Eye pixel comparison: the recently discovered fossil eyes would have seen the world with over 3000 pixels (centre image), giving its owner a huge visual advantage over its contemporaries, which would have seen a very blurry world with about 100 pixels (left image). This is much better than the living horseshoe crab, which sees the world as 1000 pixels, but not as good as living dragonflies, which have the best compound eyes and see the world as ~28,000 pixels (right image).
