Grease, oil and water repellent. New TeflonŽ EasyCare shrugs off smudges more easily than before, because of the unique chemical composition of its top coating; a hydrophobic and oleophobic formulation.
After 1 rub with a tissue, 90% of grease is removed from a TeflonŽ EasyCare lens - less than 50% from a hardcoated lens.
A hardcoated lens has seven times more haze from leftover grease than a TeflonŽ EasyCare coated lens.
Many AR coatings are easy to clean at the time of purchase, but often their hydrophobic and oleophobic topcoats fail under the strain of daily cleaning and exposure to moisture and UV rays. TeflonŽ EasyCare significantly outlasts conventional AR lenses. That’s the quality and performance you and your customers can expect from TeflonŽ.
Contact angle showing beading of water droplets on lens surface. Easy clean coatings create a high contact
angle as illustrated above. This is maintained with TeflonŽ EasyCare but not with conventional ‘easy clean’ coatings.
TeflonŽ EasyCare eliminates more reflective glare than conventional AR lenses. Here’s how:
- The luminous reflex colour intensity of TeflonŽ EasyCare is more than 50% lower than conventional AR lenses.
- Ghost images and internal reflections are now more than two times less visible than conventional AR lenses.
To combat the damage daily wear can do to lenses, TeflonŽ EasyCare offers the toughest scratch resistance, surpassing conventional AR lenses in controlled abrasion tests.
