Will transition lenses work inside a car?

Transition lenses are designed to respond to UV light exposure, which is what triggers them to darken when exposed to sunlight. Inside a car, the UV rays are significantly blocked by the windshields, which typically contain materials that filter out these rays. As a result, transition lenses do not receive the necessary UV light to activate their darkening feature while inside the vehicle.

This characteristic of the lenses means that while they are effective outdoors in bright sunlight where UV rays are present, they will not behave the same way in the filtered light of a car, limiting their functionality in that environment. Thus, the correct response highlights this limitation specifically related to the conditions inside a car, providing clarity on how transition lenses operate under different lighting situations.
