NightFall Blue Blocking Glasses feature the signature blue AND green light-blocking red lens. These are the most optimal blue light-blocking glasses available for optimising sleep and balancing hormones.

Block Blue Light's optical grade red lenses block 100% of blue and green light from 400nm to 550nm. This is the exact range that has been shown in clinical trials to lower melatonin and negatively impact our sleep.

These scientifically-designed-and-manufactured blue and green light-blocking glasses not only block blue light but make you look good while doing it!

Featuring the custom-designed Noctural Red 550 Lens, these glasses have been specifically designed and proven to block 100% of blue and green light from 400-550nm.  This is the exact range of blue and green light shown in scientific studies and trials to lower melatonin levels and lower sleep quality.

Green light is right next to blue light on the visible colour spectrum, this means that the "melatonin disruption zone" also extends into the green light range. Green light up to 550nm at night can also send daytime signals to the brain. For optimal night-time protection, we need to remove 100% of blue AND green light up to 550nm.

Be careful, as there are many other "blue blocking" glasses on the market that have not been verified to block all the required blue and green light wavelengths which is essential for these glasses to be effective and provide adequate night-time protection!

NightFall glasses use the world's most advanced blue and green light-blocking lenses designed for after-dark use, making them much more effective at reducing the harmful effects of blue and green light and improving your sleep.
