I just got cataract surgery on both eyes and my Favorite Persol Sunglasses were no longer useful! With Tajima's help (they sent a postage-paid label), I was able to send them to Tajima Direct and get my no longer useful prescription sun lenses replaced with what I feel to be very high-quality Grey Polarized lenses that have very good back surface anti-reflective treatment. I was just starting a 2-week road trip and they offered to mail them to me in Santa Fe. My Surgery was planned to have my left eye for Near and the right eye for Distance...with the high-quality lenses, my adaptation while driving has been easy! 🙏
