Chronic IR exposure is a known occupational hazard that can cause cataracts. https://en.wikipedia.org/wiki/Glassblower's_cataract https://en.wikipedia.org/wiki/Glassblower's_cataract In the near future, you might not be able to look at a busy street without making visual contact with dozens of lidar scanners. It's already hard to avoid them in SF. The video referenced in TFA was filmed from about as close as you might be to a scanner while walking on the sidewalk beside a lidar-equipped vehicle. Cars can get very close to pedestrians in busy cities, e.g. at pedestrian crossings. Exposure is much stronger at close distances. Therefore I think there is a significant risk here that has not been studied or tested for in depth.
