Care Guide for Class Lenses
1. Cleaning
1.1. Daily Cleaning: Clean your lenses with a microfiber cloth and a lens cleaning solution suitable for optical lenses.
1.2. Avoiding Damage:
- Do not use paper towels, tissues, or clothing to clean your lenses as they can scratch the surface.
- Do not use household cleaners, soaps, or detergents which can damage the coating.
2. Handling
2.1. Proper Handling: Always handle your lenses by the edges to avoid fingerprints and smudges.
2.2. Storage: Store your lenses in a clean, dry place when not in use. Use a protective case to prevent scratches and other damage.
3. Usage
3.1. Environmental Factors: It is essential to protect your lenses from various environmental factors to ensure their longevity and performance.
- Extreme Temperatures: Do not expose your lenses to extreme temperatures, such as leaving them in a car on a hot day or in freezing conditions. High heat can cause warping or damage to the lens coatings, while extreme cold can make the lenses more brittle and susceptible to cracking.
- Prolonged Exposure to Direct Sunlight: Continuous exposure to direct sunlight, especially in extreme UV conditions, can degrade the lens material and affect the performance of any UV protection or anti-reflective coatings. Always store your lenses in a protective case when not in use and do not place them in direct sunlight for extended periods.
- Humid Conditions: Humidity can contribute to the buildup of moisture on the lenses, leading to fogging, mould growth, or damage to the coatings. It is important to keep your lenses dry by storing them in a cool, dry place. If your lenses become wet, dry them with a clean, soft cloth designed for lenses before storing them.
Taking these precautions will help maintain the optical clarity, structural integrity, and overall effectiveness of your lenses, ensuring they perform optimally over their intended lifespan.
3.2. Wear: To maintain the condition and effectiveness of your lenses, it is important to wear them properly. Always wear your glasses on your face as intended, ensuring that the frames rest comfortably on your nose and ears. Do not place your glasses on top of your head, as this can stretch the frames, misalign the lenses, and weaken the hinges, leading to a poor fit and potential damage. Additionally, placing glasses on your head can transfer oils and dirt from your hair onto the lenses, reducing visibility and requiring more frequent cleaning. By consistently wearing your glasses correctly, you help preserve their shape, alignment, and functionality, ensuring they provide the best possible vision correction.
Only glasses specifically designed for protection should be used in applications requiring eye safety, such as industrial, construction, or laboratory settings.
3.3. Regular Check-ups: Schedule check-ups with your Eyecare Practitioner every two years to ensure your prescription is up to date and your lenses are in good condition.
4. Repairs and Maintenance
4.1. Professional Adjustments: Do not attempt to adjust or repair your lenses yourself. Seek professional assistance for any adjustments or repairs.
4.2. Inspection for Damage: Regularly inspect your lenses for any signs of damage or wear and contact your eyewear specialist for advice if any issues are found.
5. Safe Disposal: Dispose of lenses and frames in accordance with local regulations for household waste. Do not incinerate lenses, as this may release harmful substances. Packaging materials should be recycled where possible.
By following these guidelines, you can ensure that your Class lenses remain in optimal condition, providing you with the best possible vision and comfort.
A note on Mineral Lenses
Class Optical Manufacturing advises caution in the use of mineral lenses in specific situations due to their inherent characteristics. While mineral lenses provide superior scratch resistance and optical clarity, they are more susceptible to impact-related damage compared to plastic or polycarbonate lenses. For safety reasons, the use of mineral lenses in the following situations is expressly prohibited and will be considered misuse under our terms of service and warranty policy:
- Sports and High-Impact Activities: Mineral lenses are not suitable for sports, high-intensity activities, or any context where the risk of impact or shattering may pose a hazard.
- Protective and Safety Eyewear: For any applications where eye protection is required, such as in industrial, construction, or laboratory settings, impact-resistant materials like polycarbonate are recommended.
- Children’s Eyewear: Due to the higher risk of impact or breakage, mineral lenses are not to be used for children’s eyewear, as they require safer, shatter-resistant materials.
