Which Glasses Are Best for Driving?
Transitions XTRActiveTransitions XTRActive lenses are the latest in the range of photochromic lenses available for spectacle wearers. Manufacturers of lenses that react to brightness have been working hard to continue the development of the technology that enables lenses to react to sun light.
Improvements in this technology has resulted in photochromic lenses that have very little residual tint, in other words, are very clear indoors. Reaction times have also improved with the latest Transition lenses fading back to 70% light transmittance within 9 minutes from a fully darkened lens. Traditionally, transition lenses have always performed better in colder temperatures and have struggled to fully darken on warmer days. Until now, this type of lens has reacted to UV light meaning that when driving, the car windscreen prevented any real benefits from photochromic lenses for the driver.
The new XTRActive lenses have been developed to react to visible light and will now darken to 50% light transmittance behind the windscreen of a car, even at temperatures of 27°C.
When outdoors and at temperatures around 95°F the new Transitions XTRActive lenses will darken to 20% light transmittance, as dark as sunglasses. This compares to a light transmittance of around 27% in the same conditions when wearing the latest photochromic lenses.
XTRActive lenses retain a light tint even indoors. People that are light sensitive or that work in really bright environments may find this to be a benefit.
The new Transitions XTRActive lenses have a light grey residual tint and darken to a green-grey colour. As with all photochromic lenses, they block 100% of harmful UVA and UVB rays and provide UV400 protection.
XTRActive lenses are the darkest photochromic lenses available. They have a slight tint when indoors. They will darken moderately behind the windscreen of a car and are approved as suitable for night driving. They make very versatile spectacles.
So to answer the question, which glasses are best for driving? The latest XTRActive photochromic lenses with anti-reflective coating will help the driver in all light conditions. The glasses can be worn to drive at night due to the very low residual tint. They can be fitted to wrap-style sports frames to give even greater versatility, truly a pair of glasses for all occasions.
