Final answer:
The best action for a corneal abrasion is to stop wearing contact lenses and discard the old ones to allow for healing and prevent infection.
Step-by-step explanation:
The recommended action for a corneal abrasion, which is characterized as a scraped area of the corneal surface accompanied by a loss of superficial tissue (epithelium), is to cease contact lens wear and discard old contacts. Continuing to wear contact lenses could inhibit healing or introduce bacteria that could lead to infection. Therefore, it is crucial to allow the eye to heal without further irritation, and due to the risk of contaminating the corneal abrasion with bacteria from the contacts, they should be discarded. In most cases, corneal abrasions do not require immediate surgical intervention, but it's important to seek medical advice to rule out more serious damage and to get appropriate treatment.
