I can see on Youtube that woman with small glasses wore the Sony CC glasses have minor inconvenience but I can see the distance between glasses and CC glasses and it is still adjustable so you can view CC in your comfort where you want move it so you can see entire movie screen or just bottom of screen.
I would support that alot better than Rear Wall Captioning !!! I really hate it at the first day cuz gooseneck don't stay where I wanted, 2ndly, People behind me blocking the rear wall screen when they had to excuse from seat to get something or go to bathroom.
My friend recently went to movie and the theater have new kind of Subtitle device that look so much like Rear Wall Captioning glass with gooseneck except it's electronic and no need to adjust to reflect to Rear Wall. He said it's lot better than RWC BUT the gooseneck is a hassle to keep it steady cuz it sits on cupholder of the theater seats.
So the Sony's Subtitle glasses would benefit the most that you can enjoy watching movie without all those gooseneck hassle. If you happen to bend down to get shared drinks, popcorn or candies near you, you won't miss anything cuz Subtitle still be running within your view!!! It's a minor inconvenience regarding to those who wear Rx glasses. Perhap in near future, they might have Virtual Reality glasses that Sony already have for Gamers may allow you to watch Movie without Rx glasses and have subtitle in it ( I know it may have adjustable lens that you can focus without glasses just like binoculars.) and maybe you can still watch subtitled movie while you go get more popcorns or go to bathroom
Biggest advantage are that if new movie come out on first day, you should be able to be the first to jump in seat and watch movie with subtitle glasses which in past that Every deafie had to wait few months or so to have Open Caption to put on movie that was newly released few months ago. So that's the blessing we get!
So what's the benefit of that and we Deafie are living in world of limitation. It's isn't much limitation when technology improved! I know everyone whines about it because of their opinions of Captioning devices provided by Movie Theater. I admitted I whine big time over RWC!!! and wanted it to be banned from every Theater!! That's my worst nemesis.
