polarized vs. polycarbonate
 
Not sure if this is the right place to put this. Mods, if this is the wrong place, plz move.

Okay. So I saw the ad for Redstar World Wear's free sunglasses trial. I'm very tempted to get a pair since all I need to pay is just shipping. But i'm indecisive about the lens type. There's an option for Polarized or Polycarbonate.

I did some googling. From what I get of it, polarized is better for canceling out glares but polycarbonate is good against impact, thus safer if u were to be in an accident. Is that correct? What are others pros/cons of both lens types?

edit: and i misspelled polarized in the title. Can't change it. Hmm.. :innocent:

Polarized is better for glare but it can also make it difficult to read some some lcd screens on cycle computers, cell phones, etc.

I would avoid this sunglass promotion. You will get what you pay for. Did you notice your S&H also included "profit" in the small print. You have no idea about the optical quality, quality in general, impact resistance..... It's your eyes for goodness sake. Buy glasses from a know brand like, Smith, Uvex, WileyX, Oakley and many others.

Got any info on the free trial? I went to the website and excuse me for my skepticism, but it seems like a scam to get you to buy cheap sunglasses through shipping and handling charges. "$190" interchangeable lens glasses for $19 shipping and handling. I can buy them for less on DealExtreme. Of course, if they are optical quality a la name-brand glasses such as Oakly, that is a different story.

Polarized lenses, while they do reduce glare, are designed to filter out reflections. This is good if you ride, say, next to water a lot.

Non-polarized lenses reduce glare or not depending on the quality of the lens. I've had some amber lens sunglasses that performed better than some polarized lenses in that regard, and some that would flare up like a lightning bolt the second the sun hits the lens directly. It's a crapshoot. That's (one of the reasons) why it's always best to try sunglasses in person.

Someone on BF recommended these:

They are great. Very light weight and cheap enough to get multiple pairs. I have clear, yellow (awesome for riding at night), blue block (great for foggy/hazy days), gray and mirrored.

I use them for road rides, commuting, MTBing and anything else on the bike. They've held up well and I like them much better than the Bolles I was using prior. The wrap gives great peripheral vision and they don't have a bridge so nothing gets in the way of your sight-line when in the drops.

They also come in smaller size (mini-magnum) and I set my wife up with several pairs. My 88 year old M-I-L tried on one pair of my wife's (mirrored) and had me order a pair for her. She loves them and they even hold up to her abuse.

Personally I think polarized lenses are largely a marketing gimmick. I like them for driving because they cut reflections from the windshield, but they aren't of much benefit elsewhere. Bear in mind polycarbonate is just the material. You can have polarized polycarbonate.

The biggest thing I have found with sunglasses is that you really get what you pay for. Cheap junk gives you very poor clarity and will not last. Buy quality optics and you will "see" there is a world of difference. This matters a heck of a lot more than whether or not the lens is polarized.

Right now I use mainly the Smith Pivlock V90 for biking (dorky but effective) and a pair of Smith Threshold polarized glasses for general use. I didn't actually want the polarized lens, but I got a good deal and they are very high quality.

As far as $5 glasses go, you're absolutely correct.

If you're a fisherman, you kayak, anything on the water, polarized lenses are worth their weight in gold. Good ones, that is.

I don't think polarized lenses are something you really need for cycling though. Heard somebody say that polarized lenses also "smooth out" the appearance of road surfaces too, which if you're on dicey pavement you might miss shards of glass or the like. Not good.

That's what I noticed. It seems that I can read the road better with non-polarized glasses, especially if it's a bit wet.
OTOH, while fishing, it would be a significant handicap if I did not have polarized glasses.

I have 2 pair of Rudy Project sunglasses, both have polarized lenses. One pair has polycarbonate (pc) lens, the other does not. The optician who made the lens for the pair without polycarbonate said the lens could shatter easier than the pc lens. The reason I got the second pair is I wanted the tint darker than the first pair and apparently it couldn't be done on pc. I don't think polycarbonate and polarized are mutually exclusive.

I like polarized glasses...RayBan Wayfarers.

thanks for the responses guys.

The ad definitely sounds like a scam. I was skeptical. But then I found it in Bicycling magazine so I'm not entirely sure. Today I tried googling the company, here's some responses from woot:

So i guess in short, the wait is long and the quality is okay.

But thanks for the responses on polarized vs. polycarbonate. I guess in the streets of nyc, polarized will not be good for looking out for bunch of shattered glass then.

baldsue, how do u like the Rudy's? I really like rudy helmets and i know they started as a glasses company so i'm quite interested in them.

I saw it on the Internet, so it must be true.:twitchy:

As Seen on TV!!!!:eek:

Free glasses! *

An essentially dishonest business model.

I don't know about where you're getting the glasses from, but the optical shops I use for prescription glasses can get polarized polycarbonate.
