Basic arrangement of spider eyes, viewed from above. Most spiders have eight eyes, which tend to be arranged into two rows of four eyes on the head region. The eyes can be categorised by their location and are divided into the anterior median eyes (AME), anterior lateral eyes (ALE), posterior median eyes (PME), and posterior lateral eyes (PLE).
The specific arrangement of the eyes is one of the features used in classifying different species. Most species of the Haplogynae have six eyes, although some have eight (Plectreuridae), four (e.g., Tetrablemma) or even two (most Caponiidae). Sometimes one pair of eyes is better developed than the rest, or even, in some cave species, there are ...
This jumping spider's main ocelli (center pair) are very acute. The outer pair are "secondary eyes" and other pairs of secondary eyes are on the sides and top of its head. Spiders do not have compound eyes, but instead have several pairs of simple eyes with each pair adapted for a specific task or tasks.

[25] Eyes of the jumping spider, Plexippus paykulli Spiders have primarily four pairs of eyes on the top-front area of the cephalothorax, arranged in patterns that vary from one family to another.

Eyes: The basic number of eyes is eight, typically arranged in two rows (e.g. as in Gnaphosidae); the front row are the anterior eyes, the row behind the posterior eyes; the four eyes to the edges are the lateral eyes, the four eyes in the centre the median eyes; the anterior median eyes are called the main eyes or direct eyes, while the other ...

Their eye pattern is the clearest single identifying characteristic. They have eight eyes, as illustrated. [3] [4] Most diagnostic are the front row of four eyes, in which the anterior median pair are more dramatically prominent than any other spider eyes apart from the posterior median eyes of the Deinopidae. There is, however, a radical ...
