Purpose: In this study, we investigated the effect of correlated color temperature and illuminance of LED lighting on change of the accommodative power and the phoria. Methods : We measured the accommodative power and the phoria for 26 students who aged from 20 to 34, when the light intensities (100 lux, 500 lux, 1,000 lux) and the correlated color temperature( 3,000[K], 5,600[K], 7,500[K], 11,000[K]) are changed. We used the Push up test to measure the accommodative power and the Near Howell phoria card to measure the phoria. Result: The effect of the accommodative power were shown to occur in the following order (1,000 lux > 500 lux > 100 lux), and (7,500[K] > 11,000[K] > 5,600[K] > 3,000[K]) (p<0.05). Light intensities and correlated color temperature had no specific tendency regarding phoria. Conclusion: This result showed that accommodative power varied depending on correlated color temperature and illuminance of LED lighting. The present study results provide good basic data for beneficial LED lighting conditions.
