Explaining Shortsightedness
Shortsightedness is when the eyes focus incorrectly, making far targets appear smeared.
If you are nearsighted, it means that you will see targets close by (reading a book) perfectly, however you cannot look at an target further away, without the image smearing. So you may find that you squint your eyes to help focus better. As A Matter Of Fact, the technical term for near sightedness orginates from the Greek words that mean shut eye.
A nearsighted individual can easily read the Jaeger eye chart (the chart for near reading), but finds the Snellen eye chart (the chart for distance) tough to read. This obscured vision results when the visual image is focused before of the retina, rather than directly on it.
It occurs when the physical length of the eye is greater than the optical length. So, you see, Nearsightedness often develops in the rapidly growing school-aged child or teenager, and progresses during the growth years, requiring frequent alterations in glasses or contact lenses. It usually stops progressing as growth is completed in the early twenties.
So whilst young people are the most likely to get Myopia. It happens in equal numbers between boys and girls. If there is family history, then somepeople are most likely to have it.
If you are myopic, then you are likely to need to the local opticians and see whether I could get cheap glasses online. Just go to an actual optician for the prescription and request a copy of the prescriptions.
