Progressive lenses correct your vision for near, intermediate and distance.  Progressive glasses are sometimes prescribed to help correct an astigmatism if needed. Please be aware that it takes about a week for you to adjust to them if you haven't worn them before.
The benefit, however, is not having to shuffle your glasses on and off when switching viewing distances. If you spend a lot of time in front of a computer screen or where fine detail work is required, then a second pair of glasses with single vision lenses may be great for you, as well.
Premium Progressive Lenses offer a wider field of vision, and can help progressive wearers adapt to them much faster.
