Eye Mastery (Day 1)

The Science behind Iris and Why it works?

When you first start Iris you will see how your screen becomes more orange and also a little bit more dimmed.

You may wonder how this colors will actually help you feel less eye pain and sleep better, but the science behind Iris is actually really simple.

Blue light and Melatonin

Millions of years ago when humans were living in caves and still didn’t had clocks they oriented if it’s day or night by the blue sky.

And looking at blue light controls the secretion of our sleep hormone Melatonin.

Time passed, we evolved and today we spend almost all of our days in front of electronic monitors which emit a lot of blue light.

We will go into more details about this, but for now, just remember that avoiding blue light at night helps you to sleep better at night.

To help you with this Iris will gradually regulate blue light day and night. The orange tint is just a side effect of the decreased blue light and color temperature of the screen.

Brightness and PWM flicker

The second bad thing about our monitors today and especially about LED monitors is that they flicker.

Monitors are like a lightbulb, but instead of 1 lightbulb, you have millions of them in the size of several inches.

In order to not burn them, you need to turn them ON and OFF hundred of times per second.

And this thing, this ON and OFF thing is called flicker.

Our brain is so slow that we don’t perceive it, but our eyes are fast.

Our Iris starts to open and close like a muscle and this is one of the main reasons why we feel eye pain when we sit in front of the computer.
It’s a lot more complicated than this, but for now, just remember that Iris optimizes this screen pulsations by controlling the brightness without PWM and this helps you to feel less eye strain.
