wt is thinner - glass or plastic?
transition oso got hybrid lens?
glass usually comes in 1.5/1.7/1.8/1.9 index
average is glass thinner but for your degree not much of a
diff(you won't be able to tell)
hybrid is only for sunactives(its just another model for the
lenses)
what i've seen for transitions so far
1.5
1.5+multicoat
1.6+multicoat
1.6+multicoat+impact resistance(polycarbonate material)
1.67 multicoat
