Farsightedness is mainly due to the short eye axis, the imaging falls behind the retina and does not form a clear image on the retina. Whether or not it can be recovered needs to be looked at differently. If it is physiological hyperopia or pseudohyperopia, it can usually be recovered. If the farsightedness is caused by genetic or pathological factors, or elderly farsightedness, it usually cannot be recovered. Physiological hyperopia: The anterior and posterior diameters of the eyes are relatively short at birth, so many young children show a kind of physiological hyperopia, but the eye axis will gradually develop normally with age, and will develop into orthopia or near orthopia in adulthood. However, children with high hyperopia may develop amblyopia before the age of six if they are not corrected in time. This group of people can be detected early through examination, and complete correction and appropriate visual training can achieve good treatment effect. 2. pseudohyperopia: pseudohyperopia caused by visual fatigue, after active intervention, it is possible to recover to normal vision. 2. Unrecoverable: 1. Hyperopia caused by genetic or pathological factors: genetic or external influences lead to impaired development of the eye axis, which cannot reach the normal length of hyperopia; or intraocular masses, orbital masses, etc., which can affect the length of the anterior and posterior diameter of the eye and thus lead to hyperopia. For this type of hyperopia is often not recoverable, mainly through optical lens correction, but also through surgical treatment; 2, elderly hyperopia: that is, presbyopia, many patients with mild hyperopia are relatively young, can use the adjustment of the eye itself, thus showing and normal vision is not very different, can not be given special treatment. However, as the adjustment power decreases with age, the symptoms of farsightedness will become prominent and cannot be recovered on their own, so they need to seek timely medical attention. Commonly used methods of correcting hyperopia are glasses, such as frames or contact lenses, to correct hyperopia. In addition, laser surgery is also available, but is not usually the preferred treatment.
