Thanks to them we see light and images in full color.<\/p>\n<p>But in 1998 one scientist named Ignacio Provencio found a new photoreceptor called Melanopsin.<\/p>\n<p>Melanopsin evolved millions of years ago to help early human distinguish between day and night and to regulate their circadian rhythms or in short to help our brain tell our body when to sleep.<\/p>\n<p>This was normal when we only had light from candles and campfire, but lately, we are bombarded with all kinds of electronic devices and especially devices containing LED diodes.<\/p>\n<p>This photoreceptor Melanopsin activates when blue light goes into eyes. The idea of nature was that if the sky is blue then it&#8217;s day and it&#8217;s no time to sleep.<\/p>\n<p><a href=\"https:\/\/iristech.co\/wp-content\/uploads\/2017\/12\/Circadian-Rhythm.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5690\" src=\"https:\/\/iristech.co\/wp-content\/uploads\/2017\/12\/Circadian-Rhythm.png\" alt=\"\" width=\"886\" height=\"882\" \/><\/a><\/p>\n<p>However today the same kind of blue light is emitted from our monitors and we just can&#8217;t go to sleep at night, because our Melanopsin photoreceptors are overstimulated and our Melatonin secretion is stopped, because of this.<\/p>\n<h1>How Iris works?<\/h1>\n<p><a href=\"https:\/\/iristech.co\/wp-content\/uploads\/2017\/05\/iris.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4323\" src=\"https:\/\/iristech.co\/wp-content\/uploads\/2017\/05\/iris.png\" alt=\"\" width=\"540\" height=\"547\" \/><\/a><\/p>\n<p>To fix this problem and to help you to fall asleep faster Iris is gradually decreasing blue light at night. This helps your body to produce more melatonin and your melanopsin photoreceptors and not overstimulated.<\/p>\n<p>Reducing blue light is also beneficial during the day since blue light is the light with shortest wavelength and it enters really deep into the eyes.<\/p>\n<p>If you had heard that X-rays are bad for you, then you should know that blue light is the closest visible light to UV light and X-rays.<\/p>\n<p><a href=\"https:\/\/iristech.co\/wp-content\/uploads\/2017\/12\/Visible-spectrum.jpeg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5692\" src=\"https:\/\/iristech.co\/wp-content\/uploads\/2017\/12\/Visible-spectrum.jpeg\" alt=\"\" width=\"2514\" height=\"1200\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<p>Iris reduces the blue light by lowering the light emitted from the blue subpixel of the screen.<\/p>\n<p>The orange, yellow or red color of the screen is just a side effect of this blue light lowering. It will probably take you some time to get used to this, but after a week you will not be able to disable Iris at night without feeling a massive amount of eye pain.<\/p>\n<p>The light emitted from the screen without Iris looks like this<\/p>\n<p><a href=\"https:\/\/iristech.co\/wp-content\/uploads\/2017\/12\/100p.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5693\" src=\"https:\/\/iristech.co\/wp-content\/uploads\/2017\/12\/100p.png\" alt=\"\" width=\"840\" height=\"349\" \/><\/a><\/p>\n<p>And with Iris to the lowest setting, it looks close to this<\/p>\n<p><a href=\"https:\/\/iristech.co\/wp-content\/uploads\/2017\/12\/0p.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5694\" src=\"https:\/\/iristech.co\/wp-content\/uploads\/2017\/12\/0p.png\" alt=\"\" width=\"843\" height=\"345\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p class=\"excerpt\">How modern monitors work?
