Bottom line: No FDA‑approved or OTC eye drops prevent AMD, and there is no solid evidence that ordinary lubricating or allergy drops, multivitamins or common OTC pain medicines cause AMD. Observational studies have linked prescription vasodilators, oral beta‑blockers and high‑dose anticholinergic drugs to modest increases in AMD risk, while NSAIDs may even be protective

AMD is a progressive disease it has 3 stages- early, intermediate and advanced.
With regular eye exams it is detected, but without eyes exams, it goes unnoticed until you cant see well. It is not caused by an incident or eye drops. The causes of AMD are multi-factorial- genetics, age, smoking, obesity, etc. There is no one reason or causation.
