Explaining Nearsightedness

Filed under: Helpful Stuff and Life Of Health and Misc Stuff at 8:04 pm Comments Off

Shortsightedness is when the eyes focus incorrectly, making out-of-the-way objects appear blurred.

A shortsighted person sees near targets clearly, while objects in the distance are hazy. Therefore, someone with shortsightedness tends to squint when viewing far away targets. This characteristic is the cornerstone of the word “myopia,” which comes from two Greek words: myein, meaning shut, and ops, meaning eye.

A shortsighted individual can easily read the Jaeger eye chart (the chart for near reading), but finds the Snellen eye chart (the chart for distance) problematic to read. This cloudy vision results when the visual image is focused in front of the retina, rather than directly on it.

It occurs when the physical length of the eye is greater than the optical length. For this reason, Shortsightedness often develops in the rapidly growing school-aged child or teenager, and progresses during the growth years, requiring frequent modifications in glasses or contact lenses. It usually stops progressing as growth is completed in the early twenties.

Generally, people with Shortsightedness will have a family history of the disease and are likely to develop the condition. If the condition develops, then the most likely outcome will be a healthy normal eye in the mid tweties. Sometimes, there are a few patients who suffer from a retinal detachment.

If you are shortsighted, then you are likely to need to the local opticians and see whether I could get bargain-priced spectacles online. Just go to an actual optician for the prescription and request a copy of the prescriptions.
