Here's a video where someone tests some clear blue blockers with a spectrometer.

PS - just for completeness. It is possible to block three narrow bands of blue, green and red light equally and obtain a lens without apparent tint, That wouldn't be particularly effective against broad band blue light and I doubt that is what is being offered in this product in any case, but it is a possible solution if narrow band blue blocking is all that is desired.

For $10 for a 2-pack though, seems like a low-risk try. Worst case they're just cheap screen glasses you can leave at your desk/work bag.
