Nige greatly prefers paper to screens:
I can testify that my eyes 'went' at exactly the time I began on-screen working in earnest. Now, some 20 years later, when I reach the end of a week crouched over the computer screen, my eyes can barely focus, I am fighting off headaches and feeling a very specific kind of exhaustion which is quite distinguishable from other forms of tiredness. It may be that screens are doing us more harm than we know...
For some reason, I've never had any problem reading screens and no carpal tunnel stuff from constant blogging and barely any back problems.
