SunSync Drive XT: One lens for indoors, outdoors, behind the wheel

By on

If you’ve ever worn light-reactive (a.k.a. photochromic) lenses, you’re undoubtedly familiar with the following scenario. You’re indoors and your lenses are nice and clear. You step outside to run an errand or go for a drive and your lenses darken up. Then you get inside your car and that comfortable tint starts fading away before your eyes.

Until now, this meant scrambling for your prescription sunglasses. Thankfully, the scramble for your suns is a thing of the past.

SunSync Drive XT is an extra-active light-reactive lens that gets darker outdoors and stays dark in the car. So, you enjoy comfortable, glare-free vision whether you’re in the park or on the highway.

Why do they stay dark in the car?

Why do extra-active, light-reactive lenses like SunSync Drive XT work in the car when traditional lenses don’t? Traditional light-reactive lenses activate and deactivate based on exposure to UV light. For good reason, most car windshields and windows come with UV protection built into them. No UV light getting into the car means no UV to activate your lenses.

SunSync Drive XT on the other hand activates based on exposure to UV and visible light. So, when you get into your car and the windows block the UV, the visible light coming through still activates your lenses.

The “extra” in extra-active.

In addition to working in the car, SunSync Drive XT also get darker outdoors. And not only do they get darker than standard photochromic lenses, they also offer you the darkest outdoor color of any extra-active lens available. They also change from dark to clear faster, and get clearer indoors than any other extra-active light-reactive lens.

Add all this to the standard benefits you enjoy with all SunSync Light-Reactive Lenses, and you get the ultimate lens package of comfort, clarity, convenience, and confidence:

  • 100% UV protection
  • Targeted blue light filtration
  • Exceptional scratch resistance
  • Outstanding cleanability

Take them for a 1-year test drive

As a VSP member, SunSync offers you an exclusive one-year, 100% satisfaction guarantee. This means you can try them out risk-free for a year. If you’re not satisfied, simply return them and they’ll be replaced with clear prescription lenses free of charge.

Ask your VSP network eye doctor about SunSync Drive XT.

  • Transitional lenses do not turn dark inside a vehicle because windshields already have protection in them

    • Angelina F. says:

      Hi Anna,
      Unlike most light-reactive lenses which darken based on UV exposure, SunSync Drive XT responds to both UV and visible light. So the lenses stay dark in the car, even if the windshield blocks the UV.

      • Crystal says:

        Wouldn’t that mean they will also darken when exposed to flouresent lights as visible light too & darken causing you to end up with dark glasses indoors?

        • Crystal says:

          Fluorescent*, sorry didn’t have my glasses on lol.

          • DB says:

            Agreed. I’m sure they are just adding more photochromic material. Problems I see are the same as yours, worse would be in colder weather where photochromic lenses work better. I would not use these lenses on a snowmobile on a low light conditions. It can be dangerous..

            It seems Angelina from VSP has only responded once…. hmmm…

        • Dave says:

          The only thing I’ve seen said is that they stay dark in the car. Nothing about them darkening inside a car. Maybe you still need the UV to start the process.

        • Angelina F. says:

          No, they turn clear inside. SunSync Drive XT activates with a combination of UV and visible light so your lenses would not activate solely from the visible light indoors.

          -Angelina F.,VSP

      • Kim B Staking says:

        Angela. How do these respond to bright headlights at night? Do they darken somewhat. My eyes are light sensitive, and headlights in the side mirror and lights from the front.

        • Angelina F. says:

          Hi Angela,
          These activate based on a combination of UV exposure and visible light, so they should stay clear while driving at night.
          -Angelina F., VSP

      • Lisa says:

        How do I find a Dr that carries them? I just have to call all the doctors in my area and see if they can get them for me?

        • Angelina F. says:

          These are available through VSP network doctor’s offices, you can find a location near you using the Find A Doctor Search on vsp.com.

      • Susan says:

        Angelina, how often does VSP update answers to the questions in “comments”?

  • Does this include bifocals????

    • Angelina F. says:

      Hi Carolyn,
      SunSync Drive XT lenses are not available in a lined bifocal, but are available in progressive lenses.
      -Angelina F., VSP

  • Liz Petzak says:

    Would these lenses darken while working on a bright (visible light) computer screen? My overall office lighting is dim, but my screen is fairly bright, by comparison, which is how I like to work. These lenses sound great, but wondering about this?

    • Angelina F. says:

      Hi Liz,
      That shouldn’t be an issue, Sunsync Drive XT is activated by a combination of UV and visible light so they should stay clear in an office setting.
      -Angelina F., VSP

  • Bill says:

    what is the level of darkness indoors? will they turn dark if working in the office by a window?

