The eyes of Deinopis spiders have phenomenal properties by spider standards. So far, 51 species of these spiders have been described.

An excerpt from the article 28 facts about spiders

Their central eyes are enlarged and point directly forward. Equipped with excellent lenses, they cover a very large field of view and collect more light than the eyes of owls or cats. This ability is due to the lack of a reflective membrane. The eye is not well protected and is seriously damaged every morning, but its regenerative properties are so outstanding that it regenerates quickly.

These spiders also do not have ears and they use the hairs on their legs to "listen" for prey. They can thus detect sounds within a two-meter radius.
