Abstract
A spectacle lens is disclosed that includes compound microlenses arranged in a pattern. A compound microlens includes an on-axis microlenslet and an off-axis sub-lenslet located on the on-axis microlenslet. The off-axis sub-lenslet has a different optical functionality than the on-axis microlenslet. By selecting the appropriate compound microlens design, the addition of microlenslets with sub-lenslets around the periphery of the main structure optimizes the spectacle lens for myopia prevention, vertigo prevention, or any other visual related condition.
