The text claims that being in complete darkness for more than 3 days can cause permanent blindness.

Infact verdict: Mixed (42/100).

The claim that being in complete darkness for more than 3 days can cause permanent blindness is not strongly supported by evidence. While some sources suggest that prolonged darkness might lead to temporary vision issues, there is no consensus or strong evidence indicating that it causes permanent blindness. Most sources indicate that normal vision typically returns once exposed to light again. Therefore, the claim is misleading and lacks substantial support from authoritative sources.
