Whether it is the latest iPhone, tablet, HDTV or some other hi-tech device, we are spending more time using our electronic devices – but is there a price?  

One of the major concerns with digital devices is the blue light that comes from the screen.  Eye care experts are now saying that the blue light emitted by the screens can have serious consequences on our health.  

Parents want to know if these devices are harming their children’s eyes.  The answer is: it may be damaging more than their eyes. According to an article in The Harvard Health Letter (a publication from Harvard Medical School), the presence of light at night “throws the body's biological clock—the circadian rhythm—out of whack,” and in turn, “sleep suffers.” 

For parents, we recommend limiting your child’s usage to no more than two hours a day and to stop using these devices at least two hours before bedtime.  Screen media exposure is discouraged for children less than 2 years of age.   

For those who spend more than 2 hours per day at the computer, etc., and can’t reduce the amount of time spent on digital devices, we recommend wearing special lenses designed to reduce the harmful effects of blue light.
