Thread: Positive glasses

    Positive glasses

    I've reached the point of doing RB with positive glasses. I'm using +1.50 now. What is the maximum power of positive lenses that can be used for training? Thanks.

    There is no real maximum power, it is pretty much what ever feels comfortable for you, and allows you to read at a normal distance (around 19-20 inches).

    Thanks Jansen. I mean the maximum power without the risk of developping presbyobia.

    I don't quite happen to know much about presbyopia, except the fact that it develops as someone ages. It is usually caused by the ciliary muscles not being flexible enough to contract and relax. Note, that presbyopia and hyperopia (farsightedness) are actually different from each other in this aspect, as hyperopia is caused by a weakness in ocular muscles. I think if you constantly are switching focus between far and near in your normal routine, presbyopia shouldn't be too much of a concern, as switching focus between far and near distances exercises the ciliary muscle. Note, that presbyopia and hyperopia (farsightedness) are actually different from each As far as maximum power of plus lenses, i'm not completely sure, but it shouldn't be too much of a problem.
