Which of the following should be considered when using face shields or goggles?

Wearing face shields or goggles that are free of scratches is crucial for maintaining clear visibility while riding. Scratches can distort vision and create blind spots, potentially leading to hazardous situations on the road. Clear, unobstructed vision is essential for a safe riding experience, allowing riders to effectively perceive their environment, react to obstacles, and make critical decisions quickly.

Considering other factors like wearing them over regular glasses, modifying them for a better fit, or using them only during the day involves different aspects of comfort and usability. However, regardless of those aspects, if the face shields or goggles are scratched, they compromise safety first and foremost. Thus, ensuring that the protective gear is scratch-free is a foundational safety consideration that must be prioritized.
