The New Font In the Upgrade

The New Font In the Upgrade

Hi Team,
Thank you for the update, the new system looks lovely.  However, I find the new font quite difficult to read.  It's not always possible to easily distinguish between an o and an a - and it's not as clear as the old font.  Because the new font is bigger, I also see less information on a screen than I used to.  Is this perhaps something I can fix through viewing options, or is it the way it is?  The font isn't as black, it comes through as a bit "sketchy" on the screen, for lack of a better way of putting it.   Any feedback would be great.
As always, have a wonderful day.
