The correct order to wash the eye is:

Washing the eye should always be done from the inner corner to the outer corner. This technique is important because it helps prevent infections and minimizes irritation to the eye. The inner corner of the eye is where tears drain, so starting there ensures that any debris or discharge is effectively removed outward.

Using this method also aligns with the natural anatomy of the eye, as it allows any contaminants to flow away from the sensitive inner structures. This practice is particularly important in a healthcare setting, where maintaining hygiene is essential to protect patient health and comfort.

Other options, such as washing from the outer corner to the inner corner or top to bottom, could inadvertently introduce contaminants toward the eye or not effectively remove existing debris. Therefore, the best practice is to always start at the inner corner and move outward to ensure optimal cleanliness and safety during eye care.
