Boaters and fishermen have used polarized sunglasses a long time to reduce glare from the lake. However, polarized sunglasses can offer benefits and advantages when worn for most outdoor sports activities. The popularity of polarized lenses has increased dramatically as has availability. In the past few years, however, the benefits of polarized sunglasses have been realized by a variety of other outdoor sports enthusiasts as well as by drivers and general use wearers.
How Do Polarized Sunglasses Work?
Light reflected from surfaces like a flat road or smooth water is generally horizontally polarized. This horizontally polarized light is blocked by the vertically oriented polarizers in the lenses.
The result: a reduction in annoying and sometimes dangerous glare.
Polarized sunglasses have five primary advantages:
They reduce light transmission by only allowing light to transmit through select angles.
They reduce UV light and reflected glare off surfaces such as snow, water and pavement by blocking light at certain angles.
They increase contrast sensitivity allowing more distinction between under water objects and during sport activities.
Boaters and fishermen have used polarized sunglasses a long time to reduce glare from the lake.
They reduce sunlight glare for driving, especially on the hot sunny days of the summer when the heat is rising off the road causing increased polarity.
By making an analogy to Venetian blinds we can describe the principle of polarized sunglasses. The blind allows light to be transmitted through select angles while blocking light at certain angles. For enhanced clarity and reduced back glare, some polarized sunglasses have an Anti-Reflective coating on either the front or back of the lens.
Consequently, liquid crystal displays (LCD) may cause polarized sunglasses to react adversely by making the LCD’s invisible when viewed at a certain angle. This type of LCD displays can be found on bank ATM machines, dashboards of some cars, and some cell phones.
The jury is still out on the effects of polarized sunglasses on snow-covered surfaces. Some experts say they can reduce the intense glare that is caused by sunlight reflecting off snow. Others state polarized sunglasses are not very feasible for sports such as downhill skiing because they may not provide the contrast the eye needs to distinguish changes in snow conditions.
However, for most other sports and activities, polarized sunglasses can offer great advantages. And today, many types of polarized sunglasses are available on the market. Whether you spend your time boating or waterskiing, in-line skating or mountain biking, driving or jogging, polarized sunglasses are an excellent choice.
While I can’t vouch for the truthfulness of this story, I’m relating it here as told by my nephew Jonathan. He insists to this day it really happened.
It was June of 2002. The preceding month had been very rough on Jonathan. He had gone through more pain than he thought he could handle. His parents had recently divorced, and his older brother had run away, leaving him completely alone. It was hard to deal with the changes. He felt as if there was an emptiness, avoid that could not be filled the matter what he tried to do. In his despair, he opened up the last gift that his father gave him before moving out of the house. It was a late birthday gift. It was a brand-new outdoor watch, actually one of the best outdoor watches to be bought at the time.
Even though Jonathan had never been in the woods before, he felt he needed to go. Into small town, trees were just a five minute walk away. Before all of this, he seldom spent very much time outside of his room, always playing video games. However, the memories in that house were just too much. He needed to get away. Grabbing his backpack, tossing in water bottles and a couple sandwiches, he decided to make a day of this walk in the woods. He didn’t know when he was coming back, only that he needed to go, and for some reason he felt something or someone was waiting.
A few miles into the forest he heard what sounded like an owl, but he couldn’t see any birds in the distance. It was late afternoon, and the sun was slowly setting through the trees. There was little snow on the ground, despite being just a few weeks into January. He knew he only had a little bit of light left and needed to head back. The hoot of the owl was distinct this time, calling at him, beckoning him to follow. Despite his best intentions, and race against the receding daylight, he headed deeper into the woods.
Several minutes in, he found a cave, embedded in the side of the mountain. For some reason, there was a fire inside. Around the fire were people, and they turned to look at him, with nothing but kindness in their eyes. Looking at his outdoor watch, he knew his time is short, and he gave a nod and a shy wave. It was then that one of the girls stood up from the fire, walked toward him, and stood just a few feet away. She said, “They love you. Always remember that.” and then walked into the woods. He looked back into the cave, but now there was nothing there. Turning quickly, he could not find the little girl who had just spoken to him moments before. Another hoot of an owl called in the direction of his home, and he headed back as fast as he could. Jonathan never forgot that day, and even though it was probably not real, it was exactly what he needed to hear. It was an illusion that would stay with him the rest of his life. Although the outdoor watch probably had nothing to do with this adventure, whenever he wears this watch that his father gave him, he remembers that even in the darkest of times, there are always people that love you.
