Are you legally obligated to remove your gles and submit to an "eye test" when pulled over by police?

when you are stopped by police are you legally obligated to take an eye test? (when they shine their flashlight in your eyes and look for possible involuntary drug induced motions) or can you as with field sobriety test and breathalyzer at the scene, you can quote your 4th amendment rights and deny their attempt at illegal search and seizure...i'm very interested...please respond with factual information and sources to back it up.
