Where can I find a 17" desktop anti-glare filter for my iMac?

Question

I checked a couple of sites that sell anti-glare filters. I'm trying to find one to fit my widescreen 17" iMac, however, both sites charged exorbitant prices, one $80, another $100. I remember ten years ago I was able to buy an anti-glare filter for my old Windows PC, but for some reason, neither the Apple Store, nor Best Buy sell them today. I need one because for the second time in two years, I had to get new glasses as the glare from my iMac is hurting my eyesight.

As I said, I don't think the result from putting a filter over the glass will be satisfactory, regardless of cost.
You may want to find an external matte screen digital (DVI) LCD that you find comfortable to look at, and connect it to your iMac as a second display. Then set System Preferences Displays pane so that it is your primary display (with the menu bar and dock on it). Put that display in front of you, with the iMac off the right as the secondary display. You can still use it (as you desktop extension); hopefully the "glare" will be less of a problem if you are not staring at it constantly. You can go up to 1920x1200 resolution for an external digital display, which is a typical 23 or 24-inch (measured diagonally) widescreen LCD display. I use my iMac that way, with an external display (that I really like) as my primary display and the iMac to the right as the secondary display. Note: It's to the right because putting it to the left blocks the optical drive.
Alternately, if the iMac is in good shape, you can sell it and put the proceeds toward a new Mac mini, and get a display that is comfortable for you.
