Search About Eye Conditions Image Are there really alligators in the New York City (or Chicago or Minneapolis) sewer system? Did George Washington really chop down that cherry tree? These myths get retold so many times that over the years they assume the status of reality and today many myths are being circulated around the world through the world wide web. Consumers may well have heard or read myths masquerading as facts about their vision. While most are harmless, some misinformation can actually be damaging if people believe it. Take this little test to see how your own understanding of some widely circulated "facts" stacks up to the truth. 

Myth 1: Reading in dim light will hurt your eyes. 
[_] True [_] False

Using the eyes in dim light does not damage them. It wasn't too long ago that all nighttime reading and sewing were done by candlelight or with gas or kerosene lamps. Everyone should use good lighting, however, to make reading easier and to prevent eye fatigue. So the correct answer is False. 

Myth 2: Not using the proper glasses will hurt my eyes. 
[_] True [_] False

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 contact lenses 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. The answer to this question is False. 
However, even though the wrong lenses may not damage the eye physically, we all know the dangers to other parts of the anatomy when the wrong eyewear results in a fall or misjudgment of distance. 

Myth 3: Using computers will not damage your eyes. 
[_] True [_] False

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. Special lens tints can help also. If your vision blurs or your eyes tire easily, you should have your eyes examined. Correct answer to this question is True. 

Myth 4: Children usually outgrow crossed eyes. 
[_] True [_] False

Children do not outgrow real crossing of the eyes. Some children have a wide bridge which makes the eyes look crossed, and this facial appearance of crossing can improve with age. To avoid seeing double, a child with true crossed eyes will use only one eye at a time. The unused eye may never develop good vision unless the child is forced to use it, usually by patching 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 a doctor. Correct answer to this question is False. 

Myth 5: Eye trouble is the cause of reading disability (dyslexia). 
[_] True [_] False

Reading problems among children 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. However, it is extremely important that dyslexic individuals who have vision problems get corrective eyewear so they can take full advantage of special training designed to overcome the learning disability. Correct answer to this question is False. 

Myth 6: Sitting close to the television can be normal. 
[_] True [_] False

Children have a greater ability to focus up close without strain than adults do. They often develop habits of holding reading material close to their eyes or sitting close to the television. There is no evidence that sitting close to the TV set damages the eyes. Occasionally, children with myopia sit close to the TV and these children do need to be examined by a doctor so they can have corrective eyeglasses or contact lenses. Answer to this question is True. 

Myth 7: Eating carrots will improve my vision. 
[_] True [_] False

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 Vitamins A, D, or E may even be harmful. Correct answer is False. 

Myth 8: People with weak eyes should avoid reading fine print. 
[_] True [_] False

There are many misconceptions that people with weak eyes, or older people who have trouble seeing should not use their eyes too much for fear of wearing them out sooner. There is also a fear that looking at fine print may accelerate vision loss. Using our vision to its fullest to see fine print or details in a drawing or photograph will not wear out our eyes. The correct answer to this question is False. 

Myth 9: "Second sight" in the vision of the elderly may be a sign of cataracts. 
[_] True [_] False

It is not surprising that older individuals may think their eyesight is getting better when they become able to read the newspaper without glasses. The truth is they are becoming more nearsighted, which can be a sign of early cataract development. A cataract is not a film over the eye, but is a gradual clouding of the normal lens inside the eye. 
It was once believed that a cataract had to be "ripe" before it could be removed. Today, a cataract may be removed when it handicaps vision significantly at any age. Correct answer is True. 

Myth 10: Cataracts can be removed with a laser. 
[_] True [_] False

This is fast becoming an ocular myth. Cataracts are not removed by lasers. The cloudy lens must be removed surgically. 
After cataract surgery, a membrane within the eye may become cloudy. A laser can be used to make an opening in this membrane. This application of the laser is not to be confused with the surgical removal of the cataract or clouded lens of the eye. Correct answer is False. 

Myth 11: Wearing contact lenses will prevent nearsightedness from getting worse. 
[_] True [_] False

Some people believe that wearing contact lenses will permanently correct nearsightedness so that eventually neither contact lenses nor glasses will be needed. There is no evidence that wearing contact lenses will produce a permanent improvement in vision. Similarly, there is no evidence that wearing contact lenses will prevent nearsightedness from increasing. Correct answer is False. 

Myth 12: Eyes cannot be transplanted. 
[_] True [_] False

The transplantation of whole eyes is currently a scientific impossibility. The delicate optic nerve cannot be "reconnected" once it has been severed. Because of this, the eye is never removed from its socket during surgery. The cornea has been successfully transplanted for many years. This corneal transplant is sometimes confused with an eye transplant. Correct answer is True. 

Myth 13: Working with electric arc welding equipment can weld contact lenses to the eye. 
[_] True [_] False

Exposure to electric arc welding poses no increased risk to contact lens wearers. Obviously, these individuals should take the usual precautions such as wearing protective goggles. No instances of contact lenses fusing to the cornea have been substantiated and there is no scientific evidence that UV light produced by arc welding can cause such fusing. The correct answer is False.
