Spirulina protected against light-induced impairment of visual function. (A) Representative waveforms from an individual mouse recorded by ERG 4 days after light exposure. (B, C) The amplitudes of both the a- and b-waves were reduced after light exposure, which were attenuated by dietary Spirulina supplementation. (D, E) The implicit times of the a- and b-waves were not changed. LE, light exposure. LE (–) + control diet; LE (+) + control diet; and LE (+) + Spirulina-supplemented diet. n = 5 in each group. **P < 0.01.
