Glasses that Turn Into Sunglasses: What’s the Catch?

Prescription glasses that turn into sunglasses. Ever heard of such a thing? Yes, it exists. Thanks to expert and innovative opticians who thought of such an idea, transition lenses help you move in and out of the sun comfortably. They save you from the hassle of switching your glasses and sunglasses again and again. Well, they can do this because transition lenses can change their tint color from clear to dark when you step out in the sun and vice versa. 

What’s the Science behind it?

These glasses that turn into sunglasses have molecules layered over them in the form of a coating. While in other lights, this coating remains transparent, it reacts and changes color when exposed to UV rays i.e., the sunrays. They change into a dark color because of absorbing energy from the light spectrum. 

And as you proceed indoors after being outdoors for some time, the intensity of UV light gradually lessens because of which the molecules can no longer react and turn back clear. If you are wondering if they react to artificial lighting? Well, they don’t. So there’s no chance for the glasses to ‘mistakenly’ turn dark inside.


Now, the color of the tint varies based on the amount of UV light that the lens gets to absorb. That’s why these glasses are not quite effective when sitting in a car. The reason behind this is the new age glass used in car windows that prevents UV light from entering.
