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. |

They have not tested this on people over 100 or dolphins so I hope it works for me. The dehydrating aspect to these eye drops may be of unique benefit for Fuch's syndrome of too much fluid in the eye. |

One way menopause did contribute to evolution - (eg) Downs Syndrome is more of a risk to older mums. So not reproducing at a age of risk frees the tribe of caring for less able members. If you are a hunter-gatherer, these things are not inconsequential. And the eyes have it - there was a New Scientist article from an Italian ophthalmologist who reckoned the opticians' world were prescribing too perfect lenses which didn't allow the eye muscles to exercise. But that was good for business as the eyes got lazy! As eye see it............. I'll get my coat |

Had the toric lenses installed, even though Medicare didn't cover them and I paid for them myself. It corrected my eyes to 20/25 in each eye, instead of the results of the uncorrected amblyopia I'd suffered with for since I was about 7 years old. |

Recovery time can be days. it is the improved version of cornea transplants that fail over time. This new method is 94% successful. I read all the side effects for vuity eye drops that replace reading glasses. thumbs down imo |
