In the great sunglass marketing scam, tests continually show little real difference in glare reduction between the cheapies and the $200 options. And glare reduction is the name of the game.
You must use polarized glasses to reduce glare. Different colors may give you greater contrast and may make you more comfortable in various conditions but polarized lens will not only reduce glare but will protect your eyes as well.
In spite of religiously wearing polarized sunglasses during twenty years at sea my eyes are now much more sensitive to glare and harsh light than they ever were before. And I used to wear the high dollar versions back when cost was no object. I switched when I found that a cheap pair of "fish-finders" did as well as whatever the current $200 rage was at the time.
I had to work in conditions where the damage to my eyes was an inevitable occupational hazard, most of you do not. I'd strongly encourage you to make use of polarized lenses; your eyes will thank you later. And they're so cheap there's no reason not to do so. Look for polarized first, then you can go for all the bells and whistles your pocketbook or vanity desires.
Btw, you can tell if a lens is polarized, right from within the store, by looking at the glare outside, say off the hood of a car. Hold the lens out six inches from your eye and look at the glare. Then rotate the lens ninety degrees. Depending on what angle you started from, you'll see either a marked increase or a marked reduction in the glare. If it stays the same, the lenses are not polarized.
