Review on Danillsson Unisex Lightweight Blocking Glasses by Ken Reiff

These are very good glasses with all the extras: case, soft pouch, cleaning cloth, even a small flashlight and a card to show the blue color. - Possibility of blocking. And the best part is that the glasses are comfortable and the lenses are nice and clear. There is not much more and the price is reasonable. If you're concerned about the effects of monitor and display light on your eyes, this is a great solution.
