Yes Spiders have 8 eyes
Most spiders have eight simple eyes. [Insects on the other hand have large, compound eyes.] The two main eyes of a spider each have a simple lens, and a retina which is made up of light sensitive cells whose surfaces point toward he light as it enters the eye. These main eyes have a small field of vision with high resolution. They are especially well developed in jumping spiders. A spider's secondary eyes also have a lens but the light sensitive cells of these eyes point away from the light as do the similar cells in a human eye. The secondary eyes detect shadows and the difference between light and dark.

∙ 11y agoSome similar animals have many more legs than spiders, and some have only six legs. They are all animals that (a very long time ago) came out of the same family background. There are advantages to being like the spiders and having to main body segments and eight legs, or having very many body segments and very many legs, or having three body segments and six legs.
Given the body structure that spiders have, it would be problematical for them to have more than eight legs. If some kind of spider kept the same general proportions as the rest of the spiders but added two legs, then the legs would have to be thinner to fit. But some spiders already have legs that are too thin and break easily. Ten legs in the normal space for eight would probably make the spider too fragile to survive very well.
Given the way that some spiders hunt it is easy to see why there is an advantage to use all the space in the front half of the spider's two-part body for legs. When, for instance, a jumping spider wants to catch a fly, it spreads out its front four legs in preparation for snagging the fly as it lands, and then it jumps off using the power of the hind legs. If it used only two legs to jump with, it wouldn't jump as well, and if it used only two legs to grab with then it wouldn't catch things very well.
