If one then wants to look at a far distance the picture is first blurred for a brief moment and then becomes clear because it takes time before the lens is relaxed, flat again. The image becomes clear when the lens accommodates, becomes thicker and makes the light rays bend more so they now cross at the retina. In a myopic, near sighted, eye the image of a distant object is in the vitreous and the image at the retinal level is blurred. Accommodation does not make the image clear. The myopic eye sees objects close by clearly.
Hyperopia is very common.
The lens of a hyperopic eye is accommodated some when the eye looks at far distance and it has to be accommodated more when the eye looks at near. If the hyperopic eyes get tired when looking at reading distance the use of reading glasses can be started at any age. Reading glasses are plus lenses, thicker in the middle than at the edge. Myopia cannot be compensated by accommodation. A myopic person sees better at distance when squeezing the eye lids to a narrow opening which functions as an optic slit .
