I am ust sorry that David is having to go through all this.
Lynn is, of course, right. Lenses that 'blink' out easily are part of the settling experience common to many KC fits. I think it has something to do with the lower edge of the lens sometimes being clear of the eye so that when the lower lid catches it in a blink, out it pops.
I had a similar problem, but in my case it did settle down.
Under no circumstances should David stop blinking!
it can be quite funny when the contact lens wearer suddenly says, 'nobody move' and the whole room falls to its knees and starts feeling the floor for something round. In my case the 'room' once contained a gaggle of RC and Anglican Bishops and Archbishops as well as the Moderator of the General Assembly. The only person who wasn't on his knees seaching for the lens was the one who had lost it!
Can somebody explain why lenses always land 'open' side up?