    • Angelina F. says:

      Hi Bill,

      Sunsync Drive XT lenses won’t activate from visible indoor lighting alone so in most indoor settings they would remain clear. If you are sitting by a window without UV filtration or tinting, the lenses would be more likely to activate slightly.

      -Angelina F.,VSP

  • Beth Geiger says:

    Do these lenses stay dark outside wearing a hat? I tried the older type photochromic lenses and found that not only did they not say dark in the car, but also did not stay dark if outdoors wearing hat or visor. Do these new ones stay dark outdoors while under a hat?

    • Angelina F. says:

      Hi Beth,
      Because these lenses are activated by both UV and visible light, they are much more likely to stay dark when wearing a hat than a traditional photochromic lens, but environmental factors could come into play that would affect activation. For example, if the brim of your hat is shading your glasses from the sun, and there’s not a great deal of visible or reflected light reaching the lenses, your glasses may not achieve full activation.
      -Angelina F., VSP

  • John says:

    Looks like these lens get darker outside. Will I still need to purchase a subscription pair of sunglasses, or will these lens be enough?

  • Debra Cherry says:

    I just got new glasses. Can I go back and have the SunSync Drive XT added?

    • Angelina F. says:

      Hi Debra,

      No, it’s not a coating that can be added after the fact, you would need to purchase new lenses. Sunsync Drive XT is embedded into the lenses that would be ground to fit your prescription. It is available in single vision and progressive lens styles.

      -Angelina F., VSP

  • Laurie Leclerc says:

    How much money does this cost?

    • Angelina F. says:

      Hi Laurie,
      The cost of the lenses will depend on your insurance coverage and your eye doctor.
      -Angelina F., VSP

  • Steve says:

    If they get dark based on visible light, then won’t they get dark indoors from the visible light that is indoors? That’s not something I would want.

    • Angelina F. says:

      Hi Steve,
      These lenses are activated from a combination of UV and visible light so they will turn clear indoors.
      -Angelina F., VSP

  • KATHLEEN GONZALEZ says:

    What is the average cost of these lenses? Is this something that can be added to the clear lenses I already have?

    • Angelina F. says:

      Hi Kathleen,
      Since this isn’t a lens coating they cannot be added to a pair of lenses you already have. The cost will depend on your vision benefits and doctor.
      -Angelina F., VSP

  • Doug says:

    How do SunSync Drive XT lenses perform around the house where there’s plenty of visible light? My house is light and bright. Won’t the lenses be dark most of the time? If I’m unhappy with SunSync Drive XT lenses, will VSP replace them with photochromic lenses rather than standard clear lenses? That seems reasonable since I want and will have paid for lens that darken.

    • Angelina F. says:

      Hi Doug,
      These are activated by a combination UV and visible light so typically they should stay clear indoors. Every pair of SunSync lenses comes with a one-year 100% satisfaction guarantee and if they don’t perform as you expect, you can exchange them.

  • Katrin Sukarso says:

    Where these lenses available now? Will Costco carry them already?

    Thanks

    • Angelina F. says:

      Hi Katrin,
      SunSync Drive XT is available through VSP Providers. You can find a doctor near you using the Find A Doctor Search on vsp.com. While Costco is an affiliate provider for some vision plans, there labs don’t process SunSync Drive XT at this time.

  • Michael says:

    Are these available polarized also? I use my glasses on the bike and in the car along water and in high glare environments, so this is important to me.

  • Bob says:

    so pay the premium for them, and at the end of a year if we’re not satisfied they’re replaced with standard lenses?

  • Natalei says:

    Are the lenses dark at night time?++

  • Jeri Marks says:

    How quickly do the lenses lighten up when going from outdoor to indoor?

  • James Baker says:

    Will they darken at night as a result of oncoming headlights or are they usable as clear lenses for night use? I always get 2 sets, one dark and one clear.

  • Anna Wojciechowska says:

    How much more do they cost v.s. clear lenses ?

  • Rick Melton says:

    Are these lenses polarized?

  • Anita Connors says:

    Is there a polarized version of this lenses?

  • Todd says:

    I wonder if they get darker in the car than Transitions Xtractive? Those were a NO-GO for me as the tint they got in the car–while darker and maybe acceptable to youthful eyes– was not nearly dark enough for my middle aged eyes. Back to eyeglasses and seperate sunglasses (1 month ago).

  • nize says:

    is there an extra-active lense available with polarization?

  • Sharon says:

    I do wear transition lenses to begin with. They get dark some but not all the time. I am far sighted. Should I change to another type or what.

