Is blue light damage reversible?

The extra energy can be the reason for this chemical change causing retinal-generated toxicity. “Blue light appears to damage retinal cells. It is still unclear how much blue light and for how long it’s necessary to damage these sight-seeing cells. We do know the damage is irreversible,” said Dr.
