In snowy Alaska, if you spend hours in the brilliant sun of spring or summer, you risk snow blindness, a sunburn on your cornea from reflected ultraviolet light. For thousands of years (like 2.000 years ago), indigenous peoples throughout that region have had a technology solution: snow goggles, fashioned from a strip of bone, wood or other material, with a slit cut into it, greatly reduced glare and protected eyes from injury. This style of eyewear can even improve vision: the slit focuses the light, much as a pinhole camera does. As a result, far-off objects appear sharper and your vision is much, much better. 1.
