What is Hypermetropia. What Are The Symptoms of Hypermetropia?
Hypermetropia, frequently called far-sightedness, is the opposite from myopia. In this health condition, rays of light are brought to a focus back of the retina. There are normally blurred vision, migraine, and anxious fatigue in attendance upon this form of eyestrain, and always the difficulty in accommodating at the near point.

The so-called far-sighted eye is not, in actual fact, better able to see at a distance than the normal eye. It is simply unable to see the things that are close to it.

It is evident that the person troubled with hypermetropia is extremely unlikely to become the recluse "who always has his nose in a book." Reading over a amount of time causes giddiness, clouding of the vision and typically an inflammation of the eyelids. So this victim of eye-strain becomes the person of action.

There are numerous reasons this can happen. If the eyeball itself is too short, from front to back, then the light rays will not be able to focus on the retina. Conversely the problem may be at the front of the eye with the cornea or lens. If the curving of the cornea is too shallow it will not bend the light rays to the right angle to successfully direct them at the retina, the same is true of the lens if it is too thin.
