, wearing big glasses, will slide down, can only wear, extrusion or pull head wearing, and grilled big or long, cause frame torsional friction pressure, make it easy to frame or deformation, and, more importantly, everyone's different distance, too wide, too narrow, too high, too low don't apply, can cause dizziness, headache, vision is not clear, it is not good.

It's easy to catch eye diseases

Eye ministry contagion is healthy main Nemesis, contact contagion is the important way that infects disease more. Infectious germs are everywhere, if you borrow in patients with pink eye glasses, it is easy to the bacteria adhesion on the lens or frame, and the wearer has not cleaned in time, but you will be borrowed to wear glasses, it will spread to the pink eye and other eye diseases, endangering the health of the eyes, and even life-threatening, really have a vile indeed.
