For people with Seasonal Effective Disorder (SAD), studies published at the National Institute of Health (not studies done by product manufacturers) indicate blue light therapy is effective for treating SAD. So if you start employing blue light therapy (30-60 minutes each morning) and at the same time start wearing blue light blocking computer glasses all day, wouldn’t the glasses potentially negate the beneficial effect of the blue light therapy since you are offsetting it by wearing the glasses all day?
Simply put, should people with SAD avoid wearing blue light blocking glasses during the darker months?
