I don't have any pain, but my eyes get tired. I find myself needing to rest them often. And I still use a lot of drops. The drops are no big deal, I can handle that. But the tired eyes, well, it's tiring. I've gotten a headache or two, but it's usually at the end of the day and is gone by morning.
I'm loving this. I can read, and go right to sleep. I can wake up in the middle of the night, and be able to see. I love love love this.
