It's a tricky question because insects have two kinds of eyes. There are simple eyes and compound eyes. Some insects just have one type, others have both types. The simple answer is, most insects have two eyes, but several of them have five eyes.
Antennae and compound eyes are appendages that insects have and that arachnids lack.Specifically, insects have three (3) pairs of legs and one (1) pair of antennae. In contrast, spiders have four (4) sets of legs and no antennae. They also see through a series of singular, lensed eyes whereas insects have compound eyes.

No vertebrates have compound eyes. Compound eyes are only seen in invertebrates, mostly insects.
Insects can have a number of eyes and moreover, eyes of different types; single eyes and compound ones. In contrast with our eyes, insect eyes are immovable and unable to focus. Insects are short sighted. Butterflies are probably the most far sighted, they can see perhaps a few meters, while bumblebees only have a range of a half meter. But many insects are helped a lot by their sometimes unbelievable sensitivity for scents.
