To sustain rich lens hues over time requires a disciplined approach to maintaining, storage, and handling. Consistently use a microfiber cloth engineered for lenses when wiping your lenses. Never use tissues, clothing, or rough materials as they can scratch the surface, leading to loss of vibrancy over time. Prior to buffing, dislodge with a soft puff of air any dust to avoid surface damage during the cleaning process.

Use a lens cleaning solution designed for 乱視 カラコン ワンデー anti-reflective coatings. Avoid use household cleaners, isopropyl alcohol, or strong alkaline cleaners — these can dissolve protective layers that give lenses their color and sharpness. Place 2–3 drops of the approved cleaner onto the cleaning cloth. Do not direct the solution onto the surface — it can penetrate the rim and corrode hinges.

Place your lenses in a rigid protective case when not in use. Soft pouches may seem convenient, but they provide little protection against external force and accidental contact like coins. Position the case in a climate-controlled area out of UV exposure. Chronic exposure to sunlight can degrade pigmentation and diminish hue intensity.

Never leave your lenses on hot surfaces such as dashboards or close to radiators. Thermal stress can distort the lens shape and accelerate coating failure. Moreover, grip your lenses with unsoiled fingers to prevent oils and dirt from accumulating on the coating. If you need to adjust the frame, grip the arms rather than the optical elements.

Finally, check your lenses on a routine basis for visible damage. Should you observe color loss, lines, or haziness that won’t clean off, it may be time to consult a professional. Specific pigment treatments can be recoated, but proactive maintenance is significantly cheaper than restoration. With consistent care, your lenses can preserve brilliant optics and optical performance for a long time.
