5. Operating Instructions

5.1 Using the Lenses

• During Operations: When performing tasks such as welding vicinity work, metal melting, or furnace viewing, ensure the flip-up lenses are in the down position, covering your eyes.
• Intermittent Tasks: For tasks requiring clear, unshaded vision, gently flip the lenses up. The spring-loaded mechanism will hold them in the raised position.
• Environmental Awareness: Always be aware of your surroundings. The Shade 3 tint reduces brightness, which may affect perception in dimly lit areas.

6. Maintenance and Care

6.1 Cleaning

• Clean lenses regularly with a soft, lint-free cloth and a mild soap and water solution.
• Avoid abrasive cleaners, solvents, or paper towels, as these can scratch or damage the lens coating.
• Rinse thoroughly with clean water and air dry or gently blot with a clean, soft cloth.

6.2 Storage

• Store the safety glasses in a clean, dry place away from direct sunlight and extreme temperatures.
• Use a protective case to prevent scratches and damage when not in use.

7. Troubleshooting

• Lenses not fitting securely: Ensure the clip is properly aligned with the bridge of your primary eyewear. Adjust position until a firm grip is achieved. If the clip is damaged, discontinue use.
• Reduced visibility: Check lenses for dirt, smudges, or scratches. Clean as per Section 6.1. If lenses are heavily scratched or pitted, replace the unit.
• Discomfort: Ensure the clip is not pinching or applying excessive pressure to your primary eyewear or nose bridge. Adjust position for comfort.
