Perfect for me!
I ordered these as a test not expecting them to fit very well.  What a pleasant surprise.  I have a narrow head and a narrow nose so getting glasses that fit and stay in place is a challenge.  These are perfect.  The spring loaded flexible arms on the glasses allow for a snug but comfortable fit.  I use these for reading and the computer and I find that the rimless design offers maximum visibility and a lightweight feel.  This was a big find for me and will be ordering more in the near future.  Got to have one pair for every room in the house.
