Hypermetropia/Hyperopia or Farsightedness is a type of vision in which seeing is clearer at far distances than at near. When the eye is relaxed, the combined powers of its optical elements is not enough to bring things into focus.
This is because the image of an object falls behind the retina, and is thus, out of focus. The cause of hyperopia is either the length of the eyeball is too short, or the power of the cornea is too weak. If a person has good focusing ability or just a little hyperopia, he may be able to maintain both clear distance and clear near vision. If, on the other hand, a person has poor focusing ability or a high amount of hyperopia, he cannot focus efficiently even for far vision. This person’s vision will be blurred for both distance and near, although greater for near. The hyperopic patient will have even more problems with near as he becomes presbyopic.
Plus lenses are used to correct hyperopia. It brings the image of an object forward, focusing on the retina, resulting in clear vision. In Asia, there are less hyperopes than there are myopes.

Thanks for this useful and informative post. I have had hypermetropia for about 2 years now. Got it due to an eye problem.
My developer is trying to persuade me to move to .net from PHP. I have always disliked the idea because of the costs. But he’s tryiong none the less. I’ve been using Movable-type on a number of websites for about a year and am anxious about switching to another platform. I have heard fantastic things about blogengine.net. Is there a way I can import all my wordpress posts into it? Any kind of help would be really appreciated!
Great post but I was wondering if you could write a litte more on this subject? I’d be very grateful if you could elaborate a little bit further. Thank you!
