The first symptoms of hypermetropia, or long-sightedness, include difficulty focusing on nearby objects, according to WedMD. If these symptoms go uncorrected, patients may also suffer headache and eye strain and have trouble focusing on tasks such as reading.
Hypermetropia is caused because the eyeball is too short or does not focus properly, and the image falls behind the retina instead of precisely on it, says WebMD. A person who believes he has hypermetropia can have the condition easily diagnosed in an eye doctor's office, and corrected by glasses or contact lenses. These devices have lenses that bend the light so that the image focuses precisely on the retina.
Many children are born with hypermetropia, according to WebMD. The condition usually improves as the child ages, and if the condition is mild, the child's eye muscles are strong enough to compensate for it. However, adults with hypermetropia might find that even their distant vision worsens with age.
Some people do not want the inconvenience of glasses or contact lenses, and opt for refractive surgery, claims WebMD. These surgeries are either LASIK, which is laser-assisted in situ keratomileusis, or PRK, which is photorefractive keratectomy. Both of these surgeries use a laser to sculpt the cornea and improve vision.
