This is the official lens for Oakley Latch golf sunglasses. I bought these for golf, but I've only used them twice. I've stopped playing golf, and I've switched the frame to other lenses, so I'm selling the lenses only. Since they are official, how about it for those who want to try the golf model? I've included photos showing the difference in how things look, and they are golf-specific sunglass lenses ^_^ -- Golf, which involves playing outdoors for long periods, is a sport that is affected by various external factors. A round (18 holes) of play takes about 4-5 hours, and you walk 8-10 km on a course with ups and downs. During that time, you are exposed to direct sunlight for a long time, so especially in summer golf, you need to be careful of the effects of ultraviolet rays, heatstroke, and dehydration. The impact of the conditions is directly linked to the performance of the play. OAKLEY's Prizm Golf lenses are dedicated lenses that maintain high-quality performance without losing concentration when used for long periods of golf outdoors. They ensure the brightness of the field of vision regardless of the weather, and accurately convey information that is very important when playing golf, such as the condition of the fairway, rough, and green, and hazards, through the lenses. The lenses themselves have a light pink color overall, and the mirror coating is weak. It's one of the popular lenses that OAKLAY has installed in sports models and lifestyle models. As they are golf-specific lenses, they seem to be very popular, but they are also recommended for those who are looking for a bright lens color for sports other than golf.
