Now, turn your eyeglasses into sunglasses at your command

Now, turn your eyeglasses into sunglasses at your command

Washington: If you are fed up of carrying spectacles and sunglasses separately, or are annoyed at your transitional lenses glasses, which change with light, here's some good news!

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.

In the study, led by Anna Osterholm in John Reynolds' group at the Georgia Institute of Technology, the researchers point out that most transitional lenses now in 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 colour 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 have now 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 colour 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 findings are reported in the journal ACS Applied Materials and Interfaces
