Although myopia cannot see far away and presbyopia cannot see near, the two are very different refractive states. Therefore, even if you have presbyopia and myopia at the same time, they do not cancel each other out. Myopia is a condition in which parallel light rays are focused in front of the retina after passing through the refractive system of the eye, making it blurry to see at a distance. Presbyopia, on the other hand, is a degenerative disease, mainly due to the hardening of the lens, which leads to a decrease in the eye’s ability to adjust, making near vision more difficult to read at close range and putting things farther away to see clearly. The refractive states of the two are different, and one cannot assume that they can cancel each other out just from the fact that one sees blurry at a distance and one sees blurry up close. People who suffer from myopia may also suffer from presbyopia. These two vision problems can exist at the same time, and at this time two pairs of glasses should be worn, one pair of presbyopic glasses and one pair of nearsighted glasses.
