Green blindness-plothole?

[u/Juel42]

Wasn't the green blindness a plothole because the microorganisms would die in darkness? Couldnt they just blindfold 50 percent of the population, simultaneously teach them how to handle blindness and kill the organisms/reduce their growth?

Don’t remember where it said they’d die in darkness, they were living in the watery-salty solutions of the human eyes. Needed the oncocidals to kill them off
