contrast sensitivity

    I'm a 43 yr old who is addicted to tennis. On a bright sunny day, I can see
    the ball clearly from the other end of the court all the way to my end of
    the court. Yet, when the skies are overcast, I don't see the ball clearly
    across its entire path. Depending on the background, I may lose it for
    fractions of time. I may lose it in the other players white shirt, in the
    white lines on the court, or in the white tape across the top of the net.

    I also have difficult seeing the ball when the background is a parking lot
    full of cars and the resulting reflections of the sun that come off the
    cars. And I have some difficulties seeing it while playing indoors under
    artificial lighting.

    I generally still hit the ball under these conditions, but I'm much more
    defensive. I've been to the eye doctor and he says that my eyes are
    healthy. I have an updated set of contact lens (rigid gas permeable) that
    gives me sharp focus, but it appears that it is a 'contrast sensitivity'
    issue. There is some degrees of color blindness in my family. I've passed
    the simple color blindness tests at the eye doctors, but have noted that
    some of the colored images don't 'pop out' to me where they do to my eye
    doctor.

    Any thoughts or suggestions would be appreciated.

    You might try using lenses with a special tint to give the fluorescent
    green tennis ball a little more contrast.
