In this article, the author discusses the difficulty in processing Trivex lens materials. According to the author, laboratory managers often had to guess as to which process setting they used based on the specific type of equipment they had. He offers some strategies for blocking, generating, fining and polishing Trivex lens materials. He also explains the importance of the edging step in the process.
