No more eye strain, tired eyes or  headaches from the long hours I spend looking at my computer and phone screen with these CADDIS readers, thanks to the  frequency lenses technology that blocks 45% of harmful blue light, And the anti-reflective coating helps to minimize glare and reflections. These are the best damn readers I've ever owned! Try them for yourself! http://liketk.it/3lJqv @liketoknow.it #NikkiFreeStyle #liketkit #LTKcurves
