Hydrogels have been used as the primary material in the fabrication of contact lenses.

A hydrogel is a cross-linked hydrophilic polymer network filled with liquid which behaves like both solid and liquid under applied stress.

When the mechanical stress is released, the hydrogel recovers as it supports diffusion of the liquid through the pores in the solid meshwork.
