Also known as nearsightedness, myopia is an eye condition that causes blurred vision of distant objects, whereas the near objects appear clear. People suffering from this problem have difficulty in watching road sign boards, movies on television, etc., and children have difficulty in clearly looking onto the white board. It is a hereditary disorder and is usually transmitted from parents to offspring. Other reasons can also be the excessive use of eye muscles, for example reading books, too much working on the computer or prolonged periods of other close eye works. People with the predisposition of this disorder develop it as a result of excessive use of eye muscles in close eye works.
Myopia is caused when a person has or develops, an eyeball too long as compared to the original size. This distorts the refraction of light, causing it to focus at some point in front of the retina, rather than focusing on it. It can also be caused due to the irregular curvature of cornea or lens in comparison to the eyeball. At times it can be a result of all these conditions.
The symptoms are the same as other eye disorders, like a headache, eye strain, squint, pain in muscles of neck and shoulders. In children, these are accompanied with excessive blinking and frequent rubbing of eyes.
Some people experience a condition called night myopia, causing blurred vision during the night time. The reason behind it is the lack of proper light at night that restrains from proper image formation, causing blurred vision. People doing excessive close eye work also develop a pseudo myopia, which disappears after resting the eyes. But constant visual stress can cause it to become permanent. Variations in blood sugar level can also cause this problem as a symptom.
The disorder can be detected only by a detailed eye check up. An ophthalmologist checks and tells the degree of the problem and what treatment method should be adapted. Use of eye glasses and the contact lens is the common and most harmless treatment. Refractive surgery and laser treatment are also other treatment methods but they are not always suitable for every person. The ophthalmologist himself suggests if a person needs to go for any of these options.
The children, as well as the adults, need to have regular eye checkup. It is good to detect any eye problem at the initial stage when it is still easy to be treated. The more a problem is prolonged, there will be more difficulty in treating it.
