It's a long video. One can watch from the time stamped portion of the video above.

Short story is that high luminosity blue light can likely prevent near nearsightedness which could potentially cause a permanent damage to eye in certain cases, especially retinal detachment.

Playing outside under the sun for 1 - 2 hours can go a long way in preventing near nearsightedness. So involve kids in sport activities or have a picnic outside frequently.
