Block Blue
Do these sunglasses block out most blue light?
Here is a spectrographic analysis of my glasses: http://www.flickr.com/photos/31355277@N03/4475936313/ along with a photo of the glasses. How can I tell if sunglasses are good at blocking blue light?
The wavelength of visible blue light is around 475. This shorter wavelength means that the light will be scattered more then the other visible light. Your glasses seem to block out blue light, but not most of it. I hope I helped, but was unsure of how to best answer your question. I do not know how other glasses compare, but you can check your chart at the 475 mark to see if other glasses beat them.
