For visually impaired and blind patrons, most theatres here in the Bay Areea in the California have live audio description. Certain dates would have a live describer sitting in the sound booth or location reading from a script or describing on the fly through a radio transciever, and the patrons would all have little radios and earpieces so they could enjoy the performance and hear the description at the same time. The descriptions would include details of set design, costumes, and actor appearance during the pre-show seating time and during intermission.
Some larger shows like Wicked and Hamilton use an automatic description system called GalaPro, which is a device that has both audio description synced to the lighting cues of the show along with captions. There is also a mobile app for the same thing, but I've had terrible experiences with both and do not recommend them at all.
Using a live audio description service is much preferred.

Look into audio description and touch tours. Theater has been accessible for blind people for the last 35 years, so there is already a lot of precedent and best practice. If there are audio describers in your country, you should hire them to do this rather than doing it yourself so that the quality is better. If the quality is better, patrons will return.
