Adult patients with refractive error can be intervened with glasses and surgery, but binocular image differences can occur with glasses.
Refractive error is defined as a difference in the number of diopters between the two eyes. If the difference in diopters is more than 250 diopters, when encountering objects with large differences in contrast, size and color, the two eyes will have difficulty in blending and amblyopia will easily progress. Refractive error in adults can be corrected with eyeglasses.
However, the use of eyeglasses for refractive error correction may result in a difference in the size of the image received by both eyes due to the difference in the magnification of the lenses, causing difficulties in image fusion. In general, the greater the difference between the two eyes, the more difficult it will be to visualize.
Therefore, patients with a high difference between the two eyes can be treated with refractive surgery to make the vision of both eyes as close to each other as possible, in order to improve the quality of vision and solve the problem of refractive error.
It is recommended that patients with refractive error should visit the hospital in a timely manner to have their condition evaluated and treated according to the doctor’s instructions.
