Do you know these facts and myths about eye care? Test yourself with the following True or False statements and see how much you know about your eyes.
Reading in dim light will hurt your eyes
Using the eyes in dim light does not damage them. It wasn’t too long ago that all nighttime reading and sewing was done by candlelight or with gas or kerosene lamps. Everyone should use good lighting, however, to make reading easier.
Not using the proper glasses will hurt your eyes
Glasses are simply aids to improve vision. Going without glasses or lacking proper glasses will not physically damage your eyes. Eyes are neither strengthened nor weakened by glasses. Wearing glasses at an early age will not worsen eyesight. The one exception is in children with crossed eyes (strabismus) or lazy eye (amblyopia), where glasses may straighten the eyes and preserve vision. While it is desirable to have corrective glasses or contacts to provide optimum vision, we should never fear loss of vision for lack of proper glasses. Furthermore, using your eyes will not damage them, whether or not you are wearing your glasses.
Using computers will not damage your eyes
Using computers or video display terminals (VDTs) will not harm your eyes. However, eye strain or fatigue may develop with prolonged periods of close work or reading. Taking breaks and looking up or across the room at frequent intervals usually relieves the strain. If your vision blurs or your eyes tire easily you should have your eyes examined by an ophthalmologist.
Children usually outgrow crossed eyes
Real crossing of the eyes in children is not outgrown. Some children have a wide bridge of the nose which makes the eyes look crossed, but this facial appearance of crossing can improve with age. To avoid seeing double, a child whose eyes are really crossed will use only one eye at a time. The unused or crossed eye may never develop good vision unless the child is forced to use it, usually by patching of the good eye. Crossed eyes may be straightened by glasses, eye drops, or surgery. In general, the earlier crossed eyes are treated the better. Children who appear to have crossed eyes should be examined by an ophthalmologist.
Eye trouble is the cause of reading disability (dyslexia)
Reading problems are often referred to as dyslexia. There is no scientific evidence that eye trouble causes dyslexia, or that eye exercises cure dyslexia. Dyslexia is a learning disorder, not an eye problem.
Sitting close to the television can be normal
Children have a greater ability to focus up close without strain than do adults. They often develop habits of holding reading material close to their eyes or sitting close to the television. There is no evidence that this damages the eyes, and these habits will usually change as the children grow older. Occasionally, children with nearsightedness (myopia) sit close to the television to enable them to see images more clearly. An ophthalmologist can diagnose this condition which is correctable with glasses.
Eating carrots will improve your vision
It is true that carrots are rich in Vitamin A, which is essential for sight; however, many other foods also contain Vitamin A. Only a small amount is necessary for vision. A well-balanced diet, with or without carrots, provides all the nutrients necessary for good vision. Excessive doses of Vitamin A, D, or E may even be harmful.
