Question

I just found that there is a kind of transitions drivewear in costco. Is it expensive? How much does it cost? Can it be good for driving at night?

Answer 1

The Transitions drivewear designed specifically to meet the unique visual demands of the driving task. It is combining the advantages of Transistions and polarized technologies. Transitions Drivewear lenses are the first photochromic lenses to darken behind the windshield of a car, allowing Drivewear to change color based on current driving conditions in order to enhance the driver’s vision.  In addition, Drivewear lenses are polarized to block blinding glare, another distinct advantage when driving a car.

Moreover, the price varies the lenses you choose. The Costco associate says high-index 1.67 lenses costs $100. I blinked twice and then asked again are you sure? Aren't there additional costs for scratch resistance and anti-reflection and UV protection? He replies no. Costco's high-index 1.67 lenses include scratch resistance and anti-reflection. And if you want transitions drivewear, it might cost you more than $100. Hope this helpful.

Answer 2

The Transitions drivewear sold in Costco adapts to changing daylight conditions continuously. It reduces excess light and optimizes color contrast and is polarized to block blinding glare. 

In light or overcase conditions, the lenses are green/yellow color that can provide high contrast and minimized glare. When you wear it in the car or behind the windshield, the lenses activate t a copper color, which will enhance color recognition and depth perception. When it comes to bright outdoor light, the lenses activiate to dark red-brown, which will filter excess light to provide maximum comfort. 

Should transition driverwear be used at night? The answer is no. Since transition driverwear lenses will revert to a clear state in the absence of UV light, they offer no protection from road glare when it gets fully dark. Like all photochromics, they are purposefully designed so that they do not react to artificial light sources like headlights and streetlights. To address nighttime glare, you should consider a pair of glasses with an anti-reflective coating, utilizing either clear or yellow lenses.
