Varifocals are the closest thing to natural vision that you can get in glasses. There’s no line in the middle, so they don't look old-fashioned like bifocals.
It also depends on the varifocal lens that you get. With all varifocals there’s a certain amount of soft-focus. This is where the vision at the sides of the lens isn't as pin-sharp as the vision in the centre. The cheaper, old-fashioned varifocals usualy have a lot of soft-focus in them. That’s why people never really got on well with them a few years ago.
Now, however, as with everything technology has made some great advances. Modern day varifocals usualy have a lot less soft focus, so they are much easier to get on with. I would suggest that you do pay a tiny extra for the lenses. Some opticians are now offering free varifocals lenses with frames. Don't go for these, as they are usualy the old-fashioned type.
The way I see it, you should always spend more money on the lenses than the frame, as the lenses are what is going to be in front of your eyes for the next couple of years. Some good brands of varifocal would be Essilor, Zeiss, Sola One and Seiko.
And if you are unsure, ask in your opticians to talk to the dispensing optician. We are trained in all the different lens types and measurements, so you will get the best advice.
I hope this helps! 
Answer:
your speaking about no-line progressives right? cause if you are then they are pretty good in that you only have to use one pair of glasses. As long as you can see clearly, (the right Rx and all). I've heard bifocals with lines are annoying in that in doesn't let you shift proper between near, far, and middle distance vision.
Answer:
If you need glasses for distance and reading they’re easier to wear than bifocals. Again it is a matter of what suits you.
