I love my blu blockers glasses.
They provide a blue colored light and a test strip to test the glasses with.
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.
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.
These glasses are pointless unless you are in the sun looking for uv light protection.
These block at best uv light.
