When cleaning glasses, how do I use the Microfiber Glasses Cleaning Cloth correctly to avoid scratching the lenses?

Microfiber Glasses Cleaning Cloth is an ideal tool for cleaning glasses due to its softness and efficient cleaning ability. However, if used improperly, it can still cause scratches or damage to the lenses. The following are detailed correct usage methods and precautions to help you clean your glasses safely and effectively while protecting the lens surface.

Preparation before cleaning
Check the lens surface
Before using the cleaning cloth, gently touch the lens surface with your naked eyes or fingers to check if there is obvious dust, sand or other hard particles.
If there are larger particles on the lens, direct wiping may cause scratches. Therefore, these particles must be removed first.
Removing particles
Use an air blower: You can use an air blower (such as a lens air blower) to blow away dust or particles on the lens surface. This is the safest method and avoid direct contact with the lens.
Rinse with running water: If you don’t have an air blower, you can gently rinse the lens with warm water to remove dust and particles on the surface.
Avoid wiping directly with your hands: Grease or hard particles on your hands may further contaminate the lens.
Correct use of microfiber glasses cleaning cloth
Make sure the cleaning cloth is clean
Before use, make sure the microfiber glasses cleaning cloth itself is clean. If dust or oil is attached to the cleaning cloth, it may cause secondary contamination to the lens.
If the cleaning cloth has been used, it is recommended to wash and dry it before use.
Gently wipe
Spread the cleaning cloth flat on the surface of the lens, press lightly with your fingers and wipe in a circular motion or straight line.
Avoid excessive force or rapid rubbing to avoid damage to the lens coating (such as anti-reflective coating, anti-blue light coating).
Don't fold into sharp corners
Avoid folding the cleaning cloth into sharp edges, as the sharp parts may cause fine scratches on the surface of the lens.
Use with cleaning fluid (optional)

If there are stubborn stains on the lens (such as fingerprints, oil stains), you can use it with a special glasses cleaning fluid.
Spray a small amount of cleaning fluid on the lens instead of directly on the cleaning cloth.
Gently wipe with a cleaning cloth until the lens is completely dry.
Never use cleaners containing alcohol, ammonia or other corrosive ingredients, as these chemicals may damage the lens coating.
Precautions and common mistakes
Avoid dry wiping
If there is dust or particles on the surface of the lens, wiping it directly with a dry cleaning cloth may cause scratches. Always remove the particles before wiping.
Do not use ordinary cloth as a substitute
Ordinary cloths (such as paper towels, clothes or towels) may contain rough fibers that can easily scratch the surface of the lens. Always use a special microfiber glasses cleaning cloth.
Avoid frequent cleaning
Cleaning the lenses too frequently may accelerate the wear of the coating. Clean the lenses only when they are visibly dirty.
Do not mix with other items
The cleaning cloth should be stored separately and avoid contact with hard objects such as keys and coins to prevent the cleaning cloth from being contaminated with particles.
Cleaning suggestions for special lenses
Anti-blue light lenses
Anti-blue light lenses usually have special coatings. Be extra careful when cleaning and avoid using cleaning agents containing abrasive ingredients.
Polarized lenses
The surface of polarized lenses is more sensitive. It is recommended to use only microfiber glasses cleaning cloths and special cleaning solutions for cleaning.
Coated lenses
Coated lenses can easily lose their luster or develop spots due to improper cleaning. Be gentle when cleaning and avoid using corrosive detergents.
Maintenance and care of cleaning cloths
Regular cleaning: Microfiber eyeglass cleaning cloths need to be cleaned regularly to maintain their cleaning ability. They can be hand washed with warm water and neutral detergent, and avoid using a washing machine or dryer.
Dry thoroughly: After cleaning, let the cleaning cloth dry naturally, avoiding direct sunlight or high temperature drying.
Store separately: Cleaning cloths should be stored in a clean bag or box to avoid contact with dust or other contaminants.

Scientific cleaning habits can not only extend the life of glasses, but also protect your vision health.
