Query: So far so good

I bought these because I now stare at two computer screens all day at work and felt like my eyes were strained when I got home. I also suffer from migraines. I don't know if these actually make a difference but it seems like it. The glasses themselves are pretty lightweight and flimsy, but they're about what you will expect for the price. As long as you handle them carefully and keep them in the provided case, I don't see there being a problem with longevity. The arms are kinda bendy so you can carefully bend them to fit better behind your ear.
