(Myopia prevention) Reduction in myopia progression is age and dose dependent.  (The younger the age the
lower the response to given dosage.)3 The 0.05% concentration provides about twice the
protective effect as the 0.01% solution1.    Rebound after cessation can be avoided with
a  taper  regardless  of dosage used4.    Although  slight  mydriasis  is  present  with  low
dosages5(0.01% to 0.05%),  problematic photophobia and cycloplegia is generally absent1, 8.
With higher concentrations (0.5% or 1%)  these side effects should be addressed with
progressive and photochromic lenses.
