Shaded Lens Technology Heading Toward “On Demand”

If you wear prescription glasses, you may have tried transitional lenses. These specialty lenses change the tint of the lens in response to the intensity of light. However, there are limitations with these lenses:

• The transition time from clear to shaded (or vice versa) can take too long
• The shaded adaptation may not be effective in blocking out harsh lighting situations
• The lenses may not change in certain situations, such as when wearing a hat or driving

Scientists to the Rescue with New Lenses

Scientists, led by John Reynolds, Georgia Institute of Technology professor of chemistry & biochemistry and materials science & engineering, along with BASF, are currently developing an electrochromic polymer lens material that can change to and from clear-to-shaded in seconds. The change would be driven by a user-controlled electrical charge (like a switch) to allow for “on demand” changes. 

These revolutionary lenses may change the game for prescription eyeglass wearers – time will tell.

Even with advances in lens technology, the fact remains that wearing prescription lenses can be cumbersome and aggravating.
