In part one of this three-part series, we took an in-depth look at standard light reactive lenses . In this second installment, we’ll be covering their extra reactive associates.
Answering the Call for Something Extra
Following the creation of standard photochromic lenses, a need eventually arose for a light-reactive lens that got darker outdoors and retained color in the car. Thus, extra reactive, light-reactive lenses were born.
In this installment of our series, we’ll take a deep dive into extra reactive photochromics to explore everything from technology to talking points in the dispensary. Either read through the article or click on one of the following buttons to jump to a section.
How Do Extra Reactive Photochromic Lenses Work?
This makes them a perfect fit for anyone looking to kick up the outdoor comfort and take the show on the road.
The question you’re likely asking is, “Why do extra reactives work in the car whereas other photochromics don’t?”
Standard light-reactive lenses activate solely in response to UV light. Most car windows are now treated to filter out UV for comfort and safety purposes. Therefore, UV light doesn’t reach the lenses in sufficient quantity to activate a standard photochromic to a noticeable tint.
Extra reactive lenses on the other hand, activate in response to both UV and natural visible light. This is why they’re able to retain their color inside the car. Even when the car windows filter out the UV light, the natural visible light entering the car keeps the lenses activated.
Outside the car, extra reactive photochromics achieve the darkest activated level of any light-reactive lens due to a unique combination of light-reactive dyes which respond to both UV and natural visible light.

What Are the Benefits of Extra Reactive Photochromic Lenses?
Extra reactive light-reactive lenses share benefits with standard photochromics and feature advantages all to themselves. Some of the key benefits include:
Who's the Ideal Patient for An Extra Reactive Photochromic Lens?
Due to the in-car activation and darker outdoor color, extra reactive photochromics are a natural fit for patients who spend time behind the wheel. And while that includes professional drivers, the benefits of these lenses extend well beyond that.

These are just a few examples. Your questionnaire results will undoubtedly give you clues to other lifestyle activities that lend themselves to an extra reactive lens.
Because these lenses respond to both UV and natural visible light, their benefits extend beyond environments with high UV levels. The following environments are prime for an extra reactive lens:

Setting Realistic Expectations Around Extra Reactive Photochromic Lenses
Setting realistic expectations about performance sets the stage for a better wearer experience. When it comes to extra reactive light-reactive lenses, here are a few points to consider:
Fade-Back Speed: Because extra reactive lenses get darker, they’ll naturally take a little longer to fade back. For quite some time, extra reactive choices were limited to one brand and patients were forced to wait up to 10 minutes to fade back. However, with the introduction of new technology, such as that used in SunSync Drive XT, fade-back times have been cut considerably.
Lens Material: Different lens materials can impact the overall performance characteristics of almost any light-reactive lens . SunSync Elite is one and only light-reactive lens that uses advanced technology to deliver consistent performance regardless of material choice.

Wrapping it Up
Extra reactive light-reactive lenses offer you a solution to one of the biggest pain points among photochromic patients – in-car activation. They also provide an extra dose of darkness outdoors, superior blue light defense, and 100% UV protection, making them a fit for everyone from professional drivers to moms on the go to outdoor enthusiasts.
