If the glare bothers you that much, cant you buy a pair of "polarised" sunglasses
to play in........and take them wherever your "pinball adventures" may lead?

thats "antiglare" everywhere........

anglers, shooters & drivers have their special glasses, so why not pinheads???

seems a very simple, cost effective purchase that goes where you do and keeps
your gameplay environment consistent

DR

Polaroid film allows transmission of "incident light from the subject" though to your eye
and cuts out "glare" which has not originated at the source.

Thats why it reduces the sun glare off water and may well have a similar effect cutting out
the BG / DMD / overhead lighting "glare" reflected off the PF glass giving you a better
"cleaner" view of the PF and more vibrant true color definition

Has anyone tried playing in "polaroid" glasses? or similarly had a piece of PG glass anti glare
film tinted by a Car Tint company?

I also think the glass composition has something to do with the color appearance as "lead free"
glass is "clear" as opposed to normal glass with a slight "green" look
