The reporter found that children’s sunglasses were sold in some optical stores, stationery stores, jewelry stores and even supermarkets in Lanzhou, with prices ranging from tens to hundreds of yuan. Is it necessary for children to wear sunglasses? Which sunglasses are suitable? The reporter interviewed Wang Haiyan, chief ophthalmologist of the First Affiliated Hospital of Lanzhou University.
Wang Haiyan told reporters that the damage to eyes caused by strong sunlight in summer mainly comes from ultraviolet rays. In particular, harmful light waves in ultraviolet rays damage people’s cornea, lens and retina. If they are exposed to ultraviolet rays for a long time, their eyes are easy to be damaged, causing eye diseases such as keratitis and cataract. Children are no exception, and their eyes are more vulnerable. “Wearing sunglasses to protect eyes is beyond reproach, but parents should buy Sunglasses for children under the guidance of doctors, and choose Sunglasses with quality certification from regular manufacturers. Sunglasses should be marked with anti UV function.”
Wang Haiyan said that when parents buy Sunglasses for children, they should try to choose gray and Tan sunglasses, and avoid choosing Sunglasses with incorrect frames and different lens thicknesses, pink or blue. “Grey and Tan sunglasses can more effectively maintain the color of the object itself and filter harmful ultraviolet substances. Pink or blue sunglasses not only have no function of blocking harmful ultraviolet substances, but sometimes absorb harmful substances and have a negative effect.”
In addition, some children wear sunglasses indoors and outdoors in order to “play cool”. “This is undesirable. You can wear sunglasses outdoors to protect your eyes, but you should take them off indoors because the light is dark indoors. Wearing dark sunglasses will cause long-term eye fatigue, eye muscle tension and blurred vision.” Wang Haiyan said.
Wang Haiyan suggested that children under the age of six do not need to wear sunglasses, but can protect their eyes and sun by wearing sunshades and umbrellas. Some children with squint, amblyopia, hyperopia and other eye diseases should wear sunglasses with caution. Improper selection is more likely to cause damage to eyes. It is also an effective way for children to protect their eyes to avoid looking directly at the sun, to go out between 10 a.m. and 2 p.m. when the ultraviolet rays are strongest, and to stay outdoors for a long time.
