Exposure to 7∶7 or 1∶1 min bright light cycles inhibited axial eye growth more than constant bright light (all P<0.05, except for the comparison between the 7∶7 minute cycle and the 5 h constant bright light exposure, P = 0.180 and a borderline significance between the 7∶7 minute cycle and the 1 h constant bright light exposure, P = 0.075).
