Children should wear sunglasses to protect thier eyes

For many adults, summer means using cheap Oakley sunglasses. And many parents, worried about the effects of ultraviolet radiation on the eyes, are trying to protect the eyes of their children, too. As a result, the market for sunglasses has exploded.Ophthalmologists childhood that if it is a good idea for babies and toddlers who wear sunglasses in some cases, parents should not be too influenced by the ads for them -or too worried about some "manufacturers suggestions that the sight of a damaged child for not wearing sunglasses.

 Opticians, too, are willing to make a fashion perspective, considering it is so easy to find a good pair of sunglasses for children for $ 10, for $ 100.Children should wear sunglasses "in the prolonged sunlight and intense, pool, sledding and skiing, "said Dr. Gerhard Cibis, chief of ophthalmology at Children's Mercy Hospital Kansas City, Mo." Every time I had put a sunscreen in a child, put his sunglasses. "


 He explained that babies and children lack pigment in the eye lens, which helps to filter ultraviolet rays. Therefore, more ultraviolet rays reach the retina of an infant reaches the retina of an adult. "Cataracts and retinal degeneration in persons aged 70 is believed to be exacerbated by a life of cumulative exposure to ultraviolet light," said Cibis.


 But doctors warn that some sunglasses manufacturers are taking advantage of the lack of conclusive studies. "Many manufacturers use scare tactics to parents that if they put their babies and toddlers in sunglasses, your child will not be able to view in adulthood," said Dr. Robert Gross, a pediatric ophthalmologist at Cook-Ft. Children's Medical Center Worth in Texas.


 "There is insufficent data to justify mandating that all infants and young children should wear sunglasses at all times," said Gross. "However, it certainly would not hurt a child to use when in the sun for long periods of time." Babies under 6 months are usually protected adequately by the hats, umbrellas and awnings stroller. A hat alone can reduce the amount of UV exposure of a child in a stroller by 30 percent.


 "The baby in the car do not really need," said Dr. Charles Merker, a Manhattan ophthalmologist who specializes in children. "They close their eyes." When buying sunglasses, look for a label indicating that it contains polycarbonate lenses approved by the American National Standards Institute, an organization of the test, because they meet industry standards for impact resistance. The label must also say what percentage of UV lenses block: if it is below 95 percent, which pass you by.


 Do not assume that the darker the lens, the better the protection. Tint reduces glare (infrared), but not ultraviolet radiation. In fact, dark lenses without polycarbonate coating can be more dangerous than no sunglasses at all. In bright light, the pupils contract. A dark lens fools the pupil into the expansion, allowing ultraviolet rays reach the retina.


 When shopping, make sure the lens is not deformed. Frames should be rounded and DF3s35FF of flexible material, in the case of some kids who like sunglasses fall.Can use them too? Experts warn parents to remember that for the vision of a child to develop properly, the images must be clear and well defined. By reducing glare, sunglasses also reduce the contrast. Excessive wear, which may inhibit the natural development.
