Abstract: Various embodiments of the present technology generally relate to treatment for dry eyes. More specifically, some embodiments of the present technology relate to eyeglass frames for treatment of dry eye syndrome and corresponding three-dimensional printing systems and methods. In some embodiments an eyewear apparatus includes a frame with a seal configured to engage with the skin of the wearer around a majority of the perimeter of an interior portion of the front of the frame sufficient to keep the humidity around the eye high enough to provide relief from symptoms of dry eye syndrome.

Abstract: A system for exposing a cell culture to a fluid shear force imparted by a fluid flow is provided. Specifically, various embodiments of the present invention provide flow chambers defining channels for retaining a cell culture in the fluid flow wherein the flow chambers may be removably disposed within a bioreactor system such that the flow chambers may be removed and/or replaced without disturbing the cell cultures retained therein or disposed elsewhere within the bioreactor system. The flow chambers are composed of a transparent material such that a user of the system may observe the development of the cell culture retained within the chamber as the cell culture is imposed to a fluid shear stress imparted by the fluid flow.
