The human body is built to need light to see. Without light one can overbalance. During the last war when Britain had a total black out in the streets, people walked into each other on the pavement/side-walk.
I was looking at the old newspapers about it the other day.
You need good light to be able to read,,how much depending on ones eye sight.
because we see when our retina collects light..when there’s no light reflecting off of things, we can’t see….but you know even when the lights are off…we can see little bit after we adjust to the darkness…because our color blind rods become active at the time…
Light has to reflect off an object in order for us to see it. No light, no reflecting. What are they teaching in science class these days?
Because it is dark like Obama’s soul!
