The difference between presbyopic and hyperopic eyes

There are obvious differences between aging eyes and hyperopia. Aging eyes are the decline of ciliary muscle adjustment ability at a certain age, and the lack of near adjustment function causes unclear near vision, which needs to be corrected by presbyopic glasses with equal degrees. Hyperopia is mainly congenital development, eye axis is relatively short or corneal curvature is relatively flat, resulting in distant images or light imaging behind the retina, but also excessive use of adjustment ability, focusing the image on the retina, hyperopia whether looking far or near need to use adjustment ability, easy to show visual fatigue. At a certain age, you need to use more accommodation, presbyopic also shows faster, aging eyes and presbyopia are completely different concepts, presbyopia also shows presbyopic earlier than normal people.
