Abstract
In one aspect, the invention is directed to a multifocal ophthalmic lens having a first region having first focal properties, and a second region having second focal properties and including a progressive region. The second region may further include, for example, a portion that is a reading region. The second region has two side edges and there are first and second transition regions between the first region and the side edges of the second region. The transition regions each have a width that is less than a selected width. This gives the lens designer more freedom to provide a wider second region without extending into lower left and lower right regions of the lens.
