A variable lens geometry is constructed through a series of spaced vertical curves on and perpendicular to a horizontal curve. Variable geometry is attained by varying the size of the vertical curves along the horizontal curve. In one embodiment, at least one vertical curve more towards the end or temple region of the lens is smaller than at least one vertical curve more towards the interior or bridge region. In another embodiment, the sizes of the vertical curves decrease along the horizontal curve from the bridge portion to the temple portion.
