If you have no eyes, then there will be no sprouts from that piece. The idea is to cut them into pieces with a minimum of one eye per piece. If the potatoes were not treated the eyeless pieces could be cooked. Back in the WWII years it was common practice to take large potatoes cut out a golf ball sized chuck (actually they said Guinea egg size) containing eye(s) and cook the remainder when all the eyes had been removed.
