I have sensitive eyes, the kind that tend to be red around the rim whether I've partied or not. As I've gotten older they've gotten drier and become even more sensitive. They look like my mother's. She suffered from the same problem and was a big consumer of Visine
I scoured the shelves of several drug stores looking for them to no avail. A stop at Sephora was met with a horrified "We wouldn't sell anything that you actually put in your eyes."
Then one day when I was sorting out the available eye drops at my local pharmacy there they were, a standout in an attractive oval acrylic and green container. 5$ on the counter and they were mine.
And yes they do work. My eyes feel refreshed, they look clear, the whites a blue white with nary a speck of red. "Turn around bright eyes"
