The Claim

In healthy adults, wearing blue light blocking glasses from 6 PM until bedtime for one week is associated with a small reduction in self-reported sleep onset latency (from 24 to 21 minutes) and fewer self-reported awakenings during the night (from 2.2 to 1.6), suggesting a modest improvement in subjective sleep continuity.

Wearing blue light blocking glasses every evening for a week might help healthy adults fall asleep a little faster and wake up less during the night.
