There are quite a lot of fonts available for writing Latin, which have been designed for easy legibility and contain all the letters of the Latin alphabet.

For the Greek alphabet, however, most modern fonts are designed for modern (monotonic) Greek, and thus aren't designed to make (e.g.) ἔ and ἕ easily distinguishable. Most of the time, I need to zoom in quite far to see the distinction between those two, which is annoying while reading or translating.

So, what are some popular fonts designed specifically for polytonic Greek? My eyes would appreciate anything with easier-to-read breathing marks.
