How much do you really know about Polarized sunglasses? Which color lens is suitable for baseball and which color would be better for sailors or mountain climbers?There are essentially six different color polarized lenses available, and each has its own unique features and applications. You need to know those differences to know exactly what you should be offering  your clients.


Why This Matters to Your Clients (And Your Business)

The knowledge and skill of the distributor, optician or even the salesman can ensure that a client can maximize their experience for any lighting conditions. If you’re knowledgeable about what you’re selling or what you could be selling, you’ll be in a position to grow your business.

In this blog, we’ll explain (in detail) the difference between the polarized lens colors and their applications to get you as informed as possible about polarized lenses. We’ll look at polarized lens colors to help you either choose or recommend the best-polarized sunglass lenses for a specific need.

Which Customers?

Whether your customers are professional athletes actively competing or use sunglasses for driving, you need to take into account the varying conditions that can affect their performance and sight. To do this, you need to know everything about Polarized lenses to be as informative and valuable to your clients as possible. Consider the lighting conditions: Mountain bikers and trail runners are likely in and out of trees on a partly cloudy day. Professional fisherman not only wear glasses for protection, but the correct polarized lens selection affords the fisherman visibility into the water to spot potential catches, but what about on a cloudy day?

How do these conditions affect their visibility, and which lenses will be the best for their particular scenario?

Proper lens selection can be critical when making important decisions in these types of situations; even the size of the lens and shape for wind protection. With all of the different lens colors available, how are you (or your clients) supposed to make the most informed decision about which polarized lenses to use?

 

Benefits of Polarized Lenses

 

There are two main factors at work with polarized lenses

  1. The polarized filters eliminate obstructive and blinding glares of light, for a clear and uncompromised vision.
  2. The color of the filter reduces light transmission while selectively absorbing colors, which means you still see color. That lets the lenses enhance or soften the effects of particular colors to the wearer, which is often why the sky would look “bluer” or “redder” while wearing your polarized sunglasses.

Why is this useful?

Take baseball as an example - by selectively filtering particular “waves” of light, the human eye can distinguish with more accuracy the perceived outlines and sharpened edges of say a baseball, which is useful when it happens to be moving at 90 miles per hour.

 

Aren’t Polarized lenses all the same?

The color differentiation is what makes all the difference. Different colored polarized lenses cater for different lighting conditions and situations where edge variations and contrast are important to the wearer, like ball sports or driving on the freeway.

If your clients take the time to make a proper color selection for their application (with your excellent advice), it will provide them with optimum vision and comfort in any bright environment. So, particular care must be taken when selecting a lens color, as certain lens colors might be detrimental to the wearer in some cases.

Lens colors can alter the wearer's’ view of their environment, and it is important to demonstrate how by providing different options and samples. This is where a thorough understanding of various lens tints and colors will enable you to make the best recommendations for each case.

 

1. Brown Lenses

Brown is one of the most common color tints used with Plano sunglasses, and you will see them in all the eyewear dispensaries selling polarized sunglasses. Brown lenses are best used in bright sunshine days or lightly cloudy weather conditions, and provide excellent acuity in partially cloudy weather due to the lenses’ ability to increase the overall contrast.

Polarized brown lenses are designed to block blue wavelengths of light from approximately 400 to 500 nm. You can read more about what wavelength goes with what color in this article from NASA.

By blocking these specific wavelengths, the blues, and blue-violet, brown lenses provide wearers with high-contrast and color enhancement, maximizing detail from green wavelengths. This applies in particular against blue and green backgrounds, such as sky and, making these lenses ideal for active hikers or anyone looking for a comfortable all purpose lens.

Recommendations?

Recommend brown polarized lenses for running, baseball, cycling, water sports or simply for casual wear. Many fishermen prefer this color lens to help spot fish swimming in shallower waters but aren’t as effective for deep sea fishing where the water tends to be much darker.

 

2. Gray Lenses

Also one of the most commonly found polarized lens tints use with sunglasses, gray is an all-round neutral lens. Gray lenses are best for bright, sunny days from early morning until sunset. These lenses aren’t really the best-suited choice for overcast days with minimal sunlight; the deep density and darkness of the lenses can be too dark for the wearer and reduce overall visibility in these specific situations.

