TrueDark Sleep Hacking glasses are like noise-cancelling headphones for your eyes!

Not all light is created equal and the wrong lighting at the wrong time of day can ruin your sleep, performance and health.

Your eyes have special cells filled with a very light-sensitive protein called melanopsin. These cells signal to your brain that it's daytime when they are exposed to certain wavelengths of light. This causes your brain to stop producing hormones, such as melatonin, that are essential to having a restful and productive night of sleep.

Traditional blue blockers are good at filtering out blue light, but it's not only blue light that affects your sleep. Spectrums between the colors of yellow and purple can interfere with the melanopsin in your eyes and make it very hard to fall asleep properly. This is why staring at a computer screen or phone before bed can interfere with your sleep!

Patent-pending TrueDark Sleep Hacking glasses are the first and only glasses designed specifically with multi-layer optical filters that block ALL of the sleep and performance robbing wavelengths in the evening hours. #StopJunkLight with Sleep Hacking technology that frees your hormones and neurotransmitters to do their best work.

TrueDark Sleep Hacking glasses allow you to see, read, watch TV and do other household activities while simultaneously tricking your brain into thinking it's completely dark. This causes your brain to start getting ready for bed, which can help you fall asleep faster and have a more rejuvenating and productive night's rest. They are great for treating jet lag, too!
