            Contact 
              lenses that can be safely worn for weeks or even months at a time 
              took a step closer to reality with a novel type of contact lens 
              recently tested at UC Berkeley. A team led by UC Berkeley vision 
              science professor Ken Polse and chemical engineering professor Clayton 
              Radke, also in Berkeley Lab's Earth Sciences Division, working 
              with former vision science graduate student Kimberly Miller, found 
              that placing fenestrations, or holes, in contact lenses significantly 
              improved tear-mixing, thought to be an important safety factor in 
              long-term contact lens wear. (02/12/03) Full
