4. Risks of long-term use around eyes
Argyrosis by colloidal silver eye drops
One case describes conjunctival argyrosis (silver deposition in eye tissues) in a person who used colloidal silver eye drops for a long time. The skin color change persisted even after 16 months after discontinuation of use . This emphasizes that long-term use of silver substances in sensitive areas such as eyes poses risks.
