1) What led you to purchase this product?
Currently, I am using Z-Parts z-112 (color is BG). The frame is light, soft, yet sturdy and very comfortable. I was thinking of using mirror titanium in a different color for the z-112, but I found the z-87 in a slightly different form and liked it.
2) What led you to use this site?
The one-piece frames (HOYA) that I had been using didn't fit me well (they are bifocal lenses, so the position of my eyes doesn't match up with the lenses for near vision), so I was looking for glasses frames that would fit better. I was looking for a round or oval frame and found the simple and beautiful Z-Parts. I was drawn to the claim that ``The bridge is placed slightly below the center of the lens, achieving a wearing balance that matches the Japanese skeletal structure.''
3) What are your impressions of using this site and the products you purchased ?
Currently, I use z-112 (bifocal) for regular use. When working at close range for long periods of time, I sometimes use the z-91 (bifocal: BG color). Both glasses fit well.
