Myopia in one eye is basically the same as the usual principle of correction for myopia in both eyes. If the difference between the two is not large, the normal eye can be equipped with plano lenses, 250 degrees or less, and the other eye can be equipped with myopic lenses, or contact lenses can be worn. As an adult, you can also have myopia surgery, both of which are methods of correction. For people with more than 250 diopters, it may not be comfortable to wear frames, because the difference between the two diopters is quite large, and the magnification of the object may not be the same. So, taking that into consideration, frames may not be as appropriate as contact lenses, or other surgical methods of correction. Depending on the age and the amount of difference between the two, a decision will be made as to which method of correction is more appropriate.
