Yeah, you do a depth perception test, color, near, far, and everything inbetween. My depth perception test had about 20 rows of 5 rings in each row 1 of the 5 rings was slighly closer than the others. I had a problem with it but passed. Some other guys have said that if you close your eyes and open them, the closer rings will stand out. I've also heard that if you move your head around a bit during the test you can see the closer rings move and the further ones don't
