Hi Ken,

Apologies for the very slow reply, I was out of the country for business for some weeks. Your question was do they give any sort of irritation. None at all, and in fact, I often think the lens has fallen out because i can't feel them. I actually asked my doctor about this, and he said that this is common, because the design is so closely matched to each individual's eye.

Since I last reported, several of my colleagues have been fit in the lens and absolutely love them.
I hope this helps,
