How long before bed should I wear my blue light blockers?

Many members choose to put on their Blue Light Blockers approximately 2–3 hours before their planned bedtime. This timing aligns with the beginning of the body’s natural “biological evening,” when the brain typically starts increasing melatonin production to prepare for sleep.

If 2–3 hours feels too long initially, you can begin with 60–90 minutes before bed and gradually extend the duration. During this evening window, exposure to blue light from screens and bright indoor lighting can significantly suppress melatonin, potentially delaying sleep onset.
