Traditionally consumers had to choose between scratch-resistant (SR) and anti-reflective (AR) coatings for their lenses, since each has to be on the top layer to be effective. In fact some AR coatings seem to highlight even the tiniest smudges. But the newest coating on the market manages to combine both features: Sold as “Crizal Avance with Scotchgard Protector,” this is a remarkable product that combines anti-reflective, scratch-resistant, and dirt repellent properties all on the same lens.

I had the opportunity to try a pair of Essilor’s Airwear polycarbonate lenses with this new coating. They are less than half the weight of my glass lenses, and their coating really works as advertised.  Ask your eye care provider about Airwear lenses or visit LighterSaferGreener.com for more information.
