This will give you an idea of how well your blue blocking glasses are performing.
Turn up your screen brightness all the way and compare the two bars below.

Blue Blocker Test Strip

With your blue blockers on, the two strips above should look identical.

Note that only laboratory testing can really tell you how your glasses are performing but this can give you a pretty good idea. Also not all screens and color settings are the same. Try this test out on different screens and see if your results are consistent.

If your current blue blockers are not up to par, give ours a shot!
