In a second experiment (n = 19), a significant decrease in retinal vessel oxygen saturation was found in 100 cd/m 2 light compared to darkness but 1 and 10 cd/m 2 light had no significant effect.
Í annarri tilraun (n = 19) mældist marktækt minni súrefnismettun í sjónhimnuæðlingum í 100 cd/m 2 ljósi en í myrkri. Ljós af styrknum 1 eða 10 cd/m 2 hafði engin marktæk áhrif.
