An improvised eye shield may be made from which material?

• A. Glass bottle
• B. Styrofoam or a plastic cup
• C. Metal lid
• D. Ceramic plate

Answer: (B)

The main idea here is choosing an improvised eye shield that protects the eye safely using materials you’re likely to have on hand in a field setting. The best option is a soft, lightweight material that can be shaped to fit the face and won’t introduce sharp edges or heavy pressure.

A Styrofoam or plastic cup fits that need well. It’s gentle against the skin, easy to mold to the contour of the face, and lightweight so it won’t press on the eye. You can trim it to fit and then secure it with tape or a bandage, creating a protective cover over the eye without adding risk. These materials are widely available in field kits and are easy to sanitize and re-secure as needed.

In contrast, a glass bottle is risky because it can crack or break, leaving sharp shards and a rigid surface that could press on or injure the eye. A metal lid often has sharp edges and is relatively rigid, which can scratch or apply pressure. A ceramic plate is heavy, brittle, and can shatter into sharp fragments, making it unsafe for use over the eye.

So, the safest and most practical improvised eye shield in the field is a soft, moldable option like a Styrofoam or plastic cup.
