I have bifocals, trifocals, and progressives. Last year I flew exclusively with the bifocals. The trifocals are used exclusively in the shop and the progressives are great for driving and shopping.

I talked to my optical guy about all this and he says to quit switching and pick one and go with it full time. He recommends the progressive and says that the new ones are much better than the older ones. Seems my current progressives are the older type and of a lower quality brand. The Varilux and the very expensive Zeiss are reported to be much better.

Because the progressives have a continuously varying lens strength the midrange is great. There is always some spot you can find that is in perfect focus. Great for the supermarket. Sometimes I go into the shop with the progressives on and they are great.

I must admit that it took a long time to get used to the progressives but they are the only ones that I can forget are on. The long and the short is that the next ones will be progressives and of the Varilux brand. Then I will be buying the best Varilux if different qualities are offered.
