About photochromic visors


What are photochromic visors?

Photochromic means something that changes colour in response to light. So, in the case of visors, that means a visor that will darken in response to UV light.

Which means it’ll stay light when indoors (indoor lights don’t transmit much UV apparently) or when it’s dark or a dull day. But when it gets sunny, then the visor will start to darken. And when it gets really sunny, it’ll do it quickly and get really dark – Lazer quotes an 80% tint for its Lumino visors.

How quickly do they change?

Well, photochromic visors are known to darken more quickly than they lighten and the speed it takes is slightly temperature dependent too. But, if it’s a really bright and sunny day, they’ll typically reach max darkness in about 20s – or about the time it takes to get on your bike, put your helmet on and set off. Which is pretty cool.

How do they work?

Most of the photochromic visors on the market today use technology developed by a company called Transitions – including those available from Shoei, Bell and Lazer (see below).

Transitions lenses use a light-sensitive dye to either impregnate or coat the surface (depending on the material). When exposed to UV light, the molecules in the dye change structure, causing the visor to darken.

For more info on how it all works, here’s a link to Transition’s technology page.

We’re great fans of photochromic visors – especially when helmets come with them in the box like the very reasonably priced Bell Qualifier DLX full face and Lazer Monaco flip-up (that’s SHARP 4 star rated too).

You’ll find helmets that come with photochromic visors in the box here on our photochromic visor page. Or read on…

Which helmets come with Photochromic visors?

At the time of writing, the following manufacturers either offer their helmets with a photochromic visor as standard fitment, or have one available to buy separately.

Lazer’s Lumino active photochromic visors are available for the Kite, Falcon, Osprey and Kestrel


Bell produces what it calls their Trinsitions SOLFX ClickRelease visor. The following helmets have one available to fit:

Bell Qualifier DLX – comes as standard with one in the box.

Bell Star, Vortex, RS-1 and Revolver – all ClickRelease compatible but not included.


Lazer’s Lumino visor system is their photochromic visor brand that also uses Transitions technology. Lazer say that at it’s maximum it is 80% tinted (i.e. gives 20% light transmission). It blocks 100% of UV and is anti-fog coated too.

The Lazer Monaco comes with a Lumino photochromic visor in the box. However Lazer also say you can also buy photochromic visors for the Kite, Falcon, Osprey and Kestrel helmets.


Shoei produces a Transitions adaptive visor for their CWR-1 visor shape which means it should be available for the X-Sprit 3, NXR and RYD helmets. Note none of these helmets come with a transitions visor in the box.

  1. As fair as I know photocromatic visors and inserts can’t meat EU regulations and are therefore technically not legal. Doesn’t really matter much given you could happily pull up next to police in a dark tinted visor and have a chat with them without them caring. But I believe this is why many helmet manufacturers or pinlock aren’t making them.

    Pretty annoying as it would be perfect for mixed use, especially with an internal sun visor in the summer, and avoid the need to change from a tinted visor to a clear visor at night.

    • I don’t have a copy of the ECE 22.05 regs to hand but the latest 22.06 regs specifically mention photochromic visors and specify a minimum of 20% transmittance (same as a standard sun visor) – so yeah they’re legal in Europe and other ECE countries, as long as they have the right certification stamps. That should be the usual E symbol in a circle followed by the country code with approval number stamped underneath.

  2. I have a question.. how safe are these visors when you enter a tunnel or multi-story car park? You say on a sunny day they’ll go from light to dark in about 20 seconds. Going into a tunnel at 60mph would worry me if I couldn’t see properly for up to 20 seconds because it was too dark. Does it react faster when going back to light?

    • HI Terry, I think it’s really down to personal preference. If you regularly ride in bright sunlight and go through tunnels or into (suddenly) dark places a lot, you might find you’re having to flip up your visor for a while to give it time to adjust. But in practice most riders don’t seem to have much of a problem and, where necessary, adapt quickly by flipping up their visors for a few seconds whenever there might be a problem. Many riders like them but the bottom line is that you’ll really have to try it for yourself to know 100%. Or if you’re unsure, go for a helmet with a drop down sun visor instead, then you’ll be 100% in control.

    • I wear one on my Shoei NXR and from the inside it doesn’t appear dark enough that you’d ever need to lift it up in tunnels. Tunnels are lit pretty brightly here and even in shaded areas the tint is great.
      It doesn’t go quite as dark as a full tint on a regular tinted visor, but the fact I can have one that works in night and day is a huge win for me.
