What is a recommended way to prevent contamination when administering eye drops?

Using small bottles for administering eye drops can be a recommended way to prevent contamination. Smaller bottles tend to ensure that the solution remains uncontaminated as they are used and can be disposed of once empty, reducing the risk of exposure to environmental pathogens.

Additionally, they often allow for easier control over the amount dispensed, which can help minimize the chances of touching the dropper tip to the eye, eyelids, or surrounding structures, which can introduce contaminants.

While other options may have merits, using small bottles is particularly effective in maintaining sterility and managing dosages without needing to use additional equipment that might carry a risk of contamination.
