AR/AF tempered glass for iPhone

AR tempered glass is standard tempered glass with a special anti-reflective (AR) optical coating added to the surface. While normal glass reflects about 8% to 10% of light—creating that annoying shiny glare under bright lights or sunlight—an AR coating uses ultra-thin layers to cancel out reflections, dropping reflectivity down to around 1% or less

AF tempered glass is standard tempered glass finished with an Anti-Fingerprint (AF) nano-coating on the outer surface
