3 Simple Tips For Picking The Perfect Light-Reactive Lens Color

By on

So you’ve made the decision to try light-reactive prescription lenses. Now the question is: “Do I choose gray or brown?” To simplify your decision, you’ll want to consider the following three factors:

1. Frame Color

Prescription glasses not only provide vision correction, they’re also a fashion accessory. When deciding on a lens tint, most eyeglass wearers consider frame color the most important factor. The same way color combinations play an important role in our wardrobe, nobody wants lenses that clash with their frames.

So what’s the secret to coordinating an attractive lens and frame ensemble? A good rule of thumb when selecting a light-reactive lens color is to go with gray lenses for cooler or neutral frame colors like black, white, gray, silver, chrome and blue. Brown lenses are a better option when pairing them with warmer frame tones such as brown, gold, tan, yellow, green and red.

2. Darkness

If you want the darkest lens possible, go for gray. In premium light-reactive lens brands such as SunSync , gray lenses block out more light than brown lenses.

3. Contrast

If you’re looking for better contrast to improve the sharpness of your vision, brown lenses will do the trick. Brown lenses accentuate greens and reds, enhancing contrast and sharpness in the sun. This makes them a perfect fit if you golf, fish or participate in other outdoor activities where contrast is key.

 A Final Consideration

You may be asking, “Is gray or brown better when indoors?” The answer is neither. Both turn clear when you’re out of the sun, so there is no difference between brown and gray indoors or at night.

Ask your eye doctor if light-reactive lenses are right for you. As a VSP member, your benefits provide a savings of up to 40%* on SunSync light-reactive lenses.

    I don’t know if there is a good solution to this, but I find the most annoying thing about these types of lenses is that when I’m driving, the lenses turn nearly clear, thus leaving the problem of glare from the sky and road unsolved. what would you suggest?

    • Dennis Anuszewski says:

      Transition lenses work great every where except driving due to the UV coating on the car’s windows. I use an inexpensive pair of fit overs for driving. That takes care of the problem.

    • David C says:

      Hi Anne – It is recommended to have a second pair of dedicated driving sunglasses kept inside the car, in a console or glove compartment out of direct sun and heat. Photochromic lenses are ideal to have on your everyday glasses to offer brightness protection when frequently going in and out of doors such as at school or out shopping.

      • Anne Mester says:

        Thanks. I do have those, but was hoping there were lenses that would cover this situation. Apparently, maybe there will be soon!

    • Michelle Doutrich says:

      I have the same issue. I always buy only prescription glasses that come as a set with magnetic sunglass clips – they match the frames of the glasses and are easy to take on and off in the car.

  • Bonnie Beane says:

    Thanks for this info ~ eye appointment’s coming up next month.

  • Jody Hudson says:

    Question: How well will these work inside a car? Even a clear windshield will block some of the UV that causes the lenses to darken. Most windshields these days have a slight tint. Does the amount and color of tint have an effect on the darkening of the sunglasses? Are some color sunglasses affected more or less than other colors by the UV-blocking effect of a windshield?

    • David C says:

      Hi Jody – Even clear car windshields block nearly 100% of UV light so photochromic lenses do not activate inside the car. There will be new photochromic products coming in the near future that are slightly tinted at all times including inside the car and get very dark when exposed to UV light.

  • Paul says:

    When you say both lens turn clear when out of the sun, what does that mean? Do the lens become 100% colorless? I had these type lens in the 1970s and early 1980s, and they were not colorless inside.

    • David C says:

      Hi Paul – Both colors allow about 96% light transmission in the clear state. The very faint residual tint is virtually imperceptible to the eye and can only be seen if the lenses are placed against a pure white background.

  • Which color is best for driving, night vs day?

  • Mack says:

    I have had the gray light sensitive “Transitions” for years. They are wonderful for every situation except driving. They tend to lighten when in the car no matter how bright of a day it is in southern California. So this year I am getting prescription Sunglasses just for when I am driving!

  • Art says:

    I found the article on how to choose the right color lens to color of a frame very helpful. Thank you

  • Charles Rodriguez says:

    Very informative and timely, I am shopping for transitionl lenses for the first time and learned a lot from your article !!

  • Hernan Gomez says:

    Excellent long and short of reactive lenses. Please include in the future the new green-graphite lenses. My experiece with them is that colors are brighter yet cooler than brown but not as dull as grey lenses. Reminds me of the G15 green lenses that you would see on the pilot sunglasses.

  • Jack says:

    Very useful information.

  • Stephan says:

    I tried photochromic lenses twice. The first pair barely changed at all. The “new and improved” version was better but not by much. My experience proves to me that Photochromic sunglasses don’t come close to giving you the eye protection you get from a simple pair of high quality sunglasses.

  • Martha says:

    I have transition glasses with the photogray that turn black outside and stay pretty clear in the car as mentioned above. My fix is that I have magnetic dots on my glasses that I can clip on in the car when it is really bright. Fixes all the sunlight problems. You get used to the dot after a while being on each outside edge of the glass lens. This really is the answer.

  • Mehran Habibi says:

    I have had Transitions glasses for many years and had no issues with it. I love it. Regarding the driving in the car, apparently the car window blocks the necessary light (whatever that is!) from penetrating so the Transition lens doesn’t work. Alternative and easy solution is to add the clip-on or to wear those HD glasses over your prescription. Not a big deal.

  • Martha says:

    The solution is this. I purchased my last glasses with a magnetic dot on each lens on the outside edge of the glasses. I love the photograys, which are clear inside, up to black outside, but when I am in the car or outside in really bright sunlight I click on another plastic lens that works in the car. It took a while to get used to the dots, but I no longer have a problem seeing it as an annoying thing.

  • Julia Ebarb says:

    Transition lenses DO NOT WORK when in a vehicle or somewhere where there is any kind of UV filtering in the glass. To me this makes them a total waste of money. I have had to purchase a pair of sunglasses.

  • tom wheeler says:

    Will these glasses turn darker if I am driving my car? I hear they wont.

  • Kathleen Beaudoin says:

    Google “Dioptic Sunglasses.” They fit over your glasses and block the sun from the front, top and sides. They are not expensive – about $30. I have had mine for 2 years and they are a god-send.

  • Diane says:

    As already mentioned, photochromic lenses do not work as sunglasses while driving because the windshield blocks the sun’s rays. So I purchased prescription glasses just for driving, but it took two tries to get it right. My second pair of driving sunglasses have a gradient lens, which allows me to better see the dashboard controls (through the lighter part of the lens). My first pair were universally dark and I could not read the dashboard during the day.

  • Edith Schauble says:

    For the car one can use the “clip on” sunglasses. Works very well Edith

  • Tints don’t certainly matter for normal activities, what matters is not being fooled by buying $400-$500 fames which are just $4-$5 per frame.

  • Felix says:

    How about the so-called Graphite Green lenses (Transitions)? Pilots use green lenses because they supposedly have truer color perception and enhanced contrast.

  • Michelle says:

    I ordered a burgundy frame for transition lenses,I wanted a brown lens, the lady suggested grey.I have cataracts & I drive, & will be driving a trolley soon, which lends would be the best? would grey lenses go with a burgundy frame? I ordered them with grey lenses, may be I can hurry to change the lens color, please help.

  • Transitions xTRA are now available. They retain some tint even in the car AND they darken somewhat while driving in sulight for additional protection.

  • Michael says:

    Thanks Michelle. The blog very helpful
