Roboto typeface has been upgraded thanks to Google and Material Design Guidelines. The new font is specific for screens, which makes sense given the digital age that people live in these days.
"Changes to the font include tuning to work across more screen sizes and conditions, from watches to desktops, televisions to cars," states DesignBoom. This should allow people to read messages easier, and avoid straining the eyes too much. The font itself is very minimalist with a clean and clear design, and even the smallest of changes to this typeface made a difference. For something like lettering, even just an elongation of a line can give an T a completely different look.
Hopefully these changes will allow people to read items on their digital screens without too much strain on the eyes.
