How long do I wear blue light glasses before bed?

Updated: Feb 9, 2022

As the sun sets, you begin winding down from a busy day... one filled with stress, and a ton of artificial light. You hope that tonight will be different - that maybe tonight you will get a good sleep and wake up energized for the following day.

You think of all the nights you haven’t slept well, and wonder, "Is actually possible to get a better night's sleep?"... but to heck with it, why not throw on some Netflix and relax. Maybe that will help your body wind down from the day.

As you watch your favourite show, you begin to feel tired, but not quite ready to fall asleep, and all of a sudden its midnight and you realize you have been watching long past your bed time. What has happened? How could you feel tired but not fall asleep?

Blue light exposure late at night is something all of us are familiar with, but are rarely aware of. The same blue light that is coming from your screen time and allowing you the joy of your favourite show is also stopping your pineal gland from producing melatonin - a hormone essential for falling asleep and waking up feeling refreshed the following day.


We live in an age where we cannot escape blue light, it is everywhere. From our phones and TV screens, lamps, overhead lights, street lights and beyond. So how do you balance living in the modern age with a good night's sleep? The answer is simpler than you think.

Blue light blocking glasses are the best and most efficient way to enjoy all the perks of blue light while still allowing your body to get a good night’s sleep. Blue light blocking glasses can block up to 99% of blue lights coming from any source you have on around you, and are an easy way to enhance your sleep. So, when should you put your blue light blockers on?

The best time to put on your deep sleep blue light blocking glasses is approximately 3 hours before your scheduled bed time. Doing this will allow you to continue using your favourite tech while also allowing your pineal gland to produce melatonin for a deep restful sleep. It is important to remember that as soon as you take off your glasses and expose your eyes to blue (artificial) light at night, you stop secreting melatonin - so keep those glasses on.

You can also turn off any overhead lights or any other blue (artificial) light that is not necessary. Reducing the amount of blue light around you (especially overhead lights) while wearing your blue light blockers will help signal to your body that it is almost time to sleep, allowing it to produce melatonin and regulate your wake/sleep cycle.

To summarize:

  • Blue (artificial) light stops the pineal gland from producing melatonin.

  • Melatonin is a hormone essential for deep, restorative sleep.

  • Deep Sleep blue light blocking glasses can block up to 99% of blue light - allowing your pineal gland to produce melatonin even when you expose yourself to artificial light.

  • Put on your DeepSleep blue light blocking glasses 3+ hours before bed, and leave them on until you hit the sack.

  • Turn off any overhead lights that you are not using to reduce the amount of blue light around you as much as possible.
