I am an Asian Man and want to wear thicker plastic frames not wire frames, and after years of dealing with glasses sliding down my nose and looking directly at the top of the frame instead of the lens, I purchased plastic pads to glue onto the nose pad area. These would fall off and need to be replaced every few weeks. Being a designer that uses 3d printing, I was about to create my own nose pad after years of frustration. Then one day I found Kay Tran's ad. I couldn't believe it! I immediately ordered a pair and I am very satisfied! A simple design solution for a large portion of the population that have similar facial features. Thank you so much!
