Nintendo 3DS Could Help Find Vision Issues According to Optometrists
U.S. eye specialists are welcoming the Nintendo 3DS game device, dismissing the manufacturer’s warnings that its 3-D screen shouldn’t be used by children 6 or younger because it may harm their immature vision. On the contrary, the optometrists say, it’s a good idea to get your kids to try the 3-D screen, especially if they’re younger than 6. It won’t do any harm, they say, and it could help catch vision disorders that have to be caught early to be fixed. The new handheld game device is already available in Japan and goes on sale in the U.S. on March 27 for $250.
Today’s 3-D viewing systems send different images to the right and left eyes, a technique that creates an illusion of depth. But a lot of the cues we use to perceive depth in our environment are missing. That confuses the eyes and accounts for the eyestrain and headaches many people experience watching 3-D movies. Because of that, optometrists say, these systems can help isolate problems that have to do with the way the eyes move, problems that aren’t caught by eye charts. These problems are much easier to fix if caught before age 6, when the visual system in our brains is more or less done developing. Only 15 percent of preschool children get a comprehensive eye exam that could catch these subtle problems, according to the American Optometric Association, the professional group for optometrists.
