Concerts can't bring laser pointers because of the fear of shooting stars in the eye.
Laser is a powerful light, so when looking directly at it, the laser causes the death of retinal pigment and photoreceptor cells under the macula.
When these cells die, the macula has no photoreceptor function, and the macula is the place where vision is sharpest, and although it's only 3% of the entire retinal area, it plays a role in 90% of the entire retinal vision.