I was about 5 years old, and we were visiting friends in New Jersey. They had a very cool in ground swimming pool, and that all-important rope between the deep end and the kiddie side of the pool was missing. I couldn’t swim, but I really wanted to go into the pool so my mom let me, putting me on the “honor system” to watch for the line at the bottom of the pool or the two rope hooks at the edge of the pool to be sure I didn’t venture into the deep end. Really, what kind of mother puts a five year old on the honor system? This was destined for disaster and you already know what happened, I teetered too close to that line, and went over, sinking like a cute little stone.
When we returned home, my mom immediately signed me up for swimming lessons at a local diving school with a big indoor pool. You know what they do to little kids on the first day of swim lessons at a diving school? Yep, they line the kids up and shove them into the deep end of the pool!
Here’s what I learned in all of this; when you’re actually drowning, you don’t know how to get back to the surface, and you panic because your lungs have filled up with water. In the first pool, I was panicking because I was really drowning, luckily someone spotted me in time and came to my rescue. In the second pool, I still sank like a cute little stone, but I didn’t panic because I figured one of the 8 or 9 adults standing around would probably not let me die. Indeed, I got some help getting my head above water, and started learning what to do almost immediately.
What does any of this have to do with the state of broadcasting? Simple, the first scenario isn’t going to happen, broadcasting doesn’t employ enough people or sub-contractors to warrant any kind of a bail out. Nobody is going to pull us out of the deep end of the pool. We’re stuck on the bottom, and we can either panic and flail wildly about, or start trying to think our way out of this.
Panic equates to cutting expenses wildly, laying off massive amounts of employees, and treating every nickel that comes through the front door as if it were the second coming of whatever it is you believe wasn’t done with us the first time around. Problem is; we’re not a manufacturer of autos or anything else for that matter. It’s easy to make “less cars”, just make 50 this week instead of 100. Not so easy to make “less radio” or “less TV”. As far as lay-offs go, hate to say it, but in most instances we’re letting go of loyal people who were working hard for less-than-staggering amounts of money. When they’re gone, they will probably find another industry or employer who pays them better and is a bit less… shall we say, fickle? Bottom line is, when we need some people back (and we will), we’ll either have to pay more to get them, or lower our standards. Yes, I’m sure you’re just as shocked as I at the possibility of a broadcaster lowering their standards! Now, about those nickels coming through the door; do you really think that once we’ve provided our unique and invaluable services to dozens, if not hundreds of clients for reduced rates, that we’ll EVER be able bring those rates back up again? No matter what some sales guru has tried to teach you, we are not a necessity for anyone. People will pay whatever the oil companies tell them to for gas, they’ll buy electricity without ever truly understanding all that gobbledygook on their bills, they just write the check and move on. But if a media outlet tells you that what you bought last week for $20 is now going to cost $60, first comes the inevitable, uncontrollable laughter. Then, once you settle them down, you have to try and explain on what planet someone would pay for an increase like that.
So here we are, still denying our new reality. This is the way things are, and probably will be for longer than any of us would like. How do we get through these difficult times? What? You really thought I had the answer? You’re reading this and thinking “He’s the Broadcaster of the Year, he MUST have the answer”. First up, if I did have the answer, I’d be Broadcaster of the Freakin’ Century. Second, nobody is going to give you an answer, a magic formula, or any other panacea. The best we can do is to do what we do best… make good radio or TV. Find the efficiencies where we can and when we can. The days of cruising through a work day are over for everyone, if somebody’s not busy, you either don’t need the position or that’s the wrong person for the gig. Cut the expenses where you can, but once you reach bone… stop! We still need to transmit a viable product, without that, all is lost. None of this is going to be easy, and it’s not going to happen this year (I don’t care what anybody says)… We need to learn to live within this new reality, get our heads above water and realize that it’s the best we’re going to do for a while… until we learn to swim all over again.
