At Night: The use of blue light blocking glasses is supported during the evening and nighttime hours.

In summary, the appropriate use of blue blockers aligns with the time of day: avoid using them during daylight hours to benefit from natural blue light exposure and consider using them in the evening to prevent disruption to sleep patterns. Always keep in mind the distinction between blue light for healthy circadian rhythms and UV protection for safeguarding eye health.
