'The last few years have seen a radical shift in how our children use their vision. More and more time is spent looking at an electronic screen; TV, computer, cell phone, game device, and so on. Vision scientists have long pointed out that excessive near-point tasks can lead to increased myopia (nearsightedness) in children, eyestrain, and headaches. Combined with the potentially damaging effect of the blue light these screens emit, and you have the possibility of a dangerous situation. We recommend a common-sense approach. First, limit the time your child has to electronic media. Psychologists, educators, and doctors all agree: too much is not good. Second, practice the 20/20/20 rule. For every twenty minutes of near-point tasks, take twenty seconds and look at something twenty feet or more away. In short, take frequent rest breaks. Third, use lenses that are designed for your particular activity. Having the correct eyeglass or contact lens prescription is always the place to start. There are lenses and coatings that not only provide the proper focus but also block unwanted glare and limit the amount of damaging blue light.
