How to identify "flicker" in sports field lighting?
Have you ever experienced eye strain, tearing, or dizziness after exercising for a long time in a sports field?
If this happens, it's likely that the lighting in your sports venue has a "flicker" problem.
In fact, the frequency of LED light source flickering is imperceptible to the human eye. Poor quality luminaires have a low refresh rate, resulting in a "flicker effect",
causing our pupillary sphincter muscles to constantly contract and relax, leading to headaches and eye fatigue; severe cases can even cause decreased vision and distraction.
However, our eyes cannot directly identify light flicker, making the harm of "flicker" difficult to prevent.
So how can we determine if a venue has flicker?
We can use a mobile phone to shoot a video of the venue. If the video shows obvious flicker in the venue, it indicates that the quality of the venue's lighting fixtures is not optimal.
To protect our eyes, we can reduce the time spent exercising in this venue, or move to a venue without flicker damage for exercise.
