Can you use 0.9 NaCl for eyewash?

0.9% NaCl (normal saline) can be used for eyewash in certain situations, as it is isotonic and generally safe for irrigation of the eyes. However, it is essential to ensure that the solution is sterile and free from contaminants. For eye injuries or more serious conditions, it's best to use a specifically formulated eyewash solution or seek medical attention. Always follow medical guidelines and protocols for eye care.
