My glasses are about 4 years old and apparently the newer styles are smaller because most of the overgrazes are not large enough.  These are.  Also my regular glasses are shaded and my old, gray shaded over glasses often made seeing difficult.  This new pair lends a sort of 'golden glow' that brightens what I am viewing while negating the glare.  It's difficult to express what I mean but I recommend them for people who have 'problem reading glasses.'  They come with a fabric case that doesn't amount to a lot but is better than nothing.
