Can flies be blinded by sitting on a lightsource with the many eyes they have?
In: Biology
a fly shat on my food so i pointed a “military grade” laser pointer at it.. i don’t think it liked it but im sure it wasn’t blind afterwards.
It won’t blind them, our lights aren’t bright enough for that.
However! Stobe lights completely break their brains. They just can’t deal with them, and so they go from being flies to being walks. And as long as they’re walks you can walk right up to them and swat or capture them, you don’t even need to move quickly.
Short answer: No, at least not our bulbs.
Insect see different wavelength than us, its more limited, meaning a ultrabright light to you, might only be seen as a normal red light to a fly.
However, if you have a light source that emit only the kind of wavelength that flies can see and turn the output to max, yes you can blind them.
No they cannot become blind because if that was true you would never see insects under broad daylight and they would be all nocturnal.
