They all come with thin rubber fold up eyecups (which fold down when the dust cap is on). The 32 and 20mm eyepieces are easy and comfortable to use and have enough eye relief that you can use them with eyeglasses if you are willing to accept a slight reduction in field of view. The 6mm eyepieces has a smaller exit pupal, and you will need to get your eye very close to them, so you won't be able to easily use glasses with it. I tested them with a 66mm aperture refactor (400mm focal length) and they worked very will paired with this telescope. They worked great in the day as a spotting scope and gave great views of the moon at night. I'm in a Bortle 7 area so have lots of light pollution, but all but the brightest stars were very sharp. (The brightest stars had some very minimal diffraction spike type effects.) Although basic and not an upgrade from a "brand name" eyepeiece, they provide very good value at this price point.
