Are there polarized transition lenses




















The greater the intensity of UV rays, the darker the lenses become. When UV light is no longer present, including indoors or at night, the lenses fade back to their original state. To fit every style, Transitions lenses are available in 7 different colors and 6 different mirror options. The technology that Transitions lenses utilizes is continuously improving. It is our darkest everyday lens, even in the hottest climates. No, you do not need to worry.

The technology behind our Transitions lenses ensures that the photochromic dyes are part of the lens and cannot be scratched off or peeled off and are designed to last for the life of your prescription. If you experience a problem with your lenses, we suggest you contact your eyecare professional or place of purchase. Transitions lenses are activated by UV light. The amount of UV light present will determine how dark your lenses get. This is what allows you to see life with just the right amount of light.

Extreme situations can sometimes cause your lenses to behave slightly differently. For instance, temperature can have an effect on the reaction time of adaptive lens technology. To learn more, visit Transitions lenses' technology page. Adaptive lenses react to their environment, so the level of darkness is affected by extreme temperatures, UV exposure, and lens materials.

Transitions lenses darken immediately upon exposure to UV light. The level of darkness will depend on the amount of UV light present, time of day, and direction of the sun. Transitions lenses begin to fade back to clear as soon as UV rays are no longer present. Transitions lenses are designed to last two years, which is generally the lifetime of your vision care prescription. In order to keep your prescription lenses current, regular, comprehensive eye exams are recommended to determine any prescription changes and help prevent any other eye problems.

Talk to your eyecare professional or eye doctor to find out how often you should schedule a visit to preserve your eye health. Polarized sunglasses also can be used to reduce reflections from the surface of water, which makes them very popular for fishing and water-based recreational activities. One example is the Transitions Vantage line of lenses. When these lenses darken in sunlight, they also become polarized.

The darker the lenses get, the more powerful the polarization effect. Determining whether photochromic lenses or polarized sunglasses are better truly depends on how you personally plan to use them. With transitional lenses, you can wear sunglasses while driving and still be able to read important street signs. Having only one pair makes it easier on you. Protects your eyes — Transitional lenses do more than function as sunglasses.

They actually filter out a good deal of the harmful UV rays emitted from the sun, leading to healthier and happier eyes. The cons So does the bad outweigh the good? These are some of the drawbacks of photochromic lenses: Ineffective in cars — Photochromic lenses darken in reaction to UV rays, which your windshield blocks. Differences in brands — Another issue that can arise with photochromic lenses is that different brands have different levels of darkness and different reaction times.

Speaking with your eye doctor about this can help you find the brand that works best for you. While most Transitions lenses will not darken at all in a car, this Transitions Vantage lens will darken slightly. When this lens is not exposed to UV light it is clear and not polarized.

Completely clear lenses are never polarized. The Transitions Vantage does not get quite as dark as a typical Transitions lens, but because the polarization is blocking glare you might believe that it is actually darker than it is.