    • Angelina F. says:

      Hi Sharon,

  • SusaN says:

    How do they work for night driving?

    • Angelina F. says:

      Hi Susan,
      The tint is activated by a combination of UV and visible light so they should remain clear at night.
      -Angelina F., VSP

  • Denise clark says:

    I’m getting my glasses this weekend. Is there a cost for these type of lenses? Would like ro not have to wear sunglass clips when driving

    • Angelina F. says:

      Hi Denise,
      I’d recommend looking into your vision benefits before you head into the eye doctor’s to see what’s covered under your plan.

  • tony says:

    Does incandescent or fluorescent light activate SunSync Drive XT?

    • Angelina F. says:

      Hi Tony,
      These do not activate solely from visible light but in combination with UV so they are typically clear indoors.
      -Angelina F., VSP

  • Lisa says:

    I tried to Google where they are sold but couldn’t, guess I have to call doc to see if they carry yhem

  • Rodney Owens says:

    I have had mine for 2 mouths I love them never have any other kind.

  • James Owens says:

    Will they darken indoors reacting to bright can lighting in a kitchen for instance?

    • Angelina F. says:

      Hi James,
      These lenses won’t darken based on indoor lighting alone, they also need UV rays to activate the tint.
      -Angelina F., VSP

      • James Owens says:

        I thought they worked in a vehicle where there is no UV light that was the reason to buy them. “SunSync Drive XT on the other hand activates based on exposure to UV and visible light. So, when you get into your car and the windows block the UV, the visible light coming through still activates your lenses.” Now I am really confused!

  • Teresa says:

    Wow! This is just what I have been hoping for! Transitional lenses do not darken in the car so I always clip on my sunglasses to drive. Would love to give them a try at my next appointment

  • Susan M says:

    So to my understanding they get darker due to visible light as well as UV light. So, what keeps them from changing while indoors under household light, or in the work place with Fluorescent lights? Thanks

    • Angelina F. says:

      Hi Susan,
      The tint activates based on the combination of the two. They won’t darken from indoor lighting alone.
      -Angelina F., VSP

  • Michele V. says:

    Will these lenses work well for someone who is night-sensitive, to headlights, etc?

    • Angelina F. says:

      Hi Michele,
      At night these glasses would remain clear because they are activated by a combination of both UV and visible light. Your eye doctor can help you best determine what type of lenses will fit your needs. If you don’t have an eye doctor, you can find one on vsp.com using the Find a Doctor Search.

  • Marsha S says:

    How do SunSync Drive XT lenses respond when someone takes a picture of you indoors? Traditional transitional lenses I know of turn slightly dark in a photograph taken indoors.

  • David says:

    Do SunSync glasses stay AS dark in a vehicle as they are outdoors? Do they ever get completely clear indoors, such as inside a grocery store with bright overhead lighting?

    • Angelina F. says:

      Hi David,
      They should stay about as dark in the car during with daylight, and return to clear indoors.
      -Angelina F. VSP

  • Deanna Burghardt says:

    what about night driving – glare from oncoming traffic headlights

  • Tuan L. says:

    For me who has never wear transition glasses like these, will they cause any fatigue or any other eye problems wearing these and going between sunlight and shade?

  • Irene says:

    Wish I’d known about these a few months ago. I just got new glasses over the winter 🙁

  • Shawn says:

    So would they get dark inside stores with bright lighting?

    • Angelina F. says:

      No, the tint won’t activate from indoor lighting alone, but the tint could become activated slightly from sunlight coming in through outdoor-facing windows.
      -Angelina F., VSP

  • Barbara says:

    Do we have to pay for it or is it free???

  • Margie BD says:

    This sounds like a fantastic improvement for driving! However, I have a question about wearing these lenses indoors and when there is some sunlight coming in through the windows. Will the SunSync Drive XT lenses also darken indoors? One thing I did not like about standard light-reactive lenses was that they always remained somewhat tinted dark while indoors. I never saw myself in untinted colorless lenses during the day and I found this annoying. I live in Florida, where it is always sunny.

    • Angelina F. says:

      Hi Margie,
      Depending on whether or not the windows have any tinting or UV filtration your experience could vary. The lens tint is activated by a combination of visible and UV light. SunSync lenses come with a 1-year 100% satisfaction guarantee for VSP members, so they could be worth a try.

  • Rick Reynolds says:

    Do these lens become completely clear inside? This has been my complaint with light-reactive lenses, inside they are still slightly tinted and make my eye area appear dark.

