Bifocal Lenses

If you want to be able to see in the distance and close up without having to keep taking your glasses on and off, you could try Bifocal lenses. Bifocals give you good, stable vision for both far away and your natural reading distance but they may not be perfect for computer use and other intermediate vision tasks as unlike varifocals they do not have a specific area on the lens dedicated to this focal length. This problem can be solved by having an additional pair of glasses for intermediate vision. Bifocal lenses have a physical line on the lens dividing the distance and reading areas which some people do not like both in terms of appearance and getting up and down steps.
