Master Your Screen's Color Temperature. The easy-to-use Blue Light filter.
Ever wonder why your eyes are dry or fatigued
after a few hours of computer use?
Blue Minus helps to reduce eyestrain while working on your
computer by scheduling changes to your screen's blue light levels.
It does this by adjusting the temperature of the colors displayed on your screen.
Tend to wake up at 3AM to start your day? Make that your "brightest / bluest" time.
Work in a dimly-lit office environment from 9AM to 5PM? Adjust this part of your day to be "warmer."
Blue Minus is free for personal use and for commercial use by organizations with ten (10) or fewer total employees.
Commercial licenses are $5.00 USD per person per year.
