The first attempt was too dark. I sent the optometrist the standard images we've all seen and she just kept creating samples until I was satisfied. Even then I had some trepidation when they arrived but I think she did a really good job.
She sends me images on a white surface, on a mannequin & held up to the light.
Some of the images online lean towards the blue and others towards the red/pink of the purple scale so it was quite a lengthy process to get the tint where I said "go for it"!
Patience was certainly a virtue on this occasion, but worth it.
just got the first version of the fulton vonzipper in france for 30 euros, I think it’s too good not to be a fraud but it was worth a try, I’ll find out when I get them
