"Four Shades of Brown: Tuning of Electrochromic Polymer Blends Toward High-Contrast Eyewear"
ACS Applied Materials & Interfaces
Imagine eyeglasses that can go quickly from clear to shaded and back again when you want them to, rather than passively in response to changes in light. Scientists report a major step toward that goal, which could benefit pilots, security guards and others who need such control, in the journal ACS Applied Materials & Interfaces.
In the study, led by Anna Österholm in John Reynolds' group at the Georgia Institute of Technology, the researchers point out that most transitional lenses now on the market don’t meet many users’ needs. When wearers are driving or wearing a baseball cap, for example, the lenses stay clear rather than switching to a darker shade even in broad daylight. Also, the majority of available versions don’t block out the harshest light, such as bright light reflected off snow. And the change from colored to clear can take several minutes, which has safety implications for certain users including airline pilots. Reynolds’ team wanted to find a way to solve these issues.
The researchers designed a new kind of lens that can switch within seconds from clear to darkly shaded and back again in response to a small electrical charge that a wearer could control. They can also fine-tune the color of the lenses to match the full range of hues used in commercial sunglasses. To make the lenses, they say they used a method that could be easily scaled up for manufacturing.
The authors acknowledge funding from BASF.

This new invention will probably change the world of optics again .....
This new invention will probably change the world of optics again with photo chromatic lenses to become a historical fact in the near future.
Which major manufacturer will pick this one up and become the sole supplier for the length of the patents ?
While needing an electric current the source for it will have to have a battery hidden in the frame. Another challenge for frame manufacturers and battery companies.
This one looks one of the major changes over the last 40 years.
What do you say ????
How much time do you give them ?

These days it might just happen that another major manufacturer might jump the gun and get to it faster.
I can see some of these optical corporations having urgent meetings .............
If the electrochromatic theory is workable to a degree that it can be marketed to a large quantity of optical retailers ...............whoever they are.
The one that gets the patents can actually stop the use in various geographic and or competitive areas. The research right now is funded by BASF one of the largest chemical corporations which would be in control at this stage.
I can see some of these optical corporations having urgent meetings on this subject.
When the large corporations go for such a project they must see a future for it. ....

This time the project is supported by BASF, .................the present popular product was developed by PPG another large corporation.
