I bought these for my first summit of Mt Rainier and used them on a couple more mountains in Ecuador. I bought a different pair and had these as a backup, but never used them again. There is a light scratch on the right lense that I'm not sure is repairable. However, they are definitely usable and the lense is replaceable.
