This flip-up appears to be quality made and does an excellent job of eliminating glare and "blue" light. All colors seem to be true except for the blue, which is expected. Light to medium blue takes on an aqua tinge and really dark blues turn medium or light blue. I got it to use about an hour before bedtime to eliminate the blue from my TV or any other lights so as to "tell" my brain it is night time and to start producing melatonin! I can actually tell the difference as I usually start yawning and get somewhat drowsy about a half hour after putting them on.

As expected, it has a VERY LIGHT, and pleasing, overall yellow tint to what you are looking at. I'm using it more and more to view my 32 inch 1028 LG LCD screen, and not just before bedtime.
