Hello,
I am (easily) confused, so please humor me.
I was reading an article that stated that a patient who is using a +1.50 add is actually using +2.50 of power, +1.00 of that coming from the eye's accomodative reserve. ( This is at 16 inches ).
Even at twice the distance (32 inches), that half the add is used, it still states that +1.00 is used from the eye itself.
The confusion is at:
A +1.75D add wearer gets +1.75 from the add, +0.75D from the eye’s reserve.
Why is it not +1.00?
How is it determined how much 'accomodative reserve' power the eye is using?
I'm sure this is probably a simple answer and I'm making it much more involved.
This is almost too embarassing to ask, but hey...it's another thing to learn..
