How Polarized Lenses Work

Polarized Lenses FAQ's Courtesy Of Pyramex Safety


What is glare or polarization?

Light has many interesting properties, especially when reflected from another surface. Normally, a light source produces waves which go in all directions. When light is bounced from a surface like glass, water or snow, the light waves polarize, meaning that they orient along an axis. Another explanation is that polarized light waves travel from “pole” to “pole” along an axis.

Why eliminate glare?

Glare distorts the true color of objects and makes them harder to distinguish. It also causes a mirror-effect on wet surfaces so that objects below the water’s surface cannot be clearly distinguished. Glare can be uncomfortable causing eye fatigue from squinting.

What does a polarized lens do?

As light travels from its source, its waves are not restricted to one direction. Light from a single source can travel in the vertical plane, the horizontal plane and in any plane in between – all at the same time. However, upon passing through the polarizing filter, light is only allowed to pass through in one plane. The remaining light, manifested as glare, is absorbed by the filter.

Some people prefer to think of the polarization process as a Venetian blind process. To think of polarization in this way, think of the polarizing film as a Venetian blind oriented so that the vertical light rays (glare) are blocked. Another way to look at the Venetian blind process is these blinds block light that strikes them from certain angles, while allowing light from other angles to pass through.


How do you make a lens polarized?

There are two ways to produce polarized lenses. Both methods use a polarizing film to block or change the angle of glare so that it is not visible. One way to polarize lenses is to mold the film into the lens. This is done by suspending the thin polarizing sheet between two molds. Optical quality plastics are then poured around the film. As the plastic hardens around the film, it creates a solid material rather than a layered one. Another method is to apply the polarizing film to front surface of the lens and cover it with a scratch resistant coating. This method allows polarization for the thinnest lenses possible.


A review of "Content Rules: How To Create Killer Blogs, Webinars, etc."

It’s ironic. As I sit here with my laptop, I’m struggling to compose a review about a book that helps you create content that people will want to read - “Content Rules - How To Create Killer Blogs, Poscasets, Webinars, etc.”

My struggle originates from making sure this review and this book are relevant to you; whether you’re a salesperson, a branch manager, a business owner, or a VP of operations. 

The answer is, “Yes, this book is relevant because we’re all writers now.” We write tweets. We write Power Point presentations. We compose webinars.

But, do you wonder why more people arent’ “liking” your company’s Facebook posts or why they don't marvel at your YouTube video that you spent so much time and company money on? Then, “Content Rules” can assist you to dig deep into your printed and social media content and help create material that people want to read and pass on. 

For example, River Pools and Spas sold more fiberglass pools than any other company in the USA. The owner used to see his his company as a “pool company” but he was wrong. He now sees his company as a content marketing company giving more valuable, helpful, and remarkable content to consumers than anyone else in his field.

Here's the money line from Chapter 4 regarding Hubspot, which sells "inbound" marketing software;

"interuptive outbound marketing methods (trade shows, email campaigns to purchased email lists, telemarketing, and advertising) are old school. What works...is inbound marketing that attracts customers to you (and includes producing killer content, by the way).

So, without giving away the plot of the book, here's a synopsis of their eleven rules from Chapter Two of "Content Rules":


  1. Embrace being a publisher: If you need convincing, read chapter 1 fo the book. 
  2. Insight inspires orginality: Know yourself better than anyone and know your customers. What keeps them up at night? Write about what your customers care about. 
  3. Build Momentum: Why are you creating? "I want my customers to be educated about fall protection." OK, what do your customers need to know about fall protection? Can you narrow that topic? Your objective creates good content. 
  4. Speak human: Use the language of your customer. Speak in conversational tone, with personality and true emotion. Please, please, please, kill the corporate speak!
  5. Reimagine; don't recycle: good content is reimagined at its inception to be used later in various platforms such as Power Point slides, YouTube, Twitter, etc. We've written tweets based on newsletter articles and blogs, such as this one!
  6. Share or solve; don't shill: create value for your customer in your communication, don't sell. This positions you as reliable and a valued source of information. Help your customers solve a problem, do their job better, make them smarter, wittier, cooler. 
  7. Show; don't just tell: Good content doesn't preach or hard-sell. It shows how your product lives in the real world. Use case studies. ZOLL, one of our principals, is a master of case studies regarding users of their AEDs. 
  8. Do something unexpected: Especially, this applies to business-to-business (B2B). B2B can be, how shall we put it, b-o-r-i-n-g! So, do something your customers wouldn't expect. 
  9. Stoke the campfire: good content sparks interaction between you and your customer and among your customers themselves. 
  10. Create wings and roots: ground your content in your unique perspective and point of view but give it wings to soar freely and be shared across social platforms.
  11. Play to your strengths: you don't have to publish everywhere and create everything. But, you do have to do some things - and, at the very least, one thing - really, really well. We've focused on this blog, a paper newsletter, and a Twitter account. We'll publish across more platforms in the future but we're focusing on these few methods first. 

I suggest downloading the e-book instead of buying a printed copy. The e-book version has links to cited examples such as web sites, slide presentations, etc. Those examples helped us to see clearly what the authors were referring to.

Why the "Laws of Subtraction" apply to your business

"To attain knowledge, add things every day. To attain wisdom, subtract things every day." Lao Tzu

After several years in selling, we discovered that the less we say during a product presentation, the surer the sale will happen. Why? Because limiting information engages the imagination as clarified in Rule #3 from “The Laws of Subtraction” by Matthew May. Why say more when you can say less? “Subtraction can mean the difference between a highly persuasive presentation and a long, convoluted, and confusing one. Why say more when you can less?”

“The Laws of Subtraction” contains six laws and anecdotes to support those laws. For example, Law #1 states, “What isn’t there often trumps what is there.” Consider the iPhone 5S. Like their competitors, Apple could have added more wiz-bang features but chose not to. Their focus was keeping the essential and make what was there - finger print ID, IOS, etc - the best in the business. 

Law #2: “The simplest rules contain the most effective experience.”

For managers, you’ll love Law #4: “Creativity Thrives Under Intelligent Constraints”. Quoted author Teresa Amabile says, “Here’s the key to the conundrum for managers who want to stoke the innovation fire: That close cousin of scarcity, constraint, can indeed foster creativity.” You give deadlines for projects, don’t you? This chapter details why deadlines do work. Visit ted.com for some of the most engaging and thrilling talks that you'll ever experience. A paying audience can hear the most creative people on the planet talk about their work in 18-minute (or less) presentations. The boundry of the 18 minute talk is its ability to provide a focus and a framework, which is exactly what the human brain needs. 

Law # 5: Break is the important part of breakthrough. Although the story is too long to transcribe here, the author chronicles the success of Wellness Mart, MD. This refreshing medical-care concept is a cash-based retail doctor's office that serves only healthy people, not sick people. Read their take on health insurance and your eyes will be opened to one solution to the health care "crisis" in the US.

Law #6: Doing something isn't always better than doing nothing. Doing nothing is impossible but when we say we are doing nothing what we really mean is we're taking a break from our normal business in some way. And that is when our brains are the most creative, according to author May. Author J.K. Rowling developed the outline for her "Harry Potter" series while stuck on a crowded train. All of the famous insights, from developing the Theory of Relativity to the idea of Post-It notes, came at strange times and places; in a streetcar, on a train, while driving a car. They involved a change of scene and time away from the problem-solving activity.

We recommend reading and studying "The Laws of Subtraction" by Matthew May if only to drive home the book's main point; When you remove just the right things in just the right way, something very good happens.
