Eyeglass Cleaner Ruined My Matte Screen?

Try removing all of the matte finish with the eyeglass cleaner. Go get some matte art fixative at a craft store. Mask off the bezel with tape and respray it.

Looking at the picture my money is on something getting under the top layer-look at the edge pattern between good and damaged.
Did you spray cleaner directly on the screen? If so it may have puddled a little and been siphoned between the layers.

I've seen large, flat panel TV screens lose their anti-glare coating (purple, dichroic coating) by a housekeeper using Windex on it. So it's possible that your laptop had a polymer-based film as an anti-glare coating, that got dissolved by the ammonia or some other ingredient in the eyeglass cleaner. You might be able to apply an anti-glare film over the screen, but you will have to do some research on an appropriate film.
