I'm a bit late to the party, but I wouldn't worry much about “eyes” at all. Once you enter your dream state (and you will, eventually, once you've been asleep long enough), you'll see imagery, period. It will form all by itself without any need for you to do anything, just as it does in all nonlucid dreams. No need to be too concerned with what either your waking-life or dream body eyes are doing. If you've managed to properly keep lucidity until you reach REM, it should be obvious when you've entered your dream. In my experience, when I go from non-dream to dream state lucidly all I have to do is wait until I notice the dream world materialize around me, and once it appears reasonably stable and complete I'm ready to go and have fun.
