The left and right eyes of the glasses have different clarity

More and more people are wearing glasses, especially primary school students. The number of people suffering from myopia increases rapidly every year, which is related to many factors. When myopia occurs, you should wear glasses in time and correct bad study habits in time. However, you must be careful to choose a regular institution when fitting glasses. If the left and right eyes do not see the same clarity as the glasses, you must completely replace the lenses. If the prescription is not suitable, it will aggravate the loss of vision.

There are three reasons

1. The actual power of the lens is inconsistent with the prescription. This is unavoidable when grinding the lens. There is a national standard for reference. You can go back to the optical shop and ask to use a lens meter to check the power, and then compare it with the national standard displayed in their store to see if it is within the reference range.

2 is the problem of optometry. There are two situations. One is that the actual refractive power of your left eye is 5.75, but after you reduced it by 0.25, the stimulation to the retinal cells is not as strong as that of the right eye. This condition is based on the fact that the actual power of your right eye is 4.75, but you chose 5.00. In this case, the optometrist did not perform a binocular vision balance check in the final stage of optometry, or made an error in the binocular vision balance check. Second, your eyes have slight astigmatism, especially your left eye.

3. The optometrist who examined your eyes is basically a beginner. The actual degree of your right eye is 4.75, but they took it as 5.00, which is used for your daily study. The degree of your left eye is obviously 5.75, but they took it as 5.50. He doesn't even know the basic principles of myopia correction, which leads to this result.

1. Some things to note when wearing glasses

First, check

To determine whether you should wear glasses, you should ask a professional ophthalmologist to check. You can go to an ophthalmologist to check your glasses to see whether you have true myopia or false myopia. Only people with true myopia are suitable for wearing glasses. False myopia may be recovered with more attention, so there is no need to rush to wear glasses.

Second, the size of the glasses

Before getting glasses, we must first choose the glasses we like, but not all beautiful glasses are suitable for us. When choosing glasses, we should choose those that are comfortable to wear, especially choosing glasses of the right size according to the size of our face, so that the pupils of both eyes can be in the center of the lenses.

Third, optometry

One thing you must do when getting glasses is to have your eyes tested. An optometrist can use a machine to detect your eye power and pupil distance. With these data, the glasses you get will be accurate. If you don't have your eyes tested, inaccurate pupil distance will make the glasses you get a headache to wear, which is harmful rather than beneficial to your eyes.
