why eye glasses actually worsen your vision

While it is true that eyeglasses bring some people improve vision and relief from pain and discomfort,they always do more or less harm, and at there best they never improve your vision to normal.
most people don't realize that there visual are abnormalities are a dynamic process that they vary regularly throughout the day due to the variety of conditions. they simply are not set in stone.
If we take exam then it is sure that more than half of the student or people  have a normal eyes with sight has perfect visions. And we will find better vision of some one else, but it is not for ever and it may damage with our simple mistake and even if we wear glasses it increase our glasses power. Even some people have perfect their sight in the morning and imperfect in the evening.
The degree of imperfect sight varied within wide limits. Its duration was also variable.Under some condition it may continue for only a few minutes or less while under other it might prevent the subject from seeing the blackboard for days, weeks or even longer.
the difficult of keeping glasses clear is one of the discomforts of glasses.. On damp and rainy days the atmosphere cloud them. On hot days the perspiration of your body may have a similar effect.

One of the most foundational flaws with glasses is that they provide unchanging consistent correction for the refractive error in your eye that is constantly changing.
after you begin to wear, in most cases the correction has to be steadily increase in order to maintain the degree of  visual actually secure by the aid of the first year.Your vision wearing glasses progressively decrease with time.
A person with myopia of 20/70 who put glasses giving him a vision of 20/20 may find that in a week's that his unaided vision has declined to 20/200.
When people break their glasses and go without them for a week or two, they frequently observe that their sight has improve. As a matter of fact the sight always improves, to a greater or less degree. When glasses are discarded, although many might no pay attention and appreciate this change.
the difficult of keeping glasses clear is one of the discomforts of glasses..On damps and rainy days the atmosphere cloud them. On hot days the perspiration from your body may have similar effect. On cold day they are often clouded by the moisture of your breath.
 Every day they are subject to contamination by dust and moisture and the touch of the finger incident to unavoidable handling that it is seldom they afford an absolutely unobstructed 











what is myopia?




Myopia is commonly known as "short-sightedness." A person with myopia is able to see close object clearly but objects in distance will appear blurred.












When normal eye look at an object, light rays from your eye enter our eye. These light rays are bent at the cornea and the eye lens before forming an image on the inner layer of the eye called retina. This image is than transmitted by nerve signal to the brain. The brain interprets this signal so that we see the object.
if the light ray are focus directly on the retina, we see a sharp image. Therefore, myopia may occurs when the light ray from distant objects are focus in front of the retina instead of on it, resulting in blurred image on the  retina. This is usually because the eyeball is too long or sometimes the cornea and the lens do not bent the light ray properly.

cause of myopia

There are many region for cause of myopia. If we do hard work by focusing our eye more close, and if we do not relax our eye at that time, then it may cause myopia.(e.g reading )
Watching more TV from close distant may also occurs myopia.
Because of the differ in light such as dim and bright, while working and reading.
lacks of eye exercises and relax.
lacks of nutrients foods.
