Spectacle Correction for Myopia
Myopia, or nearsightedness, is a common vision problem that affects a large number of people. The condition has become quite prevalent over the years. According to a study by the National eye Institute, the cases of myopia have grown from 25% in 1972 to 41.6% of the US population as of 2004.
Signs of Myopia
The most telling sign that one has myopia is the difficulty to see distant objects clearly. Other common signs of the condition include headaches, eye strain and squinting. A regular eye examination by an optometrist ensures that the condition is detected early enough and the appropriate treatment administered.
How does myopia affect vision?
Myopia is a condition that arises when light rays being focused in front of the retina, as opposed to on the retina’s surface, as is the case for normal vision. This makes it quite difficult to see objects that are distant. However, people with myopia are able to see well objects that are close.
Myopia affects various aspects of one’s life. For those in school, myopia may make it difficult to view the whiteboard. For those driving, it is difficult to see road signs without vision correction.
There are various treatment options for myopia. The most common ones include eye glasses, contact lenses, laser procedures and other refractive surgery procedures. The most widely preferred form of treatment is eye glasses.
Spectacle Correction for Myopia
Glasses for correction of myopia consist of Single vision, bifocal or multifocal lenses fixed onto spectacle frames. Single vision lenses are simple and provide a full field. These lenses work by providing proper distance prescription for distant objects. In the cases of bifocal or progressive lenses the lower part of the lens will also provide the near prescription to aid in viewing near objects such as when reading or using a computer.
Bifocal lenses are lenses that contain two lens powers on a single lens. This helps the user see objects at all distances. Bifocal and progressive lenses are typically prescribed to those with presbyopia and also have other refractive errors such as Myopia. The diagnosis of presbyopia and the recommendation of this lens treatment option is typically seen in patients 40 years of age and above.
For those who find eye glasses to be cumbersome to live with, contact lenses could potentially be a viable alternative for the right candidate.
