Myopia is another name for nearsightedness. This means that you can see objects up-close, but you cannot see them at a distance. A refractive error in the eye causes the patient to seek out optical lens in Huntsville, AL.
Causes for Nearsightedness
The cause of myopia is often due to genetics. Therefore, if your parent wore optical lens that were adjusted for nearsightedness, chances are you will, too. There is also some evidence that suggests that an increased workload may cause the eye condition, as well. It may also be caused by repeated work that entails looking at objects very closely, such as those involved with reading, sewing, or typing. Other causes for myopia are linked to being born premature and at a low birth rate, or having an eye condition where the eyes grow bigger than normal.
Optical lens for myopia often are made for children when they are between eight and twelve years of age. The condition may worsen as the child grows, or when he or she becomes a teen. Between the ages of 20 and 40, most people experience little change in their vision. However, after the age of 40, the vision may start to deteriorate again. The onset of myopia then may be gradual or rapid and sudden. Each case is unique.
The first signs of nearsightedness may surface when a child has difficulties reading a chalkboard at school. He may not see the teacher very well, but have no problems reading his textbook. Other signs may reveal themselves when the patient cannot distinctly see the TV screen or has problems at night while driving. Needless to say, it is important to have your child tested for myopia as there can be social and academic ramifications.
Besides optical lens, patients may also opt for orthokeratology, or corneal refractive therapy. This process involves the reshaping of the cornea. Laser eye surgery is also a possibility. Refer to your options at sites, such as the Specs of Madison, on the Internet. Then make an appointment for a consultation.
