Brief Summary:
Previous studies have shown that the spectrum of light influences myopia LED lights with a partially absent light spectrum increase the risk of myopia progression compared to LEDs with a full spectrum potentially mediated by the excitability of the parasympathetic nervous system This study intends to compare pupil size and area as well as parameters regulated by the autonomic nervous system such as skin bioelectrical activity and heart rate between LEDs with a full visible spectrum and LEDs with a partially absent spectrum around 470nm and 730nm We aim to elucidate the physiological mechanism underlying the effect of light spectrum on pupil changes and myopia
