Abstract
A tear shaping structure or structures that shape a tear film of an eye thereby enabling a desired refractive effect. The tear shaping structure includes a supporting structure supporting a plurality of capillary action members, the capillary action members being spaced apart and arranged in such a way as to create a desired refractive lens effect by shaping the tear film of an eye.

A shaping structure to shape a tear film of an eye, comprising:
- a supporting structure having a plurality of independent and separate liquid shaping capillary action structures that are structured to interact with a liquid film by capillary action, the liquid shaping capillary action structures being spaced apart thereby defining a plurality of independent and separate circumscribed passages therebetween, the plurality of independent and separate circumscribed passages each being surrounded by and circumferentially enclosed by the liquid shaping capillary action structures whereby fluid communication through each of the passages of the shaping structure exists and the liquid shaping capillary action structures being arranged in such a way as to create a desired refractive lens effect by shaping the liquid film proximate each of the plurality of independent and separate passages when the liquid shaping capillary action structures are immersed in the tear film.
