What’s the difference between photochromic and Transitions lenses?

Let’s get this out right away. Transitions™ lenses are a brand that makes Photochromatic lenses. They have simply become so popular that the two words have become interchangeable. On top of that, Transitions have become one of the most popular and advanced types of lenses that have a host of benefits for the users who get them. 

Why should I get photochromatic lenses?

Here’s how they work in principle. When your lenses are exposed to UV rays (not light that many assume), the lenses have these molecules that will start to darken. So eventually, the lenses’ color will darken, and they will be akin to sunglasses. But also, at the same time, they act like sunglasses, protecting your eyes and eyesight from harmful UV rays.

When you step indoors, outside of the harmful rays, they will transition back to clear lenses so you can see normally indoors. Hence the name is commonly known as transition lenses. There are some things to note, though. Photochromatic lenses don’t work great when driving a car, as the windshield blocks out the UV rays. 

However, there are some photochromatic lenses that do work specifically while driving a vehicle, so be sure to inquire about those. Another thing to note is that they don’t work as fast in colder weather conditions, as is common with any molecule working slower in a colder environment. 


These frames and lenses are nonprescription safety glasses that meet OSHA compliance and have impact-resistant lenses, as well as ANSI Z87+ approval to round out the protection. What makes these great is that they are perfect for those who need to quickly transition from indoors to outdoors and vice versa.

In addition, they’ll consistently switch the lens color to adapt to the current lighting and UV ray conditions to always ensure that your eyes are focused on the task at hand. The PSG-TG-206YBS also comes in a stylish black and yellow color, meaning you can have your safety and style at the same time. 


Another ideal nonprescription frame that comes with photochromatic lenses gives the adaptability one needs in the workplace. These safety glasses also come with the transitional nature of the lenses, and they’ll have different stages of gray until they essentially become sunglasses. 

In addition, the PSG-TG-P820 is constructed with TR-90 Nylon, making them the ideal lightweight choice for all-day wear. The lenses themselves are also OSHA compliant on top of the ANSI Z87+ impact and velocity ratings. 

These come in a wraparound design to ensure a snug fit but also side protection, which, combined with the rubberized nose pads, means no slippage. In addition, they come in a standard black frame.

Photochromatic lenses are for everyone

The next time you hear about transitional lenses, just know that it’s really the photochromatic component. They aren’t just dedicated to those who wear prescription glasses but have since been adapted to prescription safety glasses and nonprescription safety glasses to ensure that safety and visibility are always a top priority.
