Question:
Anyone know about this effect or where I can find more information on it?
Answer:
Your optometrist is correct, it is called cataract myopic shift. Your
presbyopia has not reduced however, it is your hyperopia that has reduced.
As the lens in the eye ages it becomes more dense and changes refractive
index and effective power. An increase in power means more myopia or less
hyperopia, thus your driving glasses now work as readers. This is the same
process that eventually results in cataract, cataract are a normal result of
the aging process. This certainly happened to me. The nonuniformity showed up by my seeing
multiple images. I called it a fly's eye phenomenon because I had no better
term to use for it.
I still had remanents of this fly's eye image after implantation of a lens
during cataract surgery. I still would like to have an explanation on why
the multiple images were formed by the impland and why they went away with
porperly fitted glasses.
