Randomized Trial of Reading Lamp Colour Temperature Effects on Childhood Eye Development Ages 4 to 18

What this Trial Is About

Researchers are conducting a 12-month randomized controlled trial to examine how the colour temperature of reading lamps affects the development of refractive errors in children aged 4 to 18 years. Myopia, or nearsightedness, has become common worldwide, especially in East Asia, with many school-aged children affected. This study aims to explore whether different lamp colours can influence eye development during reading. Participants will be randomly assigned to use reading lamps with one of three colour temperatures 3000K, 4500K, or 6500K. These lamps have custom-made circuits to emit light at the specified colour temperatures. Each child will use their assigned lamp daily over the 12-month period to assess its impact on eye growth and refractive error. During the study, childrens refractive error and axial length of the eye will be measured up to 12 months. Colour vision will also be assessed as a secondary outcome. The study uses double masking to reduce bias, and participants will be monitored regularly to track changes. The total duration for participation is one year.
