Of all the choices for these sunglasses this tint is the lightest and mose useful.  Its an amber tint.  The other tint choices are VERY dark and are too dark for me except on the brightest days.  The amber tint is very nice for any light level that requires sunglasses.

They are called unbreakable but they seem like they would be easy to snap to me.  The nose piece occasionally comes off of one pair that I have but I think if I epoxy it on it will be fine.

These sunglasses are VERY comfortable and look good too.  I recommend them to anyone wanting a low cost pair of glasses.
