Is glasses myopia more than 400 or more than 500?

Team of Ophthalmology Specialists:

This needs to be considered as a whole, whether it is the brightness of the environment or the TV display. Myopia patients will wear glasses with a lower prescription in order to allow their eyes to self-adjust.

In addition, the experts of our institute would like to remind you that it is best not to wear your glasses indiscriminately, because in the long run, your myopia will be higher than his.

Friend, you have different myopia degrees in both eyes, and it is obvious that the right eye does not have enough power or has astigmatism that is not correct. If you don't feel dizzy at 550 degrees while wearing your classmate's glasses, it doesn't mean anything, if you feel very comfortable, it means that the degree is close.

It is recommended to re-optometry and glasses! Ask the optometrist to find out your primary and secondary eyes, and then prescribe objective prescription glasses based on the results!

Don't worry, it doesn't have to be 550 degrees for you. Although I am not nearsighted, I don't feel dizzy when I wear many of my classmates' glasses, because I haven't worn my classmates' glasses for a long time. The prescription of the two eyes is not the same in general, maybe your right eye has a deeper prescription, it is recommended to do regular check-ups at a good optical store and change into glasses that suit you.

Myopia glasses with more than 400 degrees do not need to be so expensive.

On the basis of correcting bad eye habits, we must reasonably arrange work and rest, and achieve a combination of work and rest. It is necessary to arrange work and rest reasonably, so as to ensure that children have sufficient sleep time, and at the same time, it also prevents long-term eye use, which can prevent the vision from continuing to deteriorate.

Proper participation in sports can speed up the blood circulation around the eyeball, and improve the adjustment flexibility of the eye muscles. Especially when playing sports such as ball games, the line of sight will follow the movement of objects at different distances, which can prevent further deterioration of vision. <>

It should be noted that if the myopia degree is within 300 degrees, it is not recommended to wear glasses if it does not affect the vision. Instead, you should actively go to myopia, control or reduce the degree of myopia, and avoid glasses.

Myopia is a type of refractive error. When the eye is in a relaxed state of accommodation, parallel light rays enter the eye and focus in front of the retina, which causes a clear image to be formed on the retina, which is called myopia. At this time, the refraction examination will indicate the degree of myopia, for example, it is usually called 50 degrees of myopia, and the record of Chunzhen is".

In the state of relaxation of eye accommodation, the external parallel light enters the eye, and its focus falls on the retina, forming a clear image, which is called emmetropia; If the focus does not fall on the retina, it is called nonemmetropia, which is refractive error.

It is difficult to proportionate the degree of myopia and the naked eye vision, and it is related to personal adjustment, and the naked eye vision of 400 degrees of myopia is generally not reached, that is, it is impossible to see the direction of the opening of the largest letter on the eye chart, but most of them can be seen clearly after adjustment.

Under normal circumstances, depending on where you configure glasses, if you prepare glasses for 200-300 yuan in first-tier cities, it must be of insufficient quality and grade, and if you treat them differently in third-tier cities! Hope it helps.

Hello, thank you for your inquiry, the main differences are: the brand of lenses, refractive index and grinding process are different; The brand of the frame and the material used are different. Under normal circumstances, depending on what you are selling glasses, if you are in the first-tier city to prepare 200-300 yuan lack of stool glasses, it must be the quality and grade is not enough, if in the third-tier city that the Vona travel sample is treated differently!

Hope it helps.

I didn't dare to say that my child's glasses were broken, so I bought a counterfeit one for 10 yuan.

If it hurts, it will hurt the glasses and need to be re-fitted.

If you wear it for a long time, it will affect your eyesight weight gain, you can rematch one, he said that you can see the same, this is afraid that you will blame him, a frame is more than 10 yuan, not to mention the lenses, staying for a long time will affect the aggravation of vision.

And he countered that the store is expensive, and the online is cheap.

If a glasses are equipped with regret lenses, the cheapest minimum He Ran is more than 100, and the degree is still not high, if the lens with a high prescription will be very expensive, and the glasses frame is not expensive.

I also told him this, and he was already wearing two fake ones before I found out.

Therefore, in order not to affect the aggravation of the child's eyesight, I also want to go to the regular optical store again to get a pair of glasses suitable for the child.

Good. En.
