You merely alerted Cid to your ability to see into his memories, and giving him the goggles was symbolic of showing that you were the one who managed to help him regain his memories in the church in camp drybone.

It's certainly not literally that your character travelled in time and gave him goggles. And Cid's "it was you.." was more him understanding that you have the power of the Echo and were just then able to see his past.
I like this it hurts my brain less and makes the most sense to me.
