Yi-Hsuan Chou;Liu-Fang Hsieh;Chih-Chi Lin;Jia-Wei Huang;Jing-Hsiu Chen;Ya-Chen Hsieh;Ming-Li Chou;Po-Ting Yeh;Jwo-Huei Jou

From elementary school to university, font size of textbook is getting smaller, making reading harder. We found the illuminance required for reading increases with the decreases of font size, which might cause more damage to retina and more suppression of melatonin generation. Reading with blue light-less is much more friendly.
