Figure 2. Refractive development in young rabbit over 12wk.

During the intervention, all rabbits had an emmetropization period with the decreasing of hyperopia. A: Refractive response of animals in NC group; B: Refraction of 8 young rabbits raised in HI group was higher hyperopia than that of animals raised in NC group; C: Refraction in MB group was closer to NC group; D: Refraction of animals in S-NL group was higher than NC group. NC: Less blue light at low illuminance group; MB: More blue light at low illuminance group; HI: Less blue light at high illuminance group; S-NL: More blue light at high illuminance group.
