What is the resolution limit of the human eye at a standard reading distance?
Show answer and explanation
Correct answer: 0.2 mm
The human eye can distinguish two points as separate if they are at least 0.2 mm (200 $\mu$m) apart. Microscopes are used to resolve structures that fall below this biological limit.
