Subject: BS: When yer arms shrink
For years I explained presbyopia as a combination of the lens in your eye becoming stiffer, and the muscles squeezing it lax. Both of which must be contributing.

But more recently I read that the eye keeps on growing, (as does ears & noses). Which would place the focal point away from the macular.

Apart from the obvious that presbyopia occurs long after the normal years of reproduction, what evolutionary pressures does it imply? Given that not everyone suffers from it.

It's one-eyed thought up earlier.
