The Albion Progressive Clear Reader is such a fabulous new style. The frame is packed with style. For those who can adjust to progressives this style is for you. The 1.50 and 2.0 reading powers progress up the lens to .5. The 2.50 reading power progresses up the lens to 1.0. This means that there is a fluid transition from reading to distance with computer and phone viewing in the middle. Many people love the progressives. They are hundreds of dollars at the optometrist, so many people have saved a lot of money. If you try them and do not adapt to them, you can always return them to us. Frame Measurements: 5 3/8" x 1 7/8" (temple to temple x height of lens)
