Overview :
o-Reading is a simplified professional illumination meter for special activities (for reading). It flashes different colored LEDs according the illumination levels that are suggested in standards CIE, IES, JIS and CNS.

As we know myopia rates are higher than ever before. Although genetic factors can not be changed, we can improve our living environments, including home, school, office, etc. There is no way of knowing the light quality of our environment without a professional illumination meter(lux meter). Even if you have a lux meter, you can't tell if there is light flickering that will cause your eye muscles to tire more easily.

he method to use o-Reading is very easy: just aim the sensor at light, then press and hold the power switch in the center (icon of oTHE). For the first second, the LEDs will flash, and the o-Reading will perform self-test. After self-tested, the LEDs will flash by different environment light condition. If the red LED flashes, it means the ambient light is too dark or too bright. It is not suitable for reading. If the green LED flashes, it means the ambient light is between 300~1000 lx. It is suitable for reading. The yellow LED is indicator for light flicker. If the yellow LED flashes, the lamp may be near end of life, or the lamp is not so good in stabilizing the emission of light.
