Protect your eyes with the power of science
BenQ Optical Laboratory strives to research optimal light without harming the user's eyes.

A light with a reflectance as close to zero as possible

We conducted 320 hours of optical experiments and tested 100 million rays to find the optimal reflection angle. As a result, we were able to develop "asymmetric optics," a lighting technology that reduces reflections on the screen and is gentle on the eyes. In addition, we are investing in specialized equipment such as spectroscopes and luminance meters to improve the accuracy of our experiments.

Working with optical experts

A joint study with National Taiwan University of Science and Technology found that backlighting helps reduce eye fatigue. Of the 12 types of light, the majority of test participants said that the 12th lighting mode felt the least tiring. The 12th backlight is a combination of a 500Lux, 4000K supplementary front light.

Why 500 Lux and 4000K brightness?

Based on the US office lighting standards, we worked with our users to recreate these office lighting conditions. We found that 500Lux and 4000K color temperature light reduces eye fatigue and provides comfort. Therefore, our lights are designed to emit 500Lux and 4000K light in auto dimming mode.

LED light source with optimal safety

Our LED supplier is a global leader in optical semiconductor solutions, with the latest LED technology and in compliance with IEEE PAR1789 regulations on LED lighting flicker. Furthermore, the European Union assessments IEC/TR 62778 and IEC/TR62471 have determined that the LED light sources used by BenQ are safe for blue light. BenQ's pursuit of the highest quality light allows office spaces to be evenly illuminated, relieving eye fatigue and creating a more comfortable lighting life!
