The sta­tis­tics are re­veal­ing. About 30 per­cent of adults now spend more than half of their wak­ing hours on a dig­i­tal de­vice. And 83 per­cent of chil­dren be­tween ages 10 and 17 use dig­i­tal de­vices for more than 3 hours a day. An es­ti­mated 73 per­cent of 9- and 10-yearolds, and 80 per­cent of 13- and 14-yearolds now suf­fer from tech­nol­ogy-in­duced sleep dis­or­ders. More chil­dren than ever are becoming near­sighted. The most alarm­ing statis­tic is that 70 per­cent of Amer­i­cans cur­rently ex­pe­ri­ence some form of dig­i­tal eye strain, ac­cord­ing to the Vi­sion Coun­cil.

Peo­ple aren’t go­ing to stop look­ing at com­put­ers, so the so­lu­tion is to make th­ese de­vices eas­ier on your eyes. “Eye doc­tors have long rec­om­mended tak­ing fre­quent breaks, ad­just­ing work sta­tions to be er­gonom­i­cally cor­rect, and us­ing proper eye­wear. Many ded­i­cated videogame play­ers have long praised com­puter eye­wear such as Gun­nar Op­tiks’ which is backed by two clin­i­cal tri­als. Now the rest of us are dis­cov­er­ing the im­por­tance of wear­ing high-tech eye­wear de­vel­oped specif­i­cally for com­puter and other dig­i­tal de­vice users. How much of the blue light spec­trum do the lenses fil­ter? “The lenses should fil­ter the spec­trum be­low 450 nanome­ters of blue light. If they don’t fil­ter the right blue light fre­quency, they won’t pre­vent dig­i­tal eye strain. Also, some lenses fil­ter only about 10 per­cent of the blue light. Oth­ers fil­ter as much as 65 per­cent. The best as­sur­ance that you’re get­ting the right type of blue light fil­ter is to choose eye­wear made with a com­puter-spe­cific color for­mu­la­tion that is in­te­grated di­rectly into the lens ma­te­rial, and not ap­plied as a sur­face treat­ment. Th­ese are con­sid­ered med­i­cal de­vices.”

Is there an anti-re­flec­tive (AR) coat­ing? “Peo­ple don’t re­al­ize that when you look at a com­puter, your blink rate re­duces to about one third. Your eyes get dry. Com­puter eye­wear with a wrap­around de­sign that fits close to the face min­i­mizes dry eyes by hold­ing more hu­mid­ity be­tween the lens and your eyes. This is of­ten one of the first ben­e­fits peo­ple no­tice.”
