They come they go
These glasses are great for just kicking around and relaxing. I bought them for when I am skiing and want to hike with glasses instead of goggles on. They work well for this and keep the sun out of my eyes. They are very affordable but are certainly not the highest quality pair of glasses. The lenses are not anything special though they are nice for the price, and the hinges do loosen up rather quickly. Other than that they work great as a pair of cheap glasses, which I tend to break or lose often.
