I have a desktop application which is basically a reader for different Hebrew texts. I know that in general some fonts are harder to read on a screen than others (both in English and Hebrew).
What Hebrew fonts (or font styles) are best for readability, so a user can read these texts easily for a long time?
Block sans-serif
clear and easy for your brain to parse. It is described here, en.wikipedia.org/wiki/Hebrew_alphabet, in the section Stylistic variants. Note: I can't read Hebrew, I'm just busy first learning the alphabet, and that font style seems ideal for my purposes. It is very neat and clear. – ProfK Nov 7 '17 at 3:09
