If the degrees of two eyes is greatly different, how to choose a glasses? (1)

           Many people have different degrees of difference between the two eyes, which makes the glasses uncomfortable. It is either uncomfortable or double-viewing, or it is particularly easy to fatigue. In short, everyone is very wary about their own optician experience.
But this situation is not caused by a short time, but from the very early days when you started myopia or began visual development, this problem has already formed, and then slowly led to the emergence of serious problems.
         
          The above two eyes are not equal in diopter, let's call it anisometropia.
          Forms include:

1. Binocular myopia, one eye is higher than the other eye, or astigmatism is different.
2. One eye is nearsighted and one eye is normal
3. One eye myopia, one eye hyperopia.
4. Both eyes are farsighted, one is higher than the other.
5. One eye is farsighted and the other eye is normalFor anisometropia, the difference in the degree of binocular power at a lower degree may not cause any problems.

           When the anisometropia is large, the degree of the two eyes is different, the thickness of the lens is different, and the imaging effect and size are different. At this time, if the appropriate correction method is not adopted, the wearing of the frame glasses may be inappropriate.
          Among the problems are: visual fatigue, impaired binocular vision, problems with third-level visual function, double vision, headache, photophobia, nausea, misalignment of spatial sense, abnormal sense of distance, writing and reading, missing words, not lasting, etc. Wait, in short, it is very uncomfortable.
How can we correct it?
            Let's summarize the current correction methods and adaptation populations that can be referenced:

1. Frame glasses:

1) When the degrees of the two eyes are not much different, consider using frame glasses.
2) Frame correction can also be considered when the patient can tolerate the difference in anisometropia between the two eyes.
3) When the patient has produced binocular alternating vision, and the age is too large, consider using
4) When the difference between the two eye degrees and the visual acuity is large, we try to correct the eye with a low degree of vision.
5) When the difference between the two eyes is not large, we can appropriately carry out the excessive program, gradually increase the degree of both eyes, and cooperate with the training to improve tolerance.
6) If there is adult hyperopia with amblyopia or high myopia, poor vision, consider giving up correction, the degree is equal to the level of light or the correction of the other eye.
7) If the two eyes are heterosexual anisometropia, consider the low correction of the two eyes to adapt to the main. If you consider the visual acuity, the eyesight is better.
   
           Next time I will explain other ways to choose you eyeglasses for different degrees of your sight.
