So far, you have only explained your visual condition, nothing about what is
presented to your eyes.

Therein lie multiple problems. A 23" 1920x1080 screen is indeed 95.8 DPI.
Xorg, unless overridden, same as Windows and Mac, presumes a 96 DPI screen.
By default, all popular Linux DEs obey the Xorg configured DPI. In all such
environments, the 13px CSS "size" used for the items in the footer columns
does in fact compute to a physical size of 9.75pt.

Problem 1: For today's Internet, where yesteryear's CRTs are mostly memories,
and laptops and smaller internet access devices abound, selling in far larger
numbers than "desktop" computers, 96DPI is a low density screen. Low density
means objects of any given nominal "size" are rendered large in comparison to
screens of medium or high density. What is adequate in size on a low density
screen morphs into inadequacy as actual screen density increases. Without the
user environment applying any compensation, that 13px/9.75pt text on a 96DPI
screen becomes 13px/7.8pt on a 120DPI screen, 13px/6.5pt on a 144DPI screen,
13px/5.2pt on a 180DPI screen, and so forth. So clearly from a usability
perspective, since it exhibits zero adaptation to the user environment, the
px unit makes a poor choice for sizing web objects that need to be legible.

Problem 2: Just because everybody else does something does not justify
everyone else doing the same. Copying what everybody else does only makes
more of the same, not wisdom. Computers are tools with the capability to do
things automatically, to make things easier. Sizing web content in CSS px
units impedes a computer's ability to do that. Better sizing options exist
and are therefore recommended.[1]

Problem 3: Sizing using px units completely disregards user needs and
preferences. Users' browser defaults are presumptively optimal. Users who
find the as shipped defaults inappropriate are free to adjust them. One word
describing that process is called personalizing. Disregarding what users find
optimal is rude, and for the same reason as problem 2 above, just as unnecessary.

>- you should really ask yourself to consult a doctor and check your eyes

WRT viewing a computer display, there is nothing wrong with my eyes that
prescription lenses don't correct. The problem is with web designs that
override user settings, either by disregarding them entirely (sizing in px),
or assuming them inappropriate (base sizing to other than browser default,
e.g. body {font-size: 80%} or p {font-size: .8rem}). 100% is the
presumptively optimal base size for everyone. It's personalizable precisely
so those who don't like the size it was shipped with can optimize it, thus
allowing the computer to automatically compute, making everything nice size

> and that is by far meant insulting (see above paragraph!)

You have me totally lost by that comment.
