Melanina Sport type from Tsuhan Seikatsu. My wife bought these, but they don't suit her style, so she repurchased a different type. In my subjective opinion, they've only been tried on and are in good condition (though they've been stored at home, so please refrain from purchasing if you are concerned about minor details). For those who know about them, what do you think? They cut harmful rays that cause cataracts and age-related macular degeneration. According to the Japan Spectacles and Optical Instruments Quality Assurance Association, they transmit 82.4% of visible light, so they don't darken and are easy on the eyes. 11,990 yen (tax included) + 660 yen shipping, for a total of 12,050 yen. Size: Width approx. 14cm, Lens diameter 4 x 6.8cm, Temple length 12.5cm Weight: 15g Material: Lens/NXT, Frame/Temples/TR90, TPE Thank you.
