I've heard some Opticians specify a minimum of 2 weeks use for a patient to try a new PAL lens.
I'm wondering what others think about this, and if it has any basis in scientific fact.
It seems to me there are 3 possible outcomes:
1) the patients body (eye/lens/muscle/etc) actually change shape so that the optical image is painted differently on the back of the eye. Seems unlikely.
2) the patients brain learns to correct poor image information (outside the sharp corridors of the PAL). Sounds not only unlikely but impossible.
3) the patient just learns to deal with a bad lens. I think this is what the real hope is for the Optician; that the patient just gives up and finds ways to deal with the poor image, by things such as bending their head around, carrying a 2nd pair of glasses, getting help from friends, etc.
So I'm wondering what other opinions are.
More importantly, what is the scientific basis for the "2-week" period, meaning point us to actual studies that show the results have a basis in physiology.
Thanks for other opinions and facts.
