Computer Bifocals

I am using bifocal glasses. Can I go for progressive lenses so that I can clearly see the computer monitor?

Now I have a separate glass for computer. I understand that with progressive lenses I can see objects at all distances (near, middle and far). If this is correct how is this achieved?

Yes, it is true that progressive lenses give you all three ranges of vision. However, the intermediate area that would typically be used for computers is not that wide of an area on your progressive lenses. If you have separate glasses for the computer, I would suggest you still use them if the prescription is still the same because the entire lenses would have the proper prescription instead of just a small amount of the lens. The progressive lenses are still great lenses if you have to look at all three ranges at the same time.
