Umizato Classic Stainless Steel Round Blue Light Glasses - Flexible Durable Corrosion Resistance, Blue Blockers Glasses, Circle Wire Womens and Mens Blue Light Glasses Metal Frame (SUMI in Rose Gold) I've not found any evidence that blue light is damaging to the eyes. I'm not a doctor. I have read that they may allow you to sleep better. The operative word is may. My only reason for using them is that word "may". These seem to be good quality. The word that jumped out at me when I read the description was oversized. I incorrectly assumed that they would be oversized. They are not. They are considerably smaller than my normal glasses. I wanted a pair of blue light glasses which would fit OVER my own glasses. I thought oversized would do it. I was wrong. If you are not planning on wearing these over your normal glasses these are very nice quality. $49.95 $49.95 99% MORE RELAXED - Wear these blue light glasses...
