Hi@sjs1,

Whether make search on following website ?
FDA U.S. FOOD & DRUG
https://www.fda.gov/drugs
I have made a search on the eye drops which I suspect causing the vision problem on my left-eye

Search made on : name of the eye drops, manufacturer and its country of origin (Japan)
But no search result found.

I'm very cautious on eye drops. I have been using another eye drop of this manufacturer for >10 year without problem, twice per day. It keeps my eyes wet and comfortable.
