Based on a 2022 research published in Science Advances, mitochondria enable transform light-weight into neural signals, which are interpreted by the mind. 

Mitochondria: Excess Eye Lenses

Acting as little eye lenses, the mitochondria focuses gentle from the surroundings onto a slim tissue layer recognised as the retina. In the retina, photoreceptor cells take up the mild and translate it into nerve signals that are sent to the brain, and transformed into the pictures we see.

Prof. Jeffery points out that “the wonderful detail about the retina is that it has a lot more mitochondria than any other organ mainly because it employs so substantially strength.” Because you are in a position to place mild directly on to retinal mitochondria, this can make red light-weight therapy helpful in aiding eye treatment, precisely, fighting from macular degeneration.
