Here in California they're called "Bott's Dots" -- non reflective raised markers used to let the driver know when he's going out of the lane. They're named after Dr. Elbert Dysart Botts, a California Department of Transportation (Caltrans) engineer credited with overseeing the research that led to the development of the markers and the epoxy used to attach them to the road. About every 4th to 6th dot is a reflective marker, also epoxied to the roadbet, which I think you're referring to as "cats eyes".
