How can I reduce glare on my computer monitor?

I use a 19 inch LCD monitor and sit with my back to the windows. During some times of the day I get reflection from the sun - however moving my desk isn't an option. I've tried looking on Amazon for anti-glare devices, but none with good reviews fit my screen. What can I do to reduce the glare on my computer?

You can go with a good old standby: A filter.

These are probably the very best, but you can find less-good ones, which are cheaper.

If you can't avoid overhead light, you can construct an anti-glare hood for your monitor by taping together several sheets of black cardboard and using them to frame your monitor screen.
