With hyperopia, the closer an object is to the eye the more difficult it is for the eye to maintain clear focus. Because the eye is excessively short, light comes to a focus “after” it hits the retina causing a blurry image.
With low amounts of hyperopia in a young person (which is normal and common), this blur is easily overcome by using the eye’s internal auto-focus. This happens automatically, so often people with hyperopia are completely unaware of their condition.
Larger amounts of hyperopia, not easily overcome, can cause symptoms such as blurry vision up close, eye strain and fatigue, and the sensation of words swimming or moving on the page.
As the eye ages, the internal lens becomes less and less able to focus effectively and blur at near becomes more and more apparent. This aging process occurs very gradually until around age 40-50 when reading glasses first become necessary to artificially compensate. This condition is called presbyopia.
Finally, a common type of strabismus (eye turn) is associated with hyperopia. In this condition, accommodative esotropia, lenses are first prescribed to correct the hyperopia which often helps to eliminate the eye turn.
