I have trouble deciding between bifocals and progressives, so each time I get new glasses, I alternate. This year, it was time to give progressives another try. This time, I finally tried Varilux™ progressives. I may never go back. Still not perfect, but they fit nearly every situation comfortably so I don't have to take them off frequently. And I had trifocals only once and really should have either trifocals or progressives for driving a car so I can see the dashboard.
