If you wanted to sell them eyedrops that were made in the USA but which cost them an extra 5 cents/bottle, they would say NO.
I had no idea even eyedrops were made overseas. Sheesh. It shouldn’t cost that much more to make them in the US with an almost fully automated factory and an analytical laboratory for testing. Very little human labor required, which can be done using clean suits.
The bottles themselves could become contaminated especially if they are made overseas as well. But there too, a modern-day filling line could sanitize them in-line. And I would think there is some kind of preservative in them - mostly because of potential contamination by the consumer.
