After getting my eyes dilated during a routine eye exam yesterday, Paige Paddock, my eye doctor, gave me some good feedback about the benefits of which tint to choose for sunglasses. I needed to make a new pair, as my prescription just changed again. Another friendly reminder from the big guy upstairs that I will be turning 40 in a few weeks and that gravity sucks big time on all of our eyes. Enough to gradually cause my eyes to develop astigmatism, pulling my eyes out of visual alignment. Time to move to zero gravity--is there a cabin available on the promenade deck of the International Space Station? Might need it soon...
But here is what she had to say on which color tint to choose:
---------------------------
Gray and Gray-Green tints: The most common type of lens color. Transmits all colors evenly without changing value of color. Light enough not to impair vision, yet dark enough to provide overall protection from glare. Excellent for bright sunny days. Grey tint is best for bright light situations like water sports because it blocks out the brightest of the sun's rays.
Dark Amber or Brown lens tints: A warmer, slightly brighter lens than the gray. Especially good at blocking the blue light commonly found in diffused light such as one might experience on a cloudy day. Brown/Amber can improve both contrast and depth perception, reduce glare and is a good all-around choice if you live in an area with changeable weather patterns. Brown is great for applications where distances need to be constantly judged, like tennis or golf or skiing or other sports requiring acute visual perception and contrast differentiation. Brown is also best for lower light situations, like fishing in the late afternoon or early morning. Brow
nish tint lens helps highlight the different contrasts in green colors and enhance visual acuity on the golf course.--------------------------
I would also add that polarized lenses are a major obstacle to professional photography. Any of you who have shot weddings or any portrait session outdoors on a sunny day while wearing polarized lenses know that you can not view your LCD on the back of your camera. So you have to go with your regular glasses and squint. For long bridal formals, eye strain gets to be a big problem. It is because the LCD screen is also polarized that when the 2 polarizations (glasses and the LCD) intersect, you won't see a thing on your LCD screen. So I will be switching to a tinted lens this time, most likely a brown/amber color.
Nikon/Canon: any new technology on the way that will improve the polarization on LCD screens so this won't be a problem in the future?
