Sunglasses

[sanemax]

I want to buy some new sunglasses .

I want them to protect my eyes .

There are 30 Baht ones from the market and 3000 baht ones from an optician and various other prices in between . 

   Is there anyway to tell which pair of sunglasses offers U.V protection ?

The 30 baht market ones are just darkened plastic that offer no eye protection and actually cause eye damage .

   The more expensive ones have a "U.V protection " sticker on them .

But there would be nothing to stop a shop getting cheap sunglasses and putting a sticker themselves on the Sunglasses and upping the price .

   Is there any way to tell how much protection sunglasses give ?

30 Baht-3000 Baht for two products that look identical .

Peter showed me this demonstration a few years ago when buying sunglasses from a street vendor.

 

You might want to check www.zenni.com  for some great online options.  I have a couple of friends who are very satisfied customers of the company.

 

 

Good luck

you don't necessarily require polarized.  what is important is UV protection.

Good comparison of polarized/non-polarized here

How can you tell whether they have UV protection ?

The little sticker stuck on them, saying so, doesnt give much of a gaurantee

[starky]

Even a lot of the cheap knock offs are properly polarized. It's not an expensive process the extra 3000 baht comes from having ray ban, Oakley or gucci on the label. Cheap sunnies are not necessarily shit sunnies contrary to what manufacturers would have you believe.  Look at any sunnies used in industry these days they all have to pass standard for not only uv but impact protection but most of them cost well under 50 dollars.

when in doubt google it,

Also had a pair checked at a local optician once who confirmed they were UV400 rated

Most any name brand from a reputable shop should provide UV protection.

Any prescription lenses will as well.

I did google it and got the same result "buy a U.V. torch" , I just wondered whether there was a way of doing so, without buying a U.V. torch

Pretty much written on the tag of every pair of decent sunnies you buy uv rating on the tag polarised written on the lens. I suggest if you are that untrustworthy not to purchase your sunnies in thailand.

I think the last sentence of my post clearly states how to do that.  As starky also pointed out, at some point you might have to believe what is written on the label of your 150 baht investment, unless you want to lose alot of sleep over it.  If in doubt, check them following my advice.

I do feel that its a bit of a cheek, buy sunglasses from one shop and then going into another more expensive place to get them tested for UV protection .

  No need to mention "150 baht" , that is being rather derogatory , I was happy to spend whatever is needed to get a decent pair , I just didnt want to spend extra money for a label

You seem overly sensitive and worried.  The shop I went to was happy to do it, so as to compare it to their high-end products.  Not cheek, is common sense.  If it bothers you that much, go buy the light.

Can find a decent pair of UV400 glasses for 150 baht and polarized in the 350 baht range, so do not get your point.  Anyhow, I have done enough free educating for you, but I suspect that starky's comments are spot on.

Will you stop putting labels on me ?

I am not "overly sensitive " or " worried" , and I do feel that its taking a liberty , buying goods from one shop and then going into another shop to check authenticity  .

   You also didnt "educate me" , I asked how to check for U.V. and you gave a link to check for polarisation .Which are two different things .

   Yes, I knew that I can go to an optician to get them checked , but I wanted to know whether there was a way of finding out BEFORE I bought them .

   You didnt know the answer , so dont try to come across as a Mr know it all

Slight correction.  Instead of  " You seem overly sensitive and worried. ", I should have written "you ARE  overly sensitive and worried."

I taught you how to use google and also where to get your 150 baht glasses checked.  People price check things online everyday while doing bricks and mortar shopping so your "taking a liberty"  luddite comment is out of touch with current practice and reality.  Get with the times, buy yourself a gadget and get into the rhythm of modern life.  Google things you do not know.   The rest is up to you, bearing in mind starky's words of wisdom.

Shops are businesses and business's are there to make a profit .

You may feel comfortable , buying cheaper goods and then taking those to a more expensive shop to get them checked for authenticity . I would happily go in there , if they provided a paid for service , but I feel uncomfortable being a free loader , its the same as buying a beer form 7/11 and taking it to a bar and drinking it in the bar without buying anything from the bar .

   You may not feel uncomfortable doing that , BUT , I do .

The price wasnt my main concern , as after research on line (BEFORE you kindly told me how to use google)I found out that cost doesnt always mean quality , some of the more expensive sunglasses offer less protection than the more cheaper ones and I didnt want to buy expensive glasses , that were just 30 Baht market ones with a sticker on them .

Also a UV torch is no help when buying glasses that are suspected not to offer the claimed UV protection.  Will the vendor provide you with a darkroom in which to test his dodgy glasses?

Do other countries not have issues with false claims of sunglasses' UV protection, then?

[scubascuba3]

Without a UV torch you just need to buy a known make from a reputable company. Ideally buy abroad. Do some background reading on the sunglasses you like which will include the UV protection

Sure they do.  Ok.  Worldwide, when purchasing sunglasses tend not to buy cheap knock offs or from unreliable distributors as there will be no guarantee of their quality.

[rak sa_ngop]

Stop bickering!!!

 

You can but a cheap small UV torch for about 100 baht. (I bought 10 in Chinatown for about 250 baht total).

 

Most only have white light and red IR light, so make sure you get the ones that also incorporate UV (purplish light).

 

The UV glasses I tested reduce the UV light by about half but not completely, although this is for the torch generated frequency light, so maybe more effective at other frequencies.

Assuming you plan to wear them a lot, frame quality is important as well.

Beyond UV, the general optical quality of the lenses is important as well.

I wear prescription Ray-Bans, but I would not be afraid of eye damage wearing most any name brand purchased from a reputable shop.

That's a good point re. the frames, although I sense that the OP is liable to want verification by a structural or industrial engineer re. safety, durability etc. An ergonomic specialist may also be required. In addition to the UV torch he will carry everywhere with him, he may also need to bring a hammer to bash the frames to check basic structural integrity (along with certified 3rd party structural verification).  However, he may not be very popular at the cheap charlie sunglass stands!

Slow clap...the suspense was killing us!

[sanemax]

I did actually buy two pairs of sunglasses .

They also had a pair on sale for 29 Baht and the shop assistant claimed that they were also UV resistant .

   I didnt think that they would be that cheap , so he was either lying or the shop had put the wrong price tag on them .

  29 Baht , cant really go wrong

I'm not being argumentative, I'm commenting on what you said which seemed to suggest that worldwide people tend not to buy knock-offs or buy from unreliable sources.  That is clearly untrue.  Here's your quote...

For clarity and to clear the air you said " do other countries not have issues" to which I replied sure they do. I then amended my post by saying worldwide if you are going to buy glasses try to not buy knockoffs or from irreputable suppliers. So I was agreeing with you and saying no matter where in the world you are don't buy shitty sunglasses. Sorry if it didn't read that way.

I understand what you are saying now but that is not what you said originally.  I copied and pasted what you said originally!

 

You did not amend that post after posting it, if you had amended it the post would show as having been edited!
