When can you wear photochromic glasses?

Auto glass has some UV protection, that may prevent photochromic lenses from darkening. These lenses contain proprietary dyes that undergo chemical changes and darken when subjected to UV light. Photochromic technology has come quite a distance since the very first transition lenses, which darkened when silver chloride or silver halide in the glass lens reacted with UV light. They darken even under cloud cover– Because the photochromic lenses darken because of UV light , they darken when it’s cloudy.

The glasses manufactured from this material are light and strong, so your ears won’t be uncomfortable when you wear them for some time. Sunglasses are ideal if you spend a lot of time outdoors, especially in pursuits like boating, fishing and skiing, where light is reflected off water or snow and glare can be intense. They are also very useful for all those with light sensitivity, since they darken a lot more than photochromic lenses do.
Photochromic lenses work by reading the intensity of ultraviolet radiation. On a sunshiney day, there are more levels of UV rays, which means lenses will be at its darkest. On cloudy days the sunglasses could have light tint because UV rays still get through, but not as much. Inside, where you can find no UV rays, the glasses will undoubtedly be clear. Photochromic lenses are versatile, it is possible to put them on indoors or outdoors and on sunny days or cloudy ones. The lenses darken or lighten with respect to the intensity of UV rays. Should you choose wear prescription glasses, buying photochromic lenses might actually save you money.

• Transitions® Signature® lenses meet up with the needs of most glasses-wearers and are perfect for everyday wear.
• They’re glasses lenses that transition from clear to dark when subjected to UV rays.
• For more driving needs, one style of photochromic lens is Transitions Drivewear, also produced by Transitions Optical.
• The primary concern glasses-wearers have with the Transitions® Signature® lens is that it doesn’t get dark enough in the sun; the XTRActive® lens solves that.

Vantage™ lenses align dye molecules to make a polarized filter that blocks glare. And while it generally does not get quite as dark as XTRActive®, the polarization produces a comfortable visual experience beneath the sun.
The lenses transition imperceptibly from clear to tinted and go back to clear in just a matter of minutes. Both photochromic lenses and sunglasses protect us from the sun’s harmful ultraviolet rays, that may damage the eyes. UV light has been linked to cataracts, macular degeneration and pterygium (also known as “surfer’s eye”), a pinkish growth or bump on the eyeball. Because the name suggests, Transitions® Drivewear® is optimized for behind-the-wheel. This color option is built to enhance contrast and bring out the details of the road. Drivewear® lenses may also be polarized to reduce glare from other cars, the road, and any other reflective surfaces you encounter during the drive. Overall, Drivewear® transition sunglasses are a perfect choice for individuals who spend a lot of time on the road, but are not the best for indoor use because they always have hook tint.

They tend to darken less dramatically in high temperatures than in winter, unlike sunglasses, which keep up with the same opacity level no matter temperature. The easiest way to choose Photochromic sunglasses would be to consult with an eye care expert. This way, you can decide which will work best for your eyes. You can start looking for transition sunglasses with anti-glare protection. We already know what Photochromic sunglasses are and how it operates.
So, they help enhance the quality of one’s vision by reducing the sun’s glare in various light conditions – on bright sunny days, on cloudy days and everything in between. Transitions® Signature® lenses meet up with the needs of all glasses-wearers and are ideal for everyday wear. They start as clear as traditional eyeglasses, then darken in line with the level of UV light present.
