If contact lenses or its solution cause Blepharirist, how long will it take action?

if contact lenses or solution cause Blepharirist, how long after putting it in and removing it out, will our eyes start itching? Immediately or more than 12hours later?

If contact lenses solution passed 90days from first opening, what will happened to it? If this cause Blepharirist, is new bottle ok, when I back to use contact lenses again?

I've neverf worn contacts (78 yo) and I've had Bleph for about 25

years.   I always thought it was because I wore eye make-up and maybe didn't clean as well as I should have.......but.....when my brother-in-law who is an opthamologist told me he had Bleph I knew it wasn't

make-up either.  I don;t know the cause...maybe just picked up

a bug on our hands and rubbed eyes?????

Yes, dear. I worn some make up for my cousin wedding few days ago. My condition still same with n without make up. How is ur Blepharirist now? How long can u mange it? Is it bother u everyday or sometime can it clear up?
