text: I really liked these glasses. However, in less than 7 months, one lens had a crack which continued to get worse, and the other had the start of a crack — this was without ever inter-changing the lens. I shipped the lens to the manufacturer Bushnell since they were still under warranty. According to them this flaw is NOT covered under the warranty. But they will sell me $36 replacement lens if I'd like. A big disappointment!
