Polarized vs non polarized glasses:
Today we’re talking all about polarized vs non polarized sunglasses now myself i’m a huge sunglasses collector and fan and i’ll tell you something polarization makes a huge difference when it comes to sunglasses if you’ve never heard of polarization before or just wondered what in the world they’re talking about when they mean polarized we’re talking about how sunlight or light coming from any external source comes down and hits an object and then reflects off of it when that light comes down from something like the sun it is coming in every single direction it’s coming from a horizontal direction and up and down vertical direction every possible angle that you can possibly have so when light comes in crashes into an object specifically an object with a flat horizontal surface.
Such as the road a car windshield maybe a large body of water such as a lake a river or an ocean then the light that radiates from those objects doesn’t scatter in all directions it’s going to bounce off in a flat horizontal way and we call that polarized light and if you have some sort of a technology such as a polarized filter that selectively neutralizes that exact horizontal light then you can eliminate it and you won’t see that whole reflection it’s pretty wicked and just to help show you guys what polarization really can do for your vision and your visual experience through a pair of sunglasses.
I grabbed a couple of my sunglasses ones with polarization some without polarization and i took them out to the road and onto the water so i could show you what it really looks like so hopefully with those little video clips there you’re able to see the difference of with and without that polarized filter and one thing that’s kind of cool is that polarized filters they are oriented a certain direction to neutralize that horizontal reflecting light but that means that you can rotate a polarized filter and change the amount of light passing through it so for example if you’re wearing sunglasses and you tilt your head to the side you are changing the orientation of that polarized filter and then you can really see the big difference.
So if you have ever if you ever see me walking on the side of the road you’ll probably see me just being nerdy enough where i tilt my head side to side to side all the time that’s not just because i like to bob my head in different angles it’s because usually i’m wearing polarized sunglasses and i just find it entertaining to watch the different reflections of light coming off of a surface now maybe you’re wondering hey do i really need polarized sunglasses i don’t think anybody absolutely needs polarized sunglasses but if you are somebody who’s very light sensitive or you’re just very big into sunglasses and seeing your best maybe you’re somebody with migraines and you have difficulties with these bright reflections coming off of objects then yes i think polarized sunglasses are probably the best choice for you.
If you’re somebody who also likes to drive a lot because the roads can get wet or you can see a lot of glare coming off of windshields and a wet road for example then yes polarized sunglasses are gonna also help you a ton because it’s gonna reduce all that extra glare now one scenario where having polarized sunglasses is an absolute must in my opinion is if you are looking for the best sunglasses for fishing and that is because when you’re on a large body of water and you’re fishing you’re looking down directly into that water it’s usually at just the perfect angle to see a lot of reflections of the sky or something above you and so if you have polarized filters on you can eliminate that glare and see directly into the water and you can even see fish and different weeds and rocks everything and to simulate that effect.
I even filled a large bowl of water and put my watch in there just in case i had an idea if you were maybe out on just a low shallow river and you dropped your watch or something in it and you couldn’t quite see where it was sunglasses with a polarized filter in them if you rotate them the right way. if you didn’t have the polarized filter on there you just see a huge reflection of the sky so yes if you are into fishing at all even in just a little bit you’re going on a big fishing trip or something like that definitely pick up a pair of polarized sunglasses yes polarized glasses are my personal favorite and i pretty much prefer to wear them all the time but there are some scenarios where you do not want them yes if you’re fishing you want to have them yes if you are somebody who’s driving a lot you’re on the road you see a lot of wet roads you can see light bouncing off that flat horizontal surface of asphalt maybe car windshields yes polarized lenses polarized sunglasses are ideal for those situations.
However if you are somebody such as an airline pilot if you’re in the air force maybe you are in the military or maybe you drive a ship or something and you’re looking at a lot of electronic dials then no a polarized pair of sunglasses is probably not ideal for you at least when you’re using those electronic dials and that’s because if you are in something like a cockpit your airline pilots their dials in front of them in the cockpit are no longer just mechanical dials that go back and forth they’re usually made with a computer screen and something that a lot of people don’t know is that computer screens have polarized filters in them and that’s exactly why if i hold up this polarized filter here for a camera and i rotate it just the right way you can no longer see through it that’s pretty wicked right.
So i can kind of go non-polarized polarized non-polarized polarized and that’s because the polarized filter of the camera filter here and the polarized filter in the computer screen are polarized against each other and you just can’t see through them at all and that’s why if you ever wear polarized sunglasses and you pull up to like a gas station and you look at the electronic dial that tells you how much fuel you’re pumping into your car you might not be able to see it and that’s because the polarized filters in different kind of computers and electronic screens can negate each other and you can’t really see it sometimes you can see this in car radios sometimes on older phone screens it kind of does depend on a few things now a good question.
I’ve gotten from patients and viewers is is there a difference of polarization from one company to the next in terms of different brands of sunglasses and honestly i don’t know i’ve looked into it and i’m not really sure if there’s a difference in technology of one polarized filter versus another certainly there’s a difference in quality of glass or plastic of how your sunglasses are made or what type of brand made the filter for your camera polarized filter but in terms of the how the polarization is made.
i don’t think that makes a difference but i do pass that off to you if you know a little bit more about how polarized filters are made and if there is really a difference of polarization effect of one company brand versus another i want to know because i just nerdy like that i like to know those things but thankfully polarization technology is available in sunglasses and honestly i think it’s pretty cool if you haven’t tried them recommend it.
