In children younger than 3 may appear physiological farsightedness but with growth of the eyeball it should fade (eyes should undergo an emmetropization process, meaning the improvement of the farsightedness and return to a state without the defect). If this does not happen and the defect does not disappear, it will be necessary to provide correction. Estimates state that about 90% of the youngest children are farsighted and this percentage decreases to about 40-50% of children between the ages of 8-10.
With attention on the possible accommodations this condition can easily not be diagnosed for some time. Parents should give their attention to symptoms like lack of desire to read and peruse a book, quick tiring of the eye or squinting. This last symptom appears when, i.e. the defect in both eyes differ or when one eyeball is characterized by the underdevelopment of the optic nerve. The weaker eye stops working and disconnects in the vision process, because the brain “chooses for itself” monovision, the more efficient, better seeing eye. We can then observe the wavering of one eye. A quick visit to the ophthalmologist is necessary, because the situation can lead to disturbances of binocular and/or spatial vision (stereopsis). In the event of strabismus, the faster the ophthalmologist’s intervention, the greater the chance of avoiding monocular vision (seeing with only one eye), which in the future may result in the inability to work in several professions (i.e. driving).
Between the ages of 25 and 40, a typical symptom of farsightedness is worse vision up close. After 40 years of age, farsightedness manifests itself by poor vision both at a distance and up close (due to poor accommodation). A separate eye problem is the so-called farsighted presbyopia (or simply presbyopia), which is not technically a vision defect, but a set of changes that occur with age in the human eye. It can also appear in people who have been diagnosed with any vision defects.
