do you think that getting a simple trial lens set and sitting in front
of an acuity chart under bright light will give you a good refraction?
do you think that there are any other refractive problems aside from
simple myopia? don't you think that ciliary muscle contraction and
pseudomyopia have any influence in a persons day-to-day visual acuity?



A trial lens set will give you an estimate. So will measuring how far
away you can see clearly. A professional eye doctor will give me an
exact manifast and cycloplegic refraction using his phororaptor. By the
way, a proper refraction should be taken in a dimly lit room because
bright light can skew the results due to pinhole effect. my
pseudomyopia is the main reason why I want atropine cycloplegia.

who cares about meeting this minimum visual acuity requirement.
somehow you think this BMV-derived standard is the only level of acuity
that we should attempt to attain. seeing 20/40 sucks, especially when
you're driving on a winding two-lane road at night in the rain.


In Otis' defense, I think he means that WITHOUT correction. If your
eyes are that bad for full time correction then it makes sense to
correct you best as possible, but an undercorrection is a good idea for
close work like reading, eating, computer or to relieve tonic
accomodation. But if your eyes arent bad, why bother with the wretched
minus lens which will just make your eyes worse and cause tonic
accomodation?

I think it would be a better "learning" path that to attempt
anything with atropine-sulfate.


who cares what you think?

Further, some people have a "reaction" to that drug -- and I think
and ophthamologist would warn you about these "secondary" effects.


and plus lenses induce diplopia in some people too.



Ill take my chances with cycloplegia in order to improve my vision and
do away with tonic accomodation which is a real problem for me as I
cant see well from near with glasses. Its either that or presbyopia and
I sure hope I am not presbyopic at 24!



Anon, then ill just use a 4 day regime. Am I supposed to return to the
doctors office immediately after the final dosage on the 4th day? How
long does it take for cycloplegia to start wearing off? If any tonic
accomodation returns after my atropine wears off, ill just exercise it
away. Ill be wearing glasses that correct my true axial myopia.
