Bats are not blind. Animals which live in caves and never come out are blind, like some fish and salamanders. Animals which live on the bottom of the ocean and never have any light are blind. Some moles and shrews are nearly blind.
Some of them are blind. and the other animals have their own light source; One of them is the Dragonfish.

Animals actually do have blind spots. For example, a horse has a blind spot directly in front of it that grows smaller the closer you get.
Blind animals have great hearing so they hear when something or someone is approaching.But most of blind animals have to be put down if found. Like old dogs :<.
They are not really night blind but they are diurnal animals.

Generally, no.
The ones that can see.
A blind is a covering for a window which allows light to be kept out.
If the dog is truly blind, it will not see ANY light, so the light will mean nothing.
