Using shirt sleeves, tissues or household cleaners to wipe glasses can damage expensive lenses and their anti-glare coating. Many people unknowingly cause fine scratches or ruin the coating by using alcohol-based sprays or rough cloths.

To clean glasses safely at home, first wash hands with soap. Rinse the glasses under lukewarm tap water to remove dust. Apply one drop of mild dishwashing liquid on fingertips and gently massage both sides of the lenses, the frame and nose pads for 15-20 seconds. Rinse thoroughly, shake off excess water and pat dry with the microfiber cloth that came with the glasses or a clean cotton cloth.
Never use tissues, towels, newspaper, saliva or glass cleaners like Colin. Store glasses in a hard case when not in use, and wash the microfiber cloth weekly.
This is standard advice from opticians and lens manufacturers, yet lens coating damage remains one of the most common reasons for early replacement. A scratched or peeling coating cannot be repaired, the only fix is a new pair of lenses costing anywhere from Rs 500 to several thousand rupees depending on prescription and coating type. Most Indian households still rely on shirt corners or generic all-purpose sprays because dedicated lens cleaners are not widely stocked. The single most effective habit is the rinse step: running water before wiping removes abrasive particles that cause micro-scratches even with the right cloth.
