How do you reduce monitor glare on an LCD screen?

I just purchased a 22" Acer LCD monitor and I just figured how to let the monitor auto-adjust itself to my liking. However, there is still a "glare" to it that makes images more fuzzy. It really doesn't bother me, but it could be sharper- and it's a tad too bright. Would buying a privacy/anti-glare filter for my monitor help?
There is no source of light nearby, the glare is coming from the monitor itself!
