Farsightedness is a defect in vision, otherwise known as refractive error, or even ametropia. It is more precisely a disorder of accommodation.
Hyperopia is linked to an insufficient axial length of the eye. It is said that the eye is "too short". As a result, the perceived image is formed behind the retina instead of forming on the retina. Thus, the eye sees badly closely and the images are blurry. On the other hand, far vision is correct most often. It's the opposite of myopia.
The degree of anomaly of the vision is measured in dioptres, it is a unit of value of a defect of the vision; its value is a function of the importance of the defect to be corrected, the corrective lenses of the prescribed glasses will have a power corresponding to the number of diopters necessary for him to see the best possible.
Hyperopia is very common. It is even quasi-systematic in young children. Then, with growth, vision can normalize. However, when it is greater than +2 diopters, the view of the child must be corrected.
Hyperopia is the most common refractive disorder of children. It requires early detection and adequate management given the risk of developing into strabismus or amblyopia (vision loss without organic lesions).
