I hope I'm not missing your point, but here's my understanding of the

As far as I know, relative font sizes are calculated by the browser
relative to a 'base' size. If someone has poor eyesight, they will have
hopefully increased the base size in their browser.

For example, the default base font size in Firefox seems to be 16pt.
'0.8em' should be 80% of this size, so in my browser I should see 0.8em
text as 16 x 0.8 = 12.8pt.

However, if I had increased the base size to 24pt, 0.8em text would be
displayed as 24 x 0.8 = 19.2pt, much bigger.
