No, the eyes are not sterile. While the interior of the eye has mechanisms to maintain a clean environment, the surface of the eye, including the eyelids and conjunctiva, is home to a variety of microorganisms, including bacteria. These microorganisms are usually harmless and can even play a role in protecting the eye from infection. However, if the balance is disrupted, it can lead to eye infections.
Using sterile water is ideal if that's all you've got to clean your eyes. It's always better to use saline to clean your eyes out, though.

It might take a while for them to get used to having their eyes done. But if you used an eye-dropper and kept it hidden until just before you put in the drops, you will beable to sneak up on them.
Rinsing eyes with a mild saline solution is safe, as long as the saline is prepared properly. The salt needs to be totally dissolved and it would be better to use a sterile solution available at most pharmacies.

Eyes can be preserved by storing them in a cool, sterile solution such as Optisol-GS or similar media to maintain their viability for transplantation or research purposes. Proper handling, packaging, and refrigeration are important to ensure the preservation of the eyes for as long as possible. Professional medical facilities or eye banks are equipped to handle the preservation of eyes.
No, sterile saline is a solution of salt (sodium chloride) in sterile water, while sterile water is just water that has been sterilized. Sterile saline is commonly used in medical procedures and wound cleaning, while sterile water is used for irrigation and as a diluent for medications.
