Hypermetropia is a visual focus error which causes difficulty in seeing objects close-up, while distant objects can be seen without any problems. In cases of hypermetropia, the image is focused behind the retina and not directly on it.
The existence of a reduced longitudinal diameter, or the poor focal ability of the cornea and lens, are some of the more frequent causes of hypermetropia.
Most children are born with hypermetropia (around +2.5). However, with time, and over a period of growth, this visual defect tends to correct itself, given that infants learn to regulate focal power through the contraction or relaxation of the eye muscles. If visual focus is not properly corrected after infancy, the adult will suffer from hypermetropia.
