Most scratched lenses are not accidents — they are habits. Thirty seconds of proper care per day keeps coatings clear for the life of the frame.
Never dry-wipe
Dust is abrasive. Wiping a dry lens with a shirttail drags grit across the coating like sandpaper. Rinse or spray first, always.
Spray, circle, done
One mist of coating-safe spray, gentle circles with a clean microfiber cloth, and lenses come back to showroom clarity. Skip household glass cleaners — ammonia lifts coatings.
Respect the case
Lenses down on a desk is how scratches happen while you sleep. A case in every bag beats one perfect case at home.
Wash the cloth
A microfiber cloth loads up with oil and grit over weeks. Machine wash cold, no softener, and it cleans like new.
