Posted on: August 19, 2008

Long-sightedness

Long-sightedness (hyperopia) is a common condition that affects the ability to focus on objects which are at short distances. In a long-sighted eye, the light focuses behind the retina, blurring the image. If it is significant, long-sightedness can cause vision problems, headaches and tiredness. Glasses, contact lenses and laser techniques are used to correct long-sightedness.

Short Sightedness

Myopia is another name short sightedness is the most common refractive error, affecting one in five Australians. Myopic patients are nearsighted; they see close objects more clearly, but distant objects are blurry or even indistinguishable. Myopia occurs when the eye is too long or the cornea is too steep. As a result, light rays entering the eye fall in front of the retina instead of directly on it.
