Vision after cataract surgery

    At age 60 I had to use reading glasses. I am now 82 years old and due
    to clouding I had cataract surgery. I selected monovision, simply
    because that's what I had for the last two years. For reasons unknown
    to me one day I was able to read newspapers withouth glasses. My right
    eye stayed at far focal range and my left eye changed to close. I am
    perfectly happy with the replacement lenses, but as an engineer I am
    very unhappy that I have not the faintest clue why the brain is able to
    seamlessly switch from one eye to the other when the viewing distance
    changes. My eye surgeon hates engineers, he thinks they are like kids,
    they allways have to ask: WHY. Anybody knows WHY ?

    The second problem I have is: When I look at say 3 televison antenna
    towers in the distance, they are not straight up and parallel to each
    other, but they are slightly bent in relation to each other. The
    windows in a large building are not rectangular but have a hourglass
    contour in the vertical, with top and bottom at slightly different
    angles. While this does not bother me much it again brings up the WHY.
    If the lens used was a fresnel I could consider some kind of
    interference, but I am assured the lenses used are of the lenticular
    design, i.e. slightly thicker in the center than at the rim. Again,
    anybody knows of this?

    And Richard, if you do run across how the brain patches in the crazy quilt
    design into the blind spot....
    please let me know.
