As a landscape photographer who needs to wear eyeglasses I find it useful to wear photochromics, but have had good and bad experiences with these over the years.
A few years back I had a pair where the photochromic tint was brown, but which gave white clouds on a sunny day a distinct and disagreeable pink tint.
My current pair are supposedly grey, but do have a slight blue tint. This is not so disagreeable: whites are not affected, and sometimes winter hues are enhanced in a manner which I'm happy to re-present in post-processing as it seems beneficial and not too extreme.
However, I'd like to make sure my next pair of specs have a genuinely neutral grey tint (analogous to identical values in R G & B "channels"). I've discussed this with my opticians, but am told the brand they deal in (Essilor) have a photochromic system (Transitions VI) in which the hue is variable and unpredictable straight from the production line. So I might be very lucky and get what I want; be less lucky and get an acceptable blueish tint, or be downright unlucky and be back in the world where the summer clouds shine pink!
Does anyone here have experience of this problem, and/ or know a brand of photochromics that simulates a neutral, untinted, greyscale effect (and preferably available in the UK or EU)?
Thanks in advance
