    Many researchers believe that the reason why so many people are nearsighted (meaning they can't see far away) is because we don't need distance vision anymore.

    Several generations ago, nearsightedness was nearly unheard of among Alaskans, because they were continually looking out to the horizon for information about the weather. Two generations later, and with the incarnation of TV and computers, 30 percent of Inuit kids are nearsighted. Similarly, the Nepalese people believe that those with problems seeing distance should stare at the moon to help exercise and train their eyes to see far away.