  • Chris says:

    Are they effected by cold? some photo chromatic lenses go dark when they are subjected to cold climates, e.g. sunny day in the winter in the northeast.

  • Randy Darnold says:

    will these lenses filter the same light waves as polarized sunglasses?

  • Renee says:

    If SunSync Drive XT lenses get dark inside a car, will they also get dark inside a building when there is bright light coming from windows or bright electric lights, either during the day or at night? What about outdoors in the shade?

  • Shelley says:

    How long is the risk free offer for? My next appt isn’t until Oct or Nov. Will is still be valid?

  • Mary Martinez says:

    Is this compatible with any other lense treament or filters? I work at a computer so I need blue light block.

  • Orlando says:

    How much does this SunSync Drive XT cost so I know my VSP network eye doctor won’t be over charging me?

  • Debra Lance says:

    I am switching to bi-focal lenses. Will this work with them?

      Hi Debra,
      No, Sunsync Drive XT is only available for single-vision and progressive lenses.

    I am honk and his is wonderful! I don’t like having to switch glasses and my other transitions aren’t dark enough.

  • Debra Lance says:

    I am switching to bi-focal lenses. Will the SunSync work with them?

  • Tyler D. says:

    If they react to light, then how do they perform with indoor lighting? I wouldn’t want my glasses darkening in my home or office. Also with that said I would imagine they may take longer to lighten up in those situations. Can you speak to this?

    • Angelina F. says:

      Hi Tyler,
      They turn clear indoors as they need a combination of UV and visible light to activate the tint.
      -Angelina F., VSP

  • Norma says:

    This is awesome news!! I have transitions and the negative side to them is not staying dark in the car. I still carry a pair of prescription sunglasses to change to when I get in the car, this is wonderful news!!! My eyes are light sensitive and I need the dark lenses on a sunny day!

  • Mark Pipes says:

    Sounds great. Do they come in glass? I currently wear Zeiss glass photochromic lenses. I refuse to wear plastic, all plastics have the optical property of mud.
    If they don’t come in glass, I will continue to wear my polarized sunglasses while driving, or while outdoors for a prolonged period.

  • Lloyd says:

    Sounds good. How much do they add to the cost as opposed to traditional light-reactive lenses?

    • Angelina F. says:

      Hi Lloyd,
      The pricing will depend on your vision benefits or the doctor’s office if you are not using insurance.

    If they respond to visible light then what stops them from going dark inside?

  • Don Faulk says:

    Want more info please.

  • Kathy says:

    Are the SunSync Drive XT available with a no-line bifocal?

  • Tom says:

    Do SunSync Drive XT lenses offer night time clarity for night driving?

  • Mark Pipes says:

    Is this a coating, or integral to the base material?

    • Angelina F. says:

      Hi Mark,
      SunSync Drive XT is not a lens coating. Your prescription is ground into lenses that are embedded with SunSync Drive XT.

  • Joe Loscalzo says:

    This sounds remarkable, i have transitions now….will these new lenses make them outdated/less useful?

  • Ray Esping says:

    How will these react to a bright sunny day in a boat with a canopy and the sun glaring off the water?

  • Ray Esping says:

    Are these available in all types of frames?

    • Angelina F. says:

      These lenses are compatible with most frames that you could typically add a prescription lenses to. -Angelina F., VSP

  • Thanh says:

    Transition lens is not dark enough to cover the bright sun while driving

  • Susan says:

    Does VSP ever answer any of our questions?

  • Dave says:

    Blue light protection is mentioned, is this a secondary benefit that is always in effect regardless of tint?

  • Ervin Wyatt says:

    What about on a Motorcycle wearing an Helmet?

    • Angelina F. says:

      Hi Ervin,
      The activation process that makes SunSync Drive XT dark is a combination of UV and visible light, so if the shield on your helmet provides UV protection it could prevent them from reaching its darkest tint.
      -Angelina F., VSP

      • Ervin Wyatt says:

        Yes all shields on Motorcycle helmets have UV protect, just like the Car Windshield. and unless tented provides the light just like the car windshield. So it sounds like it would work but might not get as dark.

  • Tom says:

    I see you say these new lenses work in a combination of light and UV rays. So if the auto glass block UV rays, how do they become dark while driving with all the windows closed?

    • Angelina F. says:

      Hi Tom,
      The activation process that makes Drive XT dark is a combination of UV and visible light. Windshields block UV light, but the amount that each windshield blocks varies. VSP members also receive a 1-year 100% satisfaction guarantee on SunSync lenses, so if they don’t meet your needs you can exchange them for regular lenses.

    How Long does it take for an answer for your question? I really would like an answer or is it that you don’t want us to know?
