Eye doctors have witnessed a surge of eyestrain-related visits in the past couple of decades; they’ve coined the new condition “Computer Vision Syndrome” (CVS). That’s when your eyes spend too much interrupted time staring into laptops, tablets, smartphones, or whatever digital contraption will be added to the market tomorrow.
