    Polarized sunglasses - a bad thing

    I saw the prettiest colors today.

    I'd heard enough warnings about how oddly polarized sunglasses interact with faceshields. I also tend to buy cheap sunglasses because I'm very good at leaving them on the rear seat as I pull out of the parking lot.

    I bought a new pair of -gasp- $20 sunglasses. I made sure they weren't marked "polarized". But they were. Looking through the new glasses and the faceshield revealed a distracting world of rainbows and spacial ambiguity.

    The glasses go back tomorrow (REI).

    Just another data point and warning.

    In my brief riding career, I've noticed the same thing. My biggest distraction has been the patterns in the windshield that polarized sunglasses reveal. I've also been told that polarization can reduce or eliminate reflections that might indicate oil, glass or other reflective surfaces on the road - not a good thing for a 2 wheeler.

    Yep, if you like psychedelics, all you need are polarized glasses, tinted visors or windows like in a cage , chemical enhancers and off you go
    All kidding aside, polarized glasses will hide oil spots on the road too so be carefull what you wear.

    Hello; I was talking to a friend recently who told me about his detached retina experiences. He said when it was all over he ended up with double vision because the retina was re-attached at a different place. His specialist said for him not to worry about it, that his brain would make the correction for him. Now when you look at him you can see that one eye is lower then the other and off to the right. That is how the brain adjusts to the new retina position. The point is that the brain rapidly adjusts to changes in our vision, sometimes without our even noticing the difference.

    I have polarized sunglasses that magnetically clip onto my eye glasses, at first I thought that the colours were a little weird, with some trees glowing brightly, and with spots on the road that only one eye could see. After a month of use, I could barely see the difference, I guess my brain filtered out the importance of the colour change.

    I suppose that some people can adapt and some others cannot, or will not.

    Donkey,

    It's fascinating how we adapt. One of the more notable experiments is the fitting of a visor with a mirror that flips the view of everything. At first simple tasks like pouring water into a glass is nearly impossible. At some point, it's as though a switch is flipped and everything, through the new view, is 'natural'. The return to normal vision is just as challenging.

    I won't use the polarized glasses because 1. it makes crazy lighting effects. being able to see everything as they are is very important to me (see profile). 2. the RID display on my GS is unreadable when seen through the glasses and faceshield. 3. A wet manhole cover looked oddly gray and blended even more into the road surface.!!!

    Yup the human ability to adapt is pretty amazing.

    I however use polarized suunglasses, and find my vision improved over non polarized, once I got used to them. They are an improvement over the squinting effects from the contacts.

    Might have something to do with the fact one eye is 20/450 uncorrected. Needless to say that contact has some power to it. The trade off for me was worth it, but I knew I was making the trade off.

    What works for some might not work for all. Just be aware of the risks and changes that polarization can make.

    Unhappy Hard to see

    I have a pair of the magnetic clip-on sunglasses also, and I get all the psychedelic color moires with my visor down (makes car windshields look gold and/or purple), PLUS the polarization interferes with my GPS and XM screens. Sometimes, I have to twist my head 40 degrees to be able to make the GPS seem anything other than black.

    Obviously, not a safe situation.

    I'm thinking of asking the local eyewear shop to grind a set of plain tinted lenses for my clip-on frames.

    I used to relay entirely on cheap sunglasses too, Knary, but not anymore (although I have a few pairs as emergency spares). You see, a few years ago I underwent LASIK and during the healing time, I needed to have sunglasses that kind of wrapped around (which I did not have) to keep debris out and I was cautioned by the doctor to buy high quality ones since I would have to wear them a lot and so forth (cant recall the other reasons). Anyhow, off to a big mall I went and bought a set of Revo "Mad Wrap" sunglasses. These glasses absolutely ROCK. I'm not kidding. The visual clarity is unbelievable - kind of like the difference between cheap binoculars and really expensive ones, if you have had that experience. I think Revo had something to do with the coatings used on our astronaut faceshields(?).

    Now I am completely ruined for cheap sunglasses because as soon as I put them on I can see how crappy my vision becomes. I used to be unable to imagine that expensive sunglasses could be worth the money, but at least some of them can. I was totally surprised by this.

    Revos are better for your eye's health as well. They not only block ultraviolet rays but also IR. Cheap sunglasses don't do that. Worse, since they're likely dark, your eyes open up and then they take in more UV and IR than they would if you weren't wearing the sunglasses at all.

    Now that you say that, I think those were some of the things my eye doctor said to me as well.

    I wear a pair of Revo prescription sunglasses and never have the polarizing problems described above. A little rainbow pattern on my windshield but thats about it.. The clarity of Revos is truly eye opening.

    I've noted a definite difference in quality between the truly cheap and other sunglasses. I think you are right. I think I should just bite the bullet and buy something of some level of quality. The optics are better and the level of tint is often more appropriate for driving/riding. I *hate* how most cheap sunglasses are incredibly dark, making them unusable for me in all but the darkest situations.

    p.s. the polarized lenses made my bike's RID completely unreadable.
