    I am interested in your opinions on picking a good pair of sunglasses.

    First let me ask you this;

    Thomas Quackenbush says in his Bates book that eyes are organs that need
    light to work and using dark lenses reduce the ability of eyes to work
    correctly so he never uses them and his light tolerance increased. I
    agree we work longer hours indoors without natural light and all that,
    but what about the UV? I don't remember him commenting on the UV issue.

    I recently grabbed one of those amber tinted sunglasses which was made
    by Ironman and it is 100% UV protected. I also have a Blublocker driving
    pair ... I bought them after witnessing that these type of visors are in
    use with the USAF...

    I seem to have better vision with amber ones during very sunny days
    without the much squinting...

    I appreciate your comments...

  2. What year was it written? We've only recently learned about the harm of
    UV and the blue light problems. Indeed we need light for our eyes to
    work, but "dark" glasses are good for when there is too much light, so
    long as they block UV.

    I'm not sure how much of the apparent increase in contrast sensitivity
    with blue blockers is real and how much is imagined, but in general it
    seems to be a good thing. Probably the worst thing to do would be to
    get a dark pair that didn't block UV.

    I'm not in favor of the very dark, dark sunglasses except for rare uses
    (like mountain climbing), because they can be dangerous when in shadows.

    First in 1997 and again revised in 1999 I believe...

  4. Oh well then he ought to know about UV causing damage to corena,
    crystalline lens, and retina, not to mention skin. Sounds like maybe he
    is ignoring the vast information available and chosing to try to
    resurrect an old theory long since discarded by mainstream science.
    Like Bates. Like iridology. Like flat earth... you get the picture.

    A lot of those old theories have a certain lure to them because they
    seem so simple and the espousers seem so certain and so trustworthy.
    Same reason old wives' tales persist. I mean you're not gonna trust
    your grandmother?

    Anyhow, I think it's a good idea to wear protection out in the direct
    sun, both for skin and eyes. But I don't lose any sleep over it. After
    all, we do wear out anyway, no matter how careful we are...
