Great neck pain relief!
I bought these because I love to read in bed and have a neck issue this is exacerbated by holding my neck in a flexed position to read.  This is actually the second pair of these type of glasses that I have bought and I have to say these are WAY better than the first pair (different manufacturers). The first pair had to 'heated and adjusted" because the prisms were not aligned properly and focused the image in my eyes in such a way that it gave me a headache.  After 2 years the ear stem broke off which prompted this purchase.  These are way better built, the prisms are perfectly aligned and I love having the carrying case for travel.  The price is much less than my original pair as well.  If you're looking for this type of reading aid, these are the ones to buy.
