Transition lenses. They’re one of the more influential developments to hit the eyewear industry in the last several decades.
With transition lenses (also known as photochromic lenses, their technical identity), your glasses automatically darken in response to the amount of UV light that’s present, and clear again when that source of UV light is gone. In other words, they’re the ideal combination of prescription glasses and sunglasses – clear at night or when it’s cloudy or shady, dark when outdoors in the sun. With transition lenses, one pair is all it takes to cover all light conditions.
You may be new to transition lenses and are just starting to research them. Or you may already use and enjoy them. Either way, you’ll soon discover (if you haven’t already) one of the primary drawbacks of photochromic lenses: they do not fully darken inside a car. This fault lies not with the lenses but with the car’s windshield; automobile windshields are already designed to block UV light, to protect the car occupant’s eyes as well as the car’s interior. The only UV light present in a car is that which filters in through the side window glass, and usually it’s not enough to trigger photochromic lenses.
This can be problematic for many, as daytime driving is one those activities where sunglasses are most useful. Options, such as sunglasses that fit over or clip on to your prescription glasses, are available, but people often ask if there are any kind of photochromic lenses that do darken inside of a car.
The answer is yes, and they’re called DriveWear lenses. DriveWear was developed by the Transitions corporation, the creators of transition lenses, in response for this particular need. DriveWear lenses feature photochromic molecules capable of reacting to both visible and UV light, as opposed to standard transitions, which react only to UV light. Because of they also detect the visible light spectrum, DriveWear lenses can sense and adjust to light conditions both inside and outside of the car. This makes them the ideal lenses for driving – all kinds of driving, from the full glare of midday to the middle of the night, and all light levels in between.
