Why does visible light not cause eye damage?

Since visible light is higher on the EM scale and has more energy than Infrared, then why does visible light not damage our eyes while infrared does (at long exposures)

Because you blink if it's too bright. Infrared doesn't make you blink. In fact, if you're in the dark, your iris could be wide open letting in more infrared. 

You start to notice problems after the damage is done. It needs to be very intense to cause damage. Anything which is incandescent enough to burn your eyes will also be bright in the visual range. 

If the source is a laser diode, there's increased danger because the coherent light can be focused onto a very small area.
