Is presbyopic hyperopia

presbyopic is not hyperopia, it is two different refractive states. presbyopic is also called presbyopia, is due to the increase in the hardness of the lens after age, so the eye's ability to adjust decreased, symptoms normal performance for the decline in myopia, see near very blurred, see far vision is normal, this situation is a degenerative change, so in the elderly more common. Hyperopia is a refractive error, because the refractive state of the eye is lower than the normal range, so the object image formed by parallel light from the outside will fall behind the retina, which will cause both far and near vision to decline. Therefore, this is two completely different refractive states. Presbyopia can be improved by wearing presbyopic glasses, but it does not need to be worn for a long time. It is only worn when reading at close range. Hyperopia requires wearing glasses for a long time, and it requires wearing glasses for a long time.
