IMPORTANT

You will find category written on most sunglasses.
The value ranges from 1 to 5.
1 is the lightest and 5 the darkest.
3 is the most popular setting.
But if you want to wear them for night driving (esp Polarized) then get Cat 2.

TSK, if you've ever seen those greyish glasses they give you at certain 3D movies - those are polarized films (with each eye at 90* polarization to the other - hence the ability to see different projected frames with each eye).... but as i was saying, thats probably as light as they come.

The skypol lenses are good enough. Be wary where you have them fit, these are two lenses fused together and cannot normally be fit onto half rim frames.

If you have the same fit on half rims, the coating will peel off gradually. I am not sure if your optician told you this.

There are three colour options available on the same. Ask him to show you all three samples in material as the colour varies from the ones seen in the printed manual.

I am considering polarized glasses. A friend of mine mentioned that it might affect the visibility of traffic lights. Has anybody encountered this problem?

Skypol looks good, I need to get my power verified again and go for it. I currently use Airewear from Essilor and could not find DriveWear as someone suggested here on Essilore India website. Can someone get me more information about DriveWear from Essilor? I may go with that after I get my power verified.

What do you guys think aobut using this pair as a regular for working with cumputers and as all day lenses!!

Interesting question.

Basically the only way it would affect the visibility of traffic lights, is if they were also giving off polarized light (ie had some sort of polarized on them).

To the best of my knowledge, this is not the case, though it would be interesting to see if there was any difference, especially on the LED traffic lights.

PS - If your car has a LCD display (clock, speedometer etc) - the visibility of that might be affected (ie totally blacked out!)

just found that Xperio is another option. This is the one from Essilor. Someone mentioned about DriveWear earlier, its from Transitions.

Again, Xperio can be a primery outdoor pair for you and cannot be used as all-in-one, what I was looking for!! But it looks better than other tinted solutions, should definately be a better choice for Polarized experiance.

Completely agree with you. IT IS VERY VERY DANGEROUS TO USE ANY KING OF SUNGLASSES DURING THE DARK HOURS (even the highest quality polarized and the lightest tint) . PERIOD!

I have been using polarized glasses for several years, which I find very useful in day time, and in fog & rainy season too. But during night, believe me, they really do reduce the visibility -like having a dark sunfilm on your windshield. (A few years back, I actually did buy the lightest shade available - paid a few K for that - and tried it over many weeks before finally deciding not to use them in night. I have noted also the same effect in tunnels).

As already stated on this thread before, you can not have plain (i.e. non-tinted) polarized glasses.

I'm planning to get a pair of Essilor Xperio. Can someone please suggest me a decent frame for the same?
This is going to be a pair used for outdoors, I would like to go for some decent (standard or branded if its not going to make a big diff) frame which is light in weight. I love using my rayban aviator for outdoors currently. Is there a way I can get a good aviator frame for this pair of lenses I'm going to buy?

Given that we couldn't even see where the turning on the ghat section were, it did help us a lot. Anyone tried this?
.
in all probability it's because the sensor's are sensitive to IR, which our eyes are not. remember see-thru camcorders from sony's night vision?

since the the whole point of polarization is to cut light in some plane, it will look darker than plain glass, but you can get very bland color in the same.

yes, any LCD screen has a risk of getting blacked out at certain angles.

I use a 3$ clip-on polarizer on my regular glasses and it's awsome. I do it only while driving and i don't care if it looks weird. took probably two days to get used to it. it's very light. exactly like this but the shape of filter is more suited to my glasses.
