The Wolf Spider, like most Araneae, has eight “simple” eyes, basically just organs that can detect light and darkness. Characteristically, the Wolf Spider’s eyes occur in three horizontal rows, with four small eyes in the bottom row, two large eyes in the middle row, and two medium-sized eyes in the top row.
Their eyes reflect light well, and one way of finding them is to hunt at night using a flashlight so that the light from the light is reflected from their eyes directly back toward its source.
The eye shine is caused by a tapetum [a membranous layer] in the eye which reflects light rays back through the eye retina and can possibly enhance the spider’s night vision.
hope this helps

Nothing, as far as I know. Sure Wolf spider eyes reflect light at night, but so do other simple eyes. Moths. for instance, produce a nice, bright eye reflection of varying colors (I like the red ones the best). Of course, larger night-active animals have eye-shine as well; cats being the classic example. I can't think of a single way that Wolf spider eyes are unique, either at night or in the daytime. Sorry! (Actually, you could make a case for the number of eyes, but I have to say that I've never really noticed a multiple sparkle when hunting by light at night - it's always been the 2 big ones that give them away)

The Wolf Spider has the largest eye-to-body ratio of any spider and therefore has the best night vision of any spider in the world. Their eyes both pick up and reflect light well so they actually appear to glow in the dark because they pick up the slightest bit of light and will reflect it. The glowing effect is actually just a slight reflection off the eyes though.
