    I am 43 and starting to have difficulties reading close. From what I
    understand, this gets worse with age until you completely lose the
    ability to accommodate. So, I got to wondering:

    1. Typically, at what age do emmetropic people lose ALL ability to
    accommodate?

    2. Assuming that you are perfectly emmetropic and have completely lost
    the ability to accomodate, what is the nearest that you can look at an
    object, and have it still be completely in focus?

    Thanks,

    Sometime between 45 and 55, 48 to 50 is typical.

    This depends upon the size of the object and your pupil size. Pupil size
    depends upon your individual make up, your excitement level and the amount
    of light reflecting off the object of regard.
