Have read that blue-light blocking glasses are not necessary, except that wearing them might help if you are on your devices late at night, to reduce insomnia. Eye strain can be reduced by using the 20-minute tactic:. Every 20 minutes, look away from your screen at something at least 20 feet away, for 20 seconds.
It irks me that Q is promoting inaccurate info and preying on fears.
The glasses are cute, though.
