Abstract
A device comprises a surface that is a hydrogel having a targeted mesh size that permits a low-speed friction coefficient near or lower that that typically reported for cartilage of 0.01 to 0.02, a transition. The device can be a contact lens to sit on the cornea where, during a blink, eyelid slides past the eye surface at about 100 mm s. The hydrodynamic lubrication of the hydrogel of the device separates the contact lens surface from the surfaces of the tarsal conjunctiva and marginal conjunctiva of the eyelid. Other devices that can comprise the hydrogel of a targeted mesh size are those that can contact cartilage of articulating joints.
