We’ve seen significant research conducted that blue light (high energy visual light, short wavelength light) before sleep will lower melatonin levels and disrupt sleep. It was then always a logical jump that wearing blue-blocking computer glasses would help you to sleep better at night even after screen use by combatting this problem. Fortunately, this no longer needs to be only an inference drawn by common sense, as a study from the University of Houston has proven that the use of blue blockers will definitively improve sleep quality.
Study participants were asked to wear blue light filtering glasses for three hours before bed and to perform their nighttime routines as they normally would. The study showed that on average, their melatonin levels were increased by 58%-- more than by most over the counter melatonin supplements!
Dr. Lisa Ostrin from the University of Houston College of Optometry, who led the study, was quoted saying that “the most important takeaway is that blue light at night time really does decrease sleep quality. Sleep is very important for the regeneration of many functions in our body…”
Most of the respondents reported that their sleep quality was improved. The study also showed an average increase of 24 minutes per night of sleep.
