They are characterised by a gradual increase of lens power, usually between 15 and 20 mm with a final addition power between 1.00 to 2.50, which is added on to the wearers other sight corrections. The levels starts at a minimum - or no additional power at the top of the lens - and reaches a maximum additional power of magnification, at the bottom of the lens.
