Product description
Blue light after dark squashes your natural melatonin production
Block it!
Blue light exposure at night has been proven time and time again to be disastrous to your body’s internal clockwork. Your brain tracks the time of day with special receptors in the eye that sense lighting conditions. They are specially tuned to be sensitive to blue light. This is a problem because blue light exposure after dark sends daytime signals to your brain. This can scramble you natural circadian rhythm. Not Good…
The Disruption Zone
While the body is sensitive to higher levels of all visible light, the range of 450 – 510nm is by FAR the most disruptive. This is longer blue and cyan wavelengths that clear and yellow tint lenses are helpless to block.
Virtual Darkness Safely use computers, tablets, and phones after dark Protect yourself from blue rich LED and florescent lights Allow your body to shift effortlessly into nighttime physiology Enable rapid sleep onset and deep natural sleep cycles Virtual personal darkness can be taken with you anywhere you go!
Fits over your prescription and reading glasses
No need to buy expensive custom made blue blockers. These light-weight glasses fit over top of your prescription and reading glasses instantly transforming them into world-class blue blockers!
They work great by themselves as well!
Do you only wear glasses sometimes?
These work really well as stand alone glasses. Some people use them by themselves and use them with glasses only as needed as needed. You can watch TV without them and then pair them with your reading glasses for using your tablet. This is one major advantage over the clip-on style lenses.
Easily put them on and take them off
They just set over top of your regular glasses. There are no clips to deal with. This is very convenient if you use multiple glasses or if you use them with glasses only some of the time.
Don’t let blue light ruin your sleep!
By now we all know that screens emit a high percentage of blue light which is bad for sleep. Now when you need to use your tablet or other screens before bed, just put these on first. Problem solved!
Instant relief for your eyes
In addition to shielding your melatonin production from blue light, your eyes will thank you as well. Short wave blue is one of the main causes of eye strain and fatigue. Block it!
