Query: Excellent wrap around framed sunglasses

I really love these safety glasses because they are very inexpensive, fairly durable, come tinted or clear, and my most favorite feature is that there is no frame so they give you an excellent field of view with no obstructions when you are really doing detailed work. They are supposed to have an anti scratch coating but still seem to scratch fairly easily but for the price and features it does not dissuade me from purchasing these glasses. These are the originals that used to be made by AO Safety and are now made by 3M. I have purchased other brands of the same type and the typical problem I have had with the other types is that they break at the nose bridge so don't accept imitations.
