Pros: Handy utility which makes up for the Apple brightness controls deficiencies.Saves eye strain.Simple keyboard shortcuts.Ĭons: Refuses to start at login.Not needed on MacBook or MacBook Pro.No quick facility to check for updates. Having said that, it's a fairly trivial matter to start the application manually, and the simple keyboard shortcuts allow for easy adjustment of display brightness.For the record, our iMacs are always run with the Apple controls set at minimum brightness, and ScreenShade is then used to further dim the displays down to the required levels.Thanks for providing the software. We no longer have to use eye drops, to alleviate the soreness which is brought on by less than an hour's use of our Macs.On the other hand, our MacBooks can be dimmed to zero with the Apple controls, and so we don't need to use ScreenShade on those boxes.Only one small bug ScreenShade refuses to start at login, despite setting both Preferences and the 'Open at Login' option on the Dock. ScreenShade, whilst not saving any energy - it doesn't actually reduce backlight brightness rather it reduces the display drive signal - is a real eye-saver. Our iMacs default to full brightness at all times, and the built-in screen dimming is nowhere near sufficient to avoid sore eyes in a domestic environment. It's a mystery why Apple insists on us having eye-searingly bright displays by default, in these days of being supposedly eco-f riendly.

I have sensitive eyes as well and do a lot of work at night so looked into getting a screen protector like the kind used on the old CRTS, but they were too bulky, somewhat costly, and did not work well on my 17.3" laptop. This will also block some UV and blue light if you don't want to use software or use some strange Linux on which no software works at all :) Technically you can also lower the brightness by wearing sunglasses in front of the PC. Most LED monitors change the brightness via a process called Pulse-width modulation which is really bad for the eyes. One thing to note is that I don't recommend changing the brightness via monitor buttons if the monitor is LED. To keep iPhone from dimming frequently, you can try to set a later Auto. Iris can do this also but this is not related to the question. If you set a sooner Auto-Lock, your screen will dim frequently. One plus of Iris over f.lux is that you automate the brightness reduction based on day and night just like most blue light filter programs do with the color temperature and blue light. Iris and f.lux should work fine because they change the white point of the screen which is better. This method reduces contrast quite a bit and may cause eye problems.
