I've had high myopia since childhood and for me the effect hasn't diminished (comparing between my annual checkups). I don't know any reliable statistics for this, however, only anecdotal experiences and consultations with my various ophtalmologists over the years. Do note that I'm only talking about cases of high myopia (in the 6-12D range at least), I don't know if the effect is as perceptible to someone with better eyesight.
