1. An ophthalmic lens, comprising:
a fluid optic body comprising:
a deformable optical membrane configured to extend across an optical axis of an eye,
a sidewall connected to the deformable optical membrane, and
a cavity for containing an optical fluid;
a second optic body spaced a distance apart from the fluid optic body and configured to extend across the optical axis of the eye;
a plurality of struts extending from the sidewall and coupling the fluid optic body to the second optic body, the plurality of struts configured to increase a radius of curvature of the deformable optical membrane under axial compression of the ophthalmic lens; and
a mechanical block configured to limit the increase in the radius of curvature of the deformable optical membrane.
