Every human eye perceives the exact same visible light spectrum
the verdict
REFUTED
the evidence says no
confidence 14/100
Scientific evidence directly refutes the idea that every human eye perceives the exact same visible light spectrum, as genetic variations, differences in retinal photopigments, and conditions like color blindness or tetrachromacy result in diverse color perception among individuals.
