Subject: Who can make themselves successful?
Item: Are all claims fraud? Who do you believe? Who makes the successful measurement? You, personally, or do you rely on a optometrist in an office?
I personally do not advocate that a person "attempt prevention", unless he can still read the 20/40 to 20/70 line (at the outside). Here is some commentary on this issue of failure.
http://frauenfeldclinic.com/transient-axial-length-change-mainstream-ophthalmologists-dont-understand-myopia/Virtually all ODs and MDs will tell you that prevention (from 20/50) is impossible? But is prevention possible. If so, who exactly makes that judgement.
A lot of people, "talk" about prevention, but then do nothing about it.
