Video: Different Types of Lenses for Sunglasses

I stumbled across this video the other day, and I’ve decided to share it with you because it is very well done.  The video demonstrates the various types of lenses available for sunglasses (Matrix sunglasses as well as – gasp – other types…).  Although I have written about this topic several times in the past, I think the video offers an added dimension because it allows you to visually see the different types.  Thus, what follows is a brief summary of the key points of the video, or if you’d prefer, you can watch it right now immediately below.

The video starts out by describing the various tints available.  The first type shown is solid tint, which can be applied to just about every type of lens.  Solid tinted lenses, as the name implies, offers an evenly-distributed tint throughout the entire lens. Many people prefer solid tinted lenses because they are inexpensive yet effective.  The next type of lens shown is the gradient tinted lens.  Unlike solid tinting, gradient tinting is not evenly distributed across the lens.  Instead, these lenses are generally darker at the top and gradually get lighter toward the bottom.

The next type of sunglasses shown is those with photochromic lenses, which are sometimes known as transitional lenses.  They are clear when worn at night or within dimly-lit environments, but they darken up in bright sunshine.  This darkening is generally triggered by the UV rays of the sun.  The main downside of transitional lenses is that they are not effective while driving, as the vehicle’s windshield usually blocks most of the UV rays that otherwise would have triggered the darkening effect.  Another downside is that these lenses do not get as dark as regularly tinted lenses, and thus they may not work for people that are extremely sensitive to bright light.

The next type shown is polarized lenses.  This type of lens helps diffuse reflective light that bounces off of horizontal surfaces, and as such they are preferred by skiers, drivers, surfers, and fishermen, to name a few. The only real downside of this type – aside from the fact that they tend to be more expensive – is that the polarization can sometimes interfere with a driver’s ability to view dashboard LCD displays.

The final type discussed is “Drivewear” lenses, which as you might expect are specifically designed to be used while driving.  These lenses combine the benefits of polarization with photochromic lenses for maximum visual acuity while driving.  The lenses actually change color depending on the driving conditions.  For example, they turn green when it’s overcast, medium brown in bright conditions, and extra dark when in bright sunshine but NOT in the car.

So, I hope you enjoyed this quick tutorial on the various types of sunglass lenses available.  The bottom line is that no matter what your hobby or lifestyle, there is certain to be a style of sunglasses that will match your needs perfectly.
