Explanation:

Personal protective goggles are meant to protect the eyes from hazards like chemicals, debris, and splashes. They need to cover both eyes and be securely fastened to be effective. Loose placement around the neck or on the forehead won't offer protection, and they are essential in many experiments to safeguard the eyes.

Answer:

They should be covering both eyes and pulled tight.
