The inability to see things clearly when they are at a distance is called myopia, more commonly known as near sightedness. People who are nearsighted have trouble with tasks like reading highway signs or the blackboard. Myopia is hereditary, and usually appears early in childhood. It is most often treated with corrective lenses, either spectacles or contact lenses. In a prescription for corrective lenses, a lens meant to correct nearsightedness will have a negative number, and the higher the number the stronger the correction provided.

Approximately 30% of the population is nearsighted. If you find that objects that are near to you appear clear, but objects that are at a distance seem blurred, you may be nearsighted. If you have frequent headaches and eyestrain even when wearing your glasses, you should have your vision re-evaluated to be sure that your prescription is still adequate for your needs.

Recent years have seen some interesting and hopeful advances in the treatment of myopia. Refractive surgery using lasers has become increasingly common. Some of the more common of those procedures include Lasik surgery and PRK surgery. In both of these treatments a special laser scalpel is used to reshape the cornea in order to focus light properly on the retina.

Another area that’s being explored with considerable success is reshaping the cornea using contact lenses. Known as orthokeratology, the process involves wearing specially made contact lenses that gradually reshape your cornea so that when you remove them, your cornea temporarily retains the new shape, giving you clear vision without the contact lenses in place. In a similar treatment, called corneal refractive therapy which was approved in 2002, corneal shaping lenses are worn at night and offer clear vision without contact lenses during the day.
