A few photos in 24 Celsius sun comparing colourtouch Amber with Photofusionx Burgundy. We are forecast to have 30 degree heat this weekend so the contrast in not just sun but heat may show up more.

For now, my ‘hypothesis’ is that as transitions colourtouch have a c25% base they will remain darker even in heat. These photos compare colourtouch (amber) with transitions (burgundy), both at full activation.

They are pretty similar but to me the amber does seem to go a bit darker - that may just be the difference between the tint colours, but for instance I can face the sun with the colourtouch amber with slightly less glare.

(Edit: both frames are Masunaga One Hundreds… different colourways).

So it is finally out! I think mainly worth it for varifocals, and it costs (at Simplespex, who do not rip you off) £100 more than Smartlife superb…. The Zeiss description of the new tech including research results is really promising.

So I said I would post once I had them, and did so using another account as Reddit was being painful about this one about a comment taken out of context (not sure they get sarcasm… or humour…)

Anyway this should show colortouch sapphire (i shifted from black to champagne TVR 504 crystal frames as in black acetate they just looked washed out) and amber in Masunaga One hundreds (black/demi - the lower brown in the frames picks up the same tint).

Comments:

- 25% wash now certain (had heard rumours of 35%)

- works fine in certain thick acetate (for black I might suggest Ruby) and more will certainly work in most rimless or wired frames

- goes as dark as any transitions (unsurprising). I will only know if they go a tiny bit darker after a more time in the sun when they are fully bedded in, otherwise, 30 seconds to full activation, maybe 90 back to base tint.

- as the gradient is 25% to zero this will be VERY subtle.. rimless or similar may be the frames for such a light gradient?

Happy to answer any questions if I can!

P.s. these are in Essilor Varilux XR varifocals at 1.67. But they seem to be available across the Essilor range, and some of the Essilor licensed companies make cheaper lenses with the same tech, and Goldie has found one which even offers the standard brown, grey and grey/green under a non ‘colortouch’ brand…