Gray colored lenses filter all wavelengths of visual light evenly across the color spectrum. Through reducing the light intensity, gray lenses will keep the colors true for the wearer, and enhance depth perception and reduce eye fatigue in bright light conditions.

Recommendations

Grey polarized lenses are recommended for: baseball skiing, cycling, running, deep-sea fishing, beach sports, and sailing. These lenses are highly recommended for those spending a lot of time on or near the water. These are an excellent choice for the clients looking for only one pair of sunglasses.

3. Gray-green Lenses

Bausch and Lomb pioneered the gray-green lenses. These color lenses are the go-to choice for many pilots as you can still clearly see the electronic gyros and instruments used to navigate an airplane, which isn’t possible with some of the polarized lenses.

The combination of the deep green lens with the deeper density of gray offers superior protection in bright sunshine environments. These colors allow for increased contrast from the lower wavelengths and protection from the colors to which the human eye is most sensitive.

Recommendations

With excellent enhancement capabilities of the gray-green lens, these polarized lenses are recommended for pilots and almost any sport or simply as a casual lens color.

4. Orange and Yellow Lenses

The density/darkness of a polarized lens is directly related to its polarizing efficiency, i.e., the lighter the lens, the less it polarizes. This might seem like an obvious conclusion to draw, but you have to consider the trade-off between the advantages of polarized lenses and the effects of the lens’ colors when thinking about lens colors such as orange, rose, yellow, and light green. Some light-colored polarized lenses polarize as little as 20 percent.

 

  • Orange lenses: This lens color offer high-contrast for intermittent light conditions, improved depth perception in overcast conditions. A light transmission of 70 percent plus provides enough protection in most cases except for very bright sunshine. Orange lenses block blue wavelengths of light which have the tendency to make objects appear hazy. These lenses are recommended for sports shooters i.e. skeet shooting and for skiers in low-light conditions, especially early mornings and evenings.
  • Yellow lenses: These lenses are often referred to as “blue-blockers,” and greatly increase the contrast and depth of vision. Yellow lens tints have the ability to filter out “hazy” light that is hard on the eyes that can make the environment appear brighter. These tints are typically favored above orange lenses.
  • Rose lenses: This color sharpens focus and contrast in a variety of light conditions. Rose-colored lenses are particularly useful for patients who suffer from migraines. Research has found that a specific rose tint (FL-41) can block out the light associated with triggering migraines.This is another favorite color among skiers, mountain bikers, trail runners and baseball players in varying light conditions. These lenses are excellent for activities where detail is important.

5. High-Alpine Gray Lenses

This color lens is quite niche; an especially dark gray lens for the use in high altitude environments. Standard tinted lenses increase visibility around the ice, which is especially useful for mountain climbers and skiers where extremely high levels of UV radiation are prevalent. It must be noted that according to ANSI Z80.3 standards these lenses are deemed unacceptable for driving in the USA, and thus special consideration should be used when recommending these lenses Stateside.

 

6. Photochromic & Variable Density Polarized Options

Photochromic lenses are optical lenses that darken on exposure to specific types of light of sufficient intensity, most commonly ultraviolet (UV) radiation.They are an excellent choice for those looking for a single set of sunglasses.

The two versions available today are:

  1. Varying of polarizing efficiency by UV exposure (photochromic)
  2. A fixed gradient of polarization from the top of lens to the bottom (variable density)

In the first instance - these lenses offer the advantage of a polarized sun tint while remaining virtually clear while inside, outside or even after dark. A great example would be anyone who frequently goes to football, cricket or baseball matches that are known to start in daytime and finish at night. If they had varying polarizing glasses, they would only have to take one pair of glasses to a game.  As the sun sets and the day turns to dusk and into the night, the lenses adapt to the varying light and turn from a polarized sun tint back into a clear lens without having to change glasses.

In the second instance - variable density lens is a polarized gradient lens that has a deep tint at the top and gradually lightens toward the bottom of the lenses. These lenses provide the advantages of a polarized lens as well as the aesthetic appeal some fashion fundies might desire from their sunglasses. Photochromic polarized lenses are available from specialty sunglass manufacturers only and are available in both prescription and nonprescription lenses.
