    Neil, my goodness....just answer the hard can it be
    (whether relevant or not)? Certainly a person who thought it
    irrelevant would respond anyway! I mean, your name calling is
    irrelevant, but yet you consistently engage in this irrelevant act

    Plus lenses were not used in the O'Leary study.

    Undercorrection of myopia is similar to the full time use of low power
    plus lenses and similar to not using minus. This was only one study,
    with a small number of subjects. It was repeated once and there was
    no difference in the progression rate between the groups.

    Taken together with Parnissen's study, the three studies throw a lot
    of cold water on the idea that wearing minus causes myopia
