The temporal fluctuation of need something that almost everyone with low
vision experiences. This happens through the day, and over years. Over the
years I have used less and less saturation with my colors. Font size is
another. In the morning I only need 300% as the day goes on font size goes
up. Things like letter-spacing depend on the available font families. I
also used to go down to 250%, but no more. I have a few font families I
like: PT Sans, Open Sans, Tahoma. Since each applications gives you a very
limited choice I pick the closest to one of these three. Comic sans is
actually a very good font for distinguishing letters. Each time I use an
application I pick the closest thing to what really works for me.

If you take another person with visual acuity the same as me who also has
retina scotoma and weirdly you'll find a host of other choices.

Best Wayne
