Important usage and maintenance information

This guide provides essential instructions for the care and handling of your Generic 2283F7E0 night vision glasses. Following these guidelines will help prevent damage to the lenses and deformation of the frame.

Handling and wearing

To maintain the structural integrity of your glasses, please adhere to the following handling practices:

• Use both hands: Always use both hands when putting on or taking off your glasses. Using only one hand can easily deform the frame.
• Avoid hard objects: Do not place your glasses in contact with hard objects such as keys, pens, or mobile phones.

Cleaning and care

Proper cleaning is vital to prevent scratches and damage to the lens surface:

• Use the provided cloth: Use the spectacle cloth included in the accessories to wipe away dust, dirt, stains, grease, or fingerprints.
• Avoid chemicals: Never use chemical products or your fingernails to remove marks or dirt from the lenses.
• Handling sand: If fine sand particles are on the lenses, rinse them with water and dry them using a cloth or paper designed for glasses.

Storage and environmental protection

Protect your glasses from environmental factors and improper storage:

• Storage: When not in use, place the glasses in their case or on a table with the lenses facing upwards. Ensure the lenses do not touch the table surface to prevent wear and tear.
• Avoid heat and light: Do not leave the lenses in a heated room or in direct sunlight for long periods, as this can cause discoloration or deformation.
• Avoid interference: Do not expose the lenses to liquids, electric currents, or magnetic fields for extended periods.

Troubleshooting

If the lenses feel loose, check if the issue is caused by a loose screw. If so, use a screwdriver to lightly tighten the screw in a clockwise direction.
