The Anatomy of Anti-Reflective Coatings

Modern corrective lenses use CR-39 resin coated with alternating micro-layers of metal oxides. These layers neutralize light reflections through optical interference. Dry rubbing the lens with a shirt cuff drags environmental dust across these thin layers, causing permanent hairline abrasions.

The Correct Cleaning Sequence

Preserving lens transparency requires an effortless daily routine that avoids abrasive contact.

• Step 1: Rinse the lenses under a gentle stream of cold tap water to wash away loose sand and particulate matter.
• Step 2: Apply a drop of neutral ph dish soap between thumb and forefinger to emulsify skin oils along the lens bevel.
• Step 3: Dry the surfaces using a clean, dedicated microfibre cloth without applying hard downward pressure.

Storage Practices

Always store spectacles with the lens convex front pointing upward. When not resting on your face, close the arms and place the unit inside an aluminium-reinforced hard case to protect against direct crushing forces.
