(Question) Has anyone used artificial tears?^^

My son had LASIK surgery a few years ago~

They said glasses would be uncomfortable if I go to the military..

Maybe it was because I was on a three-shift duty in the military and my eyes were tiredㅠ
About two months after enlisting, I asked to send artificial tears.
Since I was also using artificial tears, I used to send disposable artificial tears, right?

Since when, I saw the artificial tears my son uses.
Is it not disposable?
I heard you're using artificial tears in a small bottle...

I ran out of artificial tears, so I borrowed a drop from my son and tried using it.

I almost screamed..ㅠㅠ

Does it feel really hot?
Do my eyes feel like they're stinging?

I couldn't open my eyes for a moment~
I keep having nightmares after LASIK..ㅠ

My son said the view is refreshing... I wonder if my son is using something too strong? ^^;

It seems like a regular artificial tear upon searching.

I didn't try to stop it anymore...
Is it just me, or is it only in my eyes?^^
