  • A third idea is that sunlight is much, much brighter than most indoor artificial light, and the lack of this very bright light causes some sort of problem for the developing eye. Maybe the brightness of the sun is a sort of “calibration” method for the eye and when it doesn’t get that really bright sunlight, the development of the eye goes out of whack.

    So is it vitamin D, or far-away views or bright sunlight? I’ve heard all these theories before but I’m not sure which is it. Does the meta analysis say anything about which effect is most likely the cause? I mean could we “fix” this by going outside to view things far away, or should we just take vitamin D supplements, or should we have much brighter indoor lighting? I’d love to know.
