These larger bats can actually see quite well, especially at night. Their eyes appear oversized relative to their heads, are forward-facing, and give the bats binocular vision. They also have mirror-like retinas that reflect and capture the limited available light. Microbats, on the other hand, have underdeveloped vision. The little brown bat, the most common in the U.S., relies on echolocation to hunt prey and avoid obstacles instead of eyesight. Their vision is just sharp enough to allow them to see beyond the scope of their echolocation.
