HOT ! EMR-TEK Freya Blue Light Blocking Glasses

Blue light blocking glasses with 100% blocking at 400-450nm. Lightweight durable frames with daytime and nighttime lens options.

Blue light exposure during the day causes eye strain and fatigue. Blue light exposure in the evening suppresses melatonin and disrupts sleep. Most people try to solve one of those problems, not both.

The Freya provides 100% blocking at 400-450nm with lens options for both daytime productivity and nighttime sleep support in a lightweight frame built for all-day comfort.

Available with daytime and nighttime lens options. Prescription lenses can be added for combined vision correction and blue light protection.
