Questions: How is accomodative amplitude measured? H.R measured 20/25
to 20/40(variable) at 30cm. Youd need 3.25 diopter accomodation to see
20/20 at 30cm. Yet hes NOT seeing this well. They said he gained 4
diopters of accomodation but it sounds like he has closer to 2 diopter
accomodation and experiences slight blur at 30cm. Maybe I am to assume
you cant use all your accomodative amplitude, some is "reserved"

I dont yet know if I have presbyopia(at age 24!) or just a large amount
of accomodative excess. My near vision monocularly(one eye) starts to
blur at 40cm with -5 distance correction. Binocularly(both eyes) I can
zoom down to 25cm with -5 distance correction. With less minus, my
distance vision decreases, my near vision increases. Uncorrected, the
worse eye sees optimally at 21cm near point(-4.75) So if a 24 year old
is supposed to have what? 8 diopter accomodative amplitude using
binocularly. I have demostrated about 4 to 4.5 diopters binocularly. I
am therefore "missing" another ~4 diopters. If its "locked" up in tonic
accomodation, then my cycloplegic refraction would be very, very close
to plano and just slightly myopic. If my cycloplegic isnt too much
lower than my manifast, presbyopia is the logical explanation.

Presbyopia at 24 huh?

You have no idea what you are talking about.

Here's a clue. presbyopia means "old eyes".  Unless you have
progeria, you do not have "old eyes"

We will see. If I dont have alot of accomodative spasms, whats the
other logical explanation? Ragnar, you can accomodate down to 4-6
inches and see 20/20 in distance. With glasses that correct all my
myopia, I can NOT see this close and im younger than you. I can see
this close only if I take my glasses off!
