Iris is software for eye protection, health and productivity. Protect your eyes from the negative impact the PC screen! The 2 most popular features of Iris which probably brought you here are: You can decrease the amount of blue light emitted from the screen and control the brightness without PWM flicker.
There are several different modes and several different types of Iris. These are basically some preset values that many people use. Aside from this you can customize Iris a lot. By default Iris works automatically and detects if it’s day or night. Based on that it will change your screen Color Temperature and Brightness. When you open the control panel of the program you can select different modes and types of Iris.
Some of the benefits of Iris over competitors are that Iris works even on docking stations and monitors connected with USB with the help of my custom High level Color-API. It has a much larger blue light reduction color range compared to all other alternatives, brightness without pulse-width modulation, manual settings, color effects, font rendering, magnification and partial screen blue light reduction with the help of full screen overlays.
Note: In demo version advanced settings are unavailable. If for some reason you don’t like Iris you can check f.lux.
