Eye Myths: Fact or Fiction?

Do you have hectic days at this time? Is there any trouble with your eyes since you have spent much time for reading some books or finishing your assignments? If you get any trouble with your vision, did you exercise to make your vision better? Or have your beloved parents or grandparents given much suggestion about your eyes, like “Eat many carrots for your eyes” or “Don’t read in dim light because it can damage your eyes”.
Well, guys… because the eyes are so important for us, the worth makes myths about eye health. The myths are passed from one generation to the next generation, from generation of our grandparents to our generation now. Nevertheless, the myth is important to distinguish between fact and fiction. Therefore, knowledge about eye care is the first step to let your vision healthy for a lifetime. Grewal as Professor and Head, Dept. of Ophthalmology, Dayanand Medical College and Hospital Ludhiana has explained the myths of eyes and distinguished between the fact and the fiction.

1). Eyes can be transplanted
The eye is connected to the brain by the optic nerve (made up of millions of nerve fibers), which cannot be reconnected once it is severed. Hence, there is no way to transplant the whole eye. The eye is never removed from its socket during surgery. Only the cornea, the clear front part of the eye, can be transplanted for conditions where it becomes opaque.

2). Eating carrots will improve your vision
It is true that carrots are high in vitamin A, which is necessary for development of normal vision. There is no indication that overdoing it will improve vision. However, only a small amount is required a good diet with or without carrots, provides plenty of vitamin A.

3). Reading in dim light can damage your eyes
Reading in dim light does not affect vision but the effort required can cause eye fatigue, but will not worsen any refractory error. However, for comfort, the reading material should be adequately illuminated either by daylight or by adequate positioning of the light source.

4). Excessive reading, sewing or doing other close work decreases vision
For hundreds of years, reading or sewing at night was done candlelight, or with gas or kerosene lamps. Good lighting and right glasses make things more comfortable and less stressful but their absence does not decrease vision.

5). People with ‘weak eyes’ should avoid reading fine print
It is a common belief that people who wear glasses have weak ayes and will further harm their eyes if they read fine print or do a lot of detail work. The eyes do not get any sort of damage by reading fine print. Again, adequate comfort should be provided.

6). Excessive crying especially due to bereavement causes decreased vision
Excessive tear formation as in crying is a response to emotion and has no effect on vision. If there is decreased vision, it should never be attributed to excessive crying.

7). Failure to use proper glasses will worsen nearsightedness
Nearsightedness is a hereditary condition in which the eye length becomes longer than normal so that a distant object is not focused on the retina. This myopia increases as the child grows usually up to the age of adolescence irrespective of him using glasses or not. Therefore myopic children should get their eyes checked every year.

8). Eye exercises can remove glasses
Eye exercises can alleviate eye strain due to muscle imbalance. Only any refractive error can only be corrected by glasses or contact lenses.

9). Contact lenses can prevent nearsightedness and myopia from getting worse
Some people think wearing contact lenses will permanently correct nearsightedness and myopia, and eventually they might be able to get rid of their glasses or contact lenses. Contact lenses improve refractory error while yoy are wearing them just as glasses do, but do not reverse the condition or keep it from becoming worse. Myopia progresses up to adolescence after which it stabilizes. So, yearly refraction should be done.

10). Sitting too long or too close to the television or holding a book too close to your eyes is the cause of children wearing glasses

Children can focus up close without eye stain better than adult can. Some children develop the habit of sitting too close to the television or holding a book too close. There is no evidence this practice will decrease their vision, and the habit usually disappear as the child grows older. However, children who have poor distant vision will also tend to sit closer to the television or hold a book too close. Therefore, this may be an early sign and not the cause of decreased vision. Such children should have their eyes tested for any refractive error.
Well, guys…several myths above with the explanation whether it is fact or fiction hopefully can enrich your knowledge about eye care to be the first step in order to let your vision healthy for a lifetime.
