I can work with the rest of the lights in the room turned off and I have plenty of light, and NO glare. It swivels and and can be adjusted to direct the reflected light wherever I need it.
All these years staring at a monitor and I would have never thought to buy this thing. ;)
I simply have a strongish lamp shining on the white ceiling, without the normal room light on, which gives a soft glow to the whole room. Same idea.
I've been using a desk light shing onto my desk for years now. I read your post, turned the lamp around, so that it shines onto the wall, and my eyes feel better already after just ten minutes.
I feel so stupid that I didn't think of this myself a long time ago.
Thanks for the tip, Woz.
Do NOT turn off all the other lights in the room while working at the computer.
Your eyes need a balanced luminous environment. Just lighting your screen (from the inside ;)), the keyboard, and the close environment around them while leaving the rest of the room in the dark will cause fatigue and eye strain, because your eyes will continuously have to adapt back and forth between very different light levels.
The physiological optimum described in various standards says that the contrast (luminance, cd/m2) in the "infield area" (your work environment as described above), should not normally exceed 1/3. The contrast between "infield" and "outfield" (the rest of the room), or within the "outfield" should not normally exceed 1/10.
Note that contrast doesn't mean the quotient between two values, it is the quotient beteween the difference of the two values and the smaller value. I can scrape more details and reasoning from the back of my mind (and my documentation) if anyone cares.
This isn't to say that you didn't get a cool light. It's quite adequate for the task, mainly because it decently illuminates your workspace without causing glare on the monitor. Just that doing this isn't enough to cater for all your visual needs.
Another tip: If you set the lighting so that the area behind you is dark, then you'll reduce reflections and potential glare on the monitor even more.
Unfortunately, typical office lighting installations in the US are completely inadequate for any kind of computer work. They tend to radiate equal amounts of diffuse light into all directions. What you need instead is a lighting system that has a relatively low cut-off angle. All the light should leave the fixture in the range between 0 degrees (vertically) and around 50 degrees (slightly above the diagonal). No light should be emitted above that limit, or it will shine on your monitor in an angle that causes a bright haze, reducing the contrast of the display and thus the legibility of its contents.
If you find any way to modify the lighting in your office according to those requirements, then you can safely turn the lights back on. Otherwise, they'll continue to be a health hazard to you and your coworkers.
I tend to sit with my face right up to the screen, successfully reducing my eyes and brain to jelly.
Besides the lighting, you either need a better monitor, some glasses, or both. Ask your employer for an LCD screen. Your increased health, happiness, and productivity will amortize the costs for them probably within a few months, if not weeks.
