From dark to light and light to dark, transition safety lenses (like HexArmor's Variomatic lens technology) automatically adapt to changing UV light, darkening when outdoors, and returning to clear when indoors or in the shade.

We get a lot of inquiries about our Variomatic safety lens (often thought of as "safety sunglasses"), so let’s dive into some frequently asked questions and the advantages of transition safety glasses to help you find the safety eyewear lenses that are right for you.

Popular questions on transition safety glasses

1. What are photochromic safety glasses?

Photochromic is another word for transition (or Variomatic in HexArmor® terms), and these types of lenses transition from a lighter to a darker tint with different exposures to UV light.

2. What are Variomatic lens?

Variomatic is HexArmor’s lens transition technology. Applied as a lacquer, Variomatic safety lenses are designed to be nearly clear when not exposed to sunlight and progressively darken when exposed to various concentrations of UV light. They come in two different styles, regular and dark (more on this later).

3. Are transition safety glasses bad for your eyes?

No, and in fact, the opposite is true. Transition safety glasses can help ease the strain on the eyes as they automatically adjust to various lighting conditions, helping mitigate potential headaches, eye strain, or worse.

Additionally, the majority of safety eyewear on the market protects against 99.9% of UV rays. For more advanced protection, all lens options in HexArmor’s safety eyewear lineup offer 100% UV protection.

4. Can you wear transition lenses while driving?

Yes, you can wear transition lenses while driving. However, if you are looking for protection from glare or brightness, you may want an alternative, as windshields are designed to block the UV rays that cause transition lenses to darken.

In these situations, we recommend our Variomatic Dark safety lenses, as the lenses are already tinted.

5. Can transition lenses be anti-fog and scratch-resistant?

You can find both of these added benefits in safety transition lenses. However, not all of these types of coatings are the same; make sure to research the technology used to find the best solution to fit your needs.

6. Can you wear transition safety glasses at night?

Yes, you can wear transition lenses at night as they will be nearly clear, and you’ll get the same safety protection against environmental debris with or without UV exposure.

We recommend our standard Variomatic lenses for this situation.

7. Are transition safety glasses worth the money?

This depends on your situation. If you are frequently going inside and outside, transition safety glasses can help keep you in compliance and mitigate eye issues – especially if you are mandated to wear safety eyewear.

You only need one pair instead of many to accommodate different light environments, which keeps the eyewear on the face, leading to a reduction of injuries.

Why Variomatic transition lens tech is a must-have

HexArmor’s Variomatic lens technology has some unique characteristics that help workers going between indoor and outdoor environments stay comfortable, productive, and compliant all day long.

One pair vs. many

With safety eyewear in particular, it’s easy for workers to forget them or not have time to grab a new pair. But with Variomatic lenses, there's no need to switch between multiple pairs throughout the day or carry more than one pair – keeping more safety eyewear on more faces for longer periods.

Promote eye health

Over time, transitioning from inside to outside or working in different lighting conditions can take a toll on your eyesight or productivity, not to mention the temporary blindness that can be caused by stepping into bright sunlight. The fast transition times with Variomatic help lessen the strain on your eyes, allowing you to keep your vision uninhibited.

Cost savings

In our experience, these lenses are taken care of better due to pride of ownership, which leads to better cost in use, reduction of injuries through increased longevity, and SKU reduction from the eliminated need to stock multiple tints.

Permanent anti-fog coating

Standard on our Variomatic lenses is HexArmor’s signature TruShield® coating that offers permanent anti-fog and scratch resistance coatings, as well as 100% UV protection.
