these are mostly plastic, which make them great for outdoor work because they will function a bit like (but not actually like) eye protection. too flimsy to really protect the eyes.because they are mostly plastic, the wrap around design makes everything that you view look warped, so, not at all good reading classes or computer glasses. just good for a minute or two day wear.
bought these after cataract surgery to restore my close-up/fine-print vision. feather-light, good-looking and comfortable, but not so durable; first pair broke after 2 months, even with the hard-shell case i bought to replace the plastic boxes that come with the glasses. glad they come in packs of 4.
