What is an anti-refractive (anti-reflective) coating?
Antireflective (AR) coatings improves both the aesthetics of eyeglass lenses and the visual acuity through the lenses. AR coatings reduce the number of reflections between the front and the back of lenses reducing the “coke bottle” effect of large minus lenses and reduce halo effects around bright lights and ghost images while driving at night. AR coatings also reduce external reflections from the lenses making your eyes appear more natural and especially in the case of sunglasses reduces the back reflections produced from light entering from behind the lens.
