Lens Efficacy Video Experiment

Aim of the experiment: To figure out the lens efficacy in terms of blocking the blue light & UV ray.

Objects/ Tools used: UV (Ultraviolet) cum Blue light torch, Photochromatic Lens, Anti blue light lenses that Zebriana® uses in the computer glasses.

Method: First of all UV/ Blue light was pointed on the photo-chromatic lens and it turns darker. Then an anti blue light/ anti UV lens was placed over the photo-chromatic lens and again the light was pointed but this time it was observed that the light could not pass through the lenses.

 

RESULT :- Lenses of Zebriana computer glasses successfully passed the blue light test and were found appropriate for users who spend hours in front of digital screens that produce blue & UV light.
