Hyperopia (Long Sightedness)
If the eye is shorter than usual or the lens is weaker than normal, the result is that the image instead of being focused onto the retina is instead focused behind the retina.
This condition results in all objects being out of focus, particularly near objects. Thus long sighted people can see better in the distance but struggle to see near objects.
In reality, a young person can mask this condition to some extent by unconsciously accommodating (re-focusing with their lens) but this results in less accomodating ability, thus presbyopia occurs at a younger age. If the degree of hyperopia is large, then nothing, near or far is in focus and glasses are required full time.
The problem is made worse once presbyopia sets in with age.
