Cyxus blue light blocking computer glasses review.
These glasses are pointless unless you are in the sun looking for uv light protection.
I couldn t wear them for long periods of time because they hurt my head because they were so tight and the arms didn t even make it behind my ears.
I love my blu blockers glasses.
They work as advertised and were very helpful with blocking blue light and reducing headaches but these glasses are incredibly small.
8084t01 black verified purchase after a month of heavy use i ve concluded these glasses are well worth it for any person who spends countless hours behind a computer.

These work because the light source has uv light.
Screens don t have uv light that is why when you hold the test strip to the screen that you look at nothing happens.
After shinning the blue light through the lens and seeing that it did not darken the card my husband and i looked around the house for other glassed that were supposed to do the same.
When they arrived the company included a little blue light with a blue light sensitive credit card sized tester.
They provide a blue colored light and a test strip to test the glasses with.
