Reply to comment by 69SadBoi69 in Is every single living cell adjacent to or “have access to” a capillary? Are there living cells not next to a blood/O2 source, and if so, how do they survive? by Friggin

If I recall correctly, we are currently going through a near-sightedness epidemic that is thought to be caused by things like not spending enough time outside in bright sunlight. Basically, our eyes need environmental cues to properly finish growing, and our modern lifestyles are stunting this growth and forcing more people to develop near-sightedness that would have otherwise had normal vision.
