Yeah, most people use their screens with brightness cranked up and then wonder why they have all sort of problems.
The trick is to set a low brightness, in my case it's a little below what you would call comfortable, but that's because you adapt to it in a sec and will be perceived as good.
If you can't set it too low on the monitor, set brightness to 0 and lower the contrast. If it's still too bright use also brightness/contrast controls in your GPU settings. It is also needed to adjust the settings during the day. But having a more controlled light in your room is a better option.
Once you start getting comments from others that they can't see shit on your screen then you've set the correct level :)
Another very often forgotten thing is to set up correct gamma correction! Yes that thing from CRTs is often needed on LCDs too! LCDs can produce quite big contrast which is unpleasant, for example I set mine to 1.3, fixed it nicely for me.
One approach to find a good value is to have antialiased text both in white-on-black and black-on-white and switching between these. Once the apparent thickness is the same then you've got the right value. Beware of ClearType settings though, you may need to do the test with a classic antialiasing instead.
The result is that you can comfortably use light mode in total dark room without any issues.
Yeah monitor controls can be a problem. You can download an utility to set it from the computer, it's much more comfortable. I'm using one from my monitor vendor, but there are also generic ones.
Search for utilities that can set the monitor using DDC (Display Data Channel).
