Best Answer

yes they do they have great eyesight

'Several families of hunting spiders, such as jumping spiders and wolf spiders, have fair to excellent vision. The main pair of eyes in jumping spiders even see in color. Net-casting spiders have enormous, compound lenses that give a wide field of view and gather available light very efficiently. However, most spiders that lurk on flowers, webs, and other fixed locations waiting for prey tend to have very poor eyesight; instead they possess an extreme sensitivity to vibrations, which aids in prey capture. Vibration sensitive spiders can sense vibrations from such various mediums as the water surface, the soil or their silk threads. Also changes in the air pressure can be detected in the search for prey.

Spiders have two different types of eyes; pigment cup ocelli, which are only capable of detecting the direction of light, and the second pair are capable of forming images. The spider with the best vision is the jumping spider, which comparatively have 1/5th the power of vision of a human. So for their needs spiders eyes are enough to get the job done but do not have powerful vision.
