There are many factors in the formation of hyperopia. The more common one is caused by the short axial length of the eye. Generally speaking, in order to see things clearly, whether it is farsighted or near, it is necessary to use Adjustment, so the eyes are more prone to fatigue. Let's take a look at the symptoms of farsightedness. If there is a high degree of hyperopia, even if adjustment is used, if the refractive error cannot be corrected, it will appear that the distance between things is shortened and things are enlarged to make up for the lack of adjustment ability and achieve the purpose of recognition. Therefore, people with high hyperopia will appear. Especially close to things, such as hyperopia will put the book very close to the eyes, folding is a symptom of high hyperopia, also known as 'hyperopic myopia performance'. In general, for mild hyperopia, the adjustment of the ciliary muscle can make up for the insufficiency of refraction, and other visual symptoms will not appear, so many young people are not easy to find even if they have hyperopia. However, because farsightedness requires adjustment not only when looking at a distance, but also when looking at a close distance, the eyes are more prone to visual fatigue, and common symptoms include blurred strength, swelling and pain in the eyeball, orbit and brow arch. , and some people also experience nausea. If the farsighted eye is adjusted for too long, cycloplegia may also occur, resulting in visual impairment. Some hyperopia patients also have good vision in one eye and poor vision in the other eye, mainly because hyperopic patients use too much adjustment, resulting in symptoms of esotropia or esotropia. Young patients also need to use the adjustment of the ciliary muscle. If they are overused, although the refractive power is temporarily relieved, hyperopia is prone to emmetropia or myopia, which is called pseudo-myopia. People with farsightedness generally have a small eyeball and a shallow anterior chamber. And the optic nipple will be smaller, the edge is unclear, slightly unclear and so on. Premature 'eye presbyopia' phenomenon, but also be alert to hyperopia, this is because due to age increases, the adjustment ability of the ciliary muscle declines, both distance and near vision decline, and the near vision loss is more obvious.
