This site has a pretty good explanation of the different types of progressive lenses:
http://www.allaboutvision.com/lenses/progressives.htm
Many different progressive lenses are on the market today. The differences among the lenses are mainly in the width of the central corridor of optimum vision. Different areas of the corridor are expanded depending on the function that each particular lens is designed for. Some progressives that are made for a great deal of computer use, for example, have a wider intermediate zone. Others have a larger reading portion. Your eyecare practitioner is in the best position to evaluate which lens style will work best for you.
I had the same problem with the first pair of progressive lenses I tried, the field at the bottom was to narrow, I had to upgrade to a higher costing lense to get the wider field at the bottom.
