What is the function of an Rigid Eye Shield in trauma care?

The function of a Rigid Eye Shield in trauma care is to protect the eye from further injury. When a patient has sustained an eye injury, it is crucial to prevent any additional trauma that could exacerbate the situation or complicate recovery. The rigid structure of the eye shield provides a physical barrier, safeguarding the affected eye from external impacts, contaminants, and unnecessary movement that could disrupt the healing process.

Using an eye shield is particularly important in cases where there's potential for penetration or foreign objects, as it not only protects the eye itself but also helps to stabilize any associated injuries. This protective measure is a key component of first aid and trauma care, allowing for safe transport to a medical facility for further evaluation and treatment.

The other options, such as applying pressure, preventing eye movement, or providing hydration, are not the primary functions of a rigid eye shield and may not address the critical need for protection specifically in the context of trauma care.
