text: I have been wearing the 3M version of these for years and love them. I thought I would try this MFG and I wasn't happy with the product so I returned them (clear and gray). They are OK, and by all means are a good value, they just don't have the same quality feel of the 3M product. The hinges are stiffer and they don't have as good of clarity. For most folks these may be perfectly fine, especially for kids.
