The DUCO DC5206 glasses are designed for a comfortable fit for most face shapes. Gently unfold the temples and place the glasses on your face.

4. Operating Instructions

4.1 Wearing the Glasses

Place the glasses on your face, ensuring the nose pads rest comfortably on your nose bridge and the temple arms extend over your ears without causing pressure. The lenses should be centered over your eyes.

4.2 Optimal Use

For best results, wear your DUCO DC5206 blue light blocking glasses during prolonged exposure to digital screens, such as computers, laptops, tablets, smartphones, and televisions. They are also beneficial when reading under fluorescent lighting.

Benefits of consistent use include:

• Minimization of headaches associated with digital screen use.
• Improved sleep quality by reducing blue light exposure before bedtime.

5. Maintenance and Care

5.1 Cleaning Instructions

1. Rinse the lenses under lukewarm water to remove any loose dust or debris.
2. Apply a small drop of mild dish soap to each lens.
3. Gently rub the lenses and frame with your fingertips.
4. Rinse thoroughly with lukewarm water to remove all soap residue.
5. Dry the lenses and frame with a clean, soft microfiber cloth. Avoid using paper towels or rough fabrics, as these can scratch the lenses.

5.2 Storage

When not in use, always store your DUCO DC5206 glasses in the provided protective case. This will prevent scratches and damage from accidental drops or pressure.

5.3 Precautions

• Avoid exposing the glasses to extreme temperatures (e.g., leaving them in a hot car).
• Do not use harsh chemicals, abrasive cleaners, or alcohol-based solutions on the lenses or frame.
• Do not place the glasses face down on hard surfaces.

6. Troubleshooting

Common Issues and Solutions:

• Blurry Vision: Ensure lenses are clean. Follow cleaning instructions in Section 5.1.
• Discomfort or Poor Fit: The TR90 frame is flexible. For minor adjustments, gently bend the temple arms. For significant adjustments, consult a professional optician.
• Persistent Eye Strain: While these glasses help reduce eye strain, prolonged screen time without breaks can still cause discomfort. Remember to take regular breaks (e.g., the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds). If symptoms persist, consult an eye care professional.
