The eye with short-sightedness (myopia) is “too long” (measured from the front to the back); in rare cases, the power of the focus of the cornea and the lens is too large. For this reason, images of distant objects are sharpened in front of the retina, and are blurred. However, close objects can be seen clearly. A short-sighted eye cannot correct the blurred images by itsels, as is sometimes the case with long-sightedness.
Short-sightedness is very common and affects about 1 person out of 6. It usually occurs late in childhood and is getting worse until the person reaches age 20. The condition is often hereditary.
What to do?
If you think you have short-sightedness, contact the ophthalmologist. If the tests confirms your suspicion, the ophthalmologist will prescribe you glasses (or contact lenses) with concave lenses. The lenses will “move” the images of distant objects to the retina and thereby sharpen the image.
Short-sightedness usually does not deteriorate to a significant extent after the age of 20; however, every two years, it is still necessary to go to the oculist for the purpose of detecting any changes.
