As blind as a bat?

Not true, in fact bats have quite good eyesight, especially at dusk. Fruit bats have large eyes which gather in a lot of light giving them good night vision to find their food. Microbats, although possessing reasonable eyesight from their much smaller eyes, have a much more efficient method of finding their way in the dark called echolocation. They shout extremely loudly, at frequencies too high for us to hear, and listen for the returning echoes. The echo gives them all the information they need about their surroundings and where their food is. It really is amazing that a bat can locate, whilst flying, a tiny flying insect in total darkness.
