Got two pairs by selecting frames online. One of these were rimless. They both were progressive lenses. Got excellent bargain, smooth transaction and glasses arrived within two weeks. They fit well and had no complaints. Used one pair more and kept the rimless pair for occasions. I started noticing that the more frequently used pair was losing its clarity. After about a year I noticed that the lenses had visibly changed their color. They had an amber/honey color tinge. I then switched to using the other pair, which looked good although both were bought at the same time. Within three months of usage, even the lenses of the other pair have started showing some tinge and partial loss of clarity. I do not use soaps on these or do not work with chemicals or gasses that may react with these lenses. I mostly work from home. This is the first time I am experiencing that eyeglass lenses can have loss of clarity over time. My experience with Lenscrafters or Warby Parker products is not the same. Their lenses do not have loss of clarity even after years of usage.
