They work but,......
Not sure what "sheerness" means in the revue process for lense cleaners. Anyway, they do work with effort. I think they have too much water compared to alcohol causing them to grab onto glasses lenses. I usually use Ziess lense cleaners but, these were less expensive. Those have enough alcohol so they clean while sliding easily over eyeglass lenses. That's why I gave them four stars. It's not a deal breaker.
Rating: 4 stars
