You might consider using a video magnifier. There are some that have adjustable cameras for distance viewing, such as
$1. The cost will be higher than other solutions, as much as $2,000-$3,000 dollars, but the level of magnification is high. I use video magnifiers for work and at home, for a wide range of activities, from reading paper documents, to reading whiteboards, to dissembling mechanical keyboard switches. They are fantastic tools. If you decide to go this route, I recommend working with your doctor to try several models that could potentially meet your needs. There are so many on the market, and each one provides specific features and functionality, sometimes for a general audience, and sometimes for specific market segments.
