Theoretical Investigation of Colored Lenses for Snow Goggles

摘要: Safe driving or skiing in the “arctic whiteout” depends frequently upon early detection of crevasses, fissures, ditches, other sudden changes elevation snow field. It has been believed that there might exist a certain colored glass for goggles which would provide better perception dangerous spots snow. However, no definite answer was available as to what color lenses ought be.The purpose this paper is investigate problem from theoretical point view. found compared with an essentially neutral none glasses ordinarily used improves ability eye detect Even red extreme purity—which according present theory be expected give maximum improvement, are not significantly more effective than glasses.
