AR Glasses to help vision impaired watch TV?

Why I'm asking for input and advice on AR glasses.

My wife has Myopic Degeneration in both eyes and has very reduced or impaired vision. She has not driven in over 5 years and eye glasses or contacts do not correct the vision enough to help.

Currently she reads books etc. on a tablet with the brightness set at max, font size very large and bolded.

For watch television we have an 85" screen size set at dynamic picture settings and even with that she sits about 5 foot in front of the TV while watching.

Anyone have any experience with AR glasses for connecting to and viewing a television? The majority of info of what I have found online is focused mainly on connecting to a phone, laptop, X-box, etc.

TIA and hopefully I get the info I need on the subject.
