ROFL!
Just thinking of Ken sitting in the pub after the London group meeting with his burger and chips and glass of white wine and trying to imagine him eating a plate of scleral lenses!
Or, for breakfast, maybe sclerals on toast with his cappuccino. (OK, you spell the stuff!)
What a vision.
Seriously......
If the rainbows are there as soon as you put them in if you look at a right light, that would suggest to me that it is some sort of chromatic abberation effect from the combined shape of the lenses and your eyes, rather than a health effect of having been wearing the lenses for any length of time.
BUt I'm not a specialist and I haven't seen your eyes or your lenses.
If your specialist isn't orried about it from the point of view of your eye health, that sounds encouraging.
But if the rainbows bug you - for example, if they are distracting while you're driving or working - then please go back and ask again about them. And meanwhile please be careful - we don't want you having a rainbow-edged accident.
