Joe -- I got new billiards-spex a few years ago -- the noze support iz low down so that the spex sit very hi -- and they are rimless, titanium.
Anyhow, theze spex are the best i hav ever played with -- but the main thing iz that i wear them all day every day at home and outside and when i am driving -- but i dont need them for reading, i am near-sighted. But everyone laughs at me koz they look funny (gulp)(or it might be my fat head).

In the past the main problem with billiards-spex haz been that they aint much good for say one hour after u put them on -- the balls dont look round -- not a problem no more.
