Over-the-counter Color Contact Lenses May Contain Chemicals Harmful to Eyes
If you’re thinking of getting decorative contact lenses online, you might want to think twice. In fact, be afraid. Be very afraid. It’s not worth the risk to your vision. The American Academy of Ophthalmology has issued a warning about over-the-counter cosmetic contact lenses after a new study found that several varieties tested positive for chlorine and other harmful chemicals. These lenses can harm the eyes by causing corneal ulcers or keratitis. Both can result in scarring that impairs vision or causes blindness. Researchers from Japan, where decorative contact lenses are very popular, published a paper in September that found chlorine and iron in several types of non-prescription colored contact lenses. Researchers say the chemicals may come from colorants used to tint and create patterns on the lenses. Their study also noted that colorants printed or pressed onto some decorative lenses create an uneven texture that could scratch the front of the eyes, potentially increasing the risk of infections that could cause blindness. Four of the five lenses in the study are not available legally in the United States because they are not approved by the Food and Drug Administration. However, many decorative lenses of unknown origin can be bought online without a prescription.

Study shows that the overnight use of the OrthoK lens was more effective at inhibiting axial eye growth and myopia progression than daytime wear of a conventional rigid gas-permeable (GP) lens.
For this prospective study, the researchers employed a contralateral-eye crossover design. The 26 children in the study were fitted with an OrthoK lens in one eye for overnight wear and a GP lens in the contralateral eye for daytime wear. This protocol was followed for six months. After a two-week washout period, the lens/eye combination was reversed, and the lenses were worn for an additional six months.GP lens–wearing eyes showed progressive axial length growth throughout the study. After the first six months of lens wear, axial length had increased by 0.04 ± 0.06 mm in the GP eyes but did not change in the OK eyes. In the second six-month period, OK eyes again showed no change in axial length, while axial length increased by 0.09 ± 0.08 mm in the GP eyes.
Are 3-D Movies Safe for Kids’ Eyes?
With the popularity of 3-D movies likeBrave, The Avengers and Dr. Seuss’ The Lorax, a lot of people are wondering about 3-D technology and eye safety. Is 3-D technology healthy for your eyes? What about your kids? The American Academy of Ophthalmology says there is no reason to be concerned: 3-D movies, TV or video games will not damage the eyes or visual system. Some people complain of headaches or motion sickness when viewing 3-D, which may indicate that the viewer has a problem with focusing or depth perception. Also, the techniques used to create the 3-D effect can confuse or overload the brain, causing some people discomfort even if they have normal vision. Taking a break from viewing usually relieves the discomfort. Children or adults who have vision disorders like amblyopia or strabismus may be more likely to experience headaches and eye fatigue when viewing 3-D digital images.
What Parents Need to Know about Pink Eye
Each year, conjunctivitis is the cause for many missed school days. In general, conjunctivitis remains contagious as long as the eye tears and produces discharge. Once these symptoms are gone, it’s safe for the child to return to school or child care. Some schools may require a certain wait period before the child can return.Pink eye symptoms usually improve in three to seven days, but some viral infections can last up to 2 weeks. Take your child to an ophthalmologist to ensure they get proper treatment. Good hygiene – especially hand-washing after touching the face or eyes – is crucial to minimize spread of the disease in classrooms and households:Wash your hands frequently and after touching your eyesDo not reuse handkerchiefs or towels when wiping your face and eyesChange pillowcases frequentlyDo not share towels with othersDo not use old cosmetics or share makeupFor more information about pink eye and other children’s eye health information, visit www.americaneyecentervn.com ******************** Ask Dr Nam Tran: Question:My seven year-old son was prescribed glasses a year ago after "failing" his checkup. This came as quite a surprise as he is an advanced reader, does very well at school and plays sports without issue. After a year he still insists that the glasses don't help. He will wear them because he is a good boy. He says they make things bigger, but that it doesn't make it any easier. He is a bright boy, and I believe he is telling the truth. Should we insist he wears them? Answer:Rather than insist that your child wear glasses that he feels do not help him, I suggest that you seek a second opinion. You child has probably been given a prescription for hyperopic (farsighted) glasses. Most children with mild hyperopia see well without glasses and therefore do not need glasses. There may be other reasons why your child may need glasses, such as to keep the eyes straight or to prevent headaches. A second opinion can help you to make an appropriate decision regarding glasses.
