Contact lenses question! Urgent!
Every time I travel I keep my contacts in the case and bring solution with me in my carry on, but I have bad vision so I can't put them in jeopardy. I don't see why there would be a problem with your contact stuff in checked luggage at all.
I just put my contact stuff in my toiletry baggie and then have no problems going through security.
Edit* the solution I bring is travel size
