Another significant stage earned by the Opti-fold team. We're making this a reality. The iCAN International Invention Innovation Competition in Canada was Opti-fold's first competition where the technical aspects of the 'product' was judged. Explaining how the invention worked was our focus.
The TECHNICAL reason why Opti-fold works is this:
When the curved eyelid skin is subjected to sustained periods of controlled stretching and bending, mechanotransduction pathways are activated; by which cells convert mechanical stimulus into electrochemical activity, which encourage the process of cell division called mitosis, and promote collagen synthesis. This leads to cell growth as well as to the formation of new cells. As a result, the topographical skin surface area increases and it develops at a higher growth rate than the underlying biological layers. When this mismatch in compressive strain rises to critical values, and the to-be-made 'double eyelid crease' originates and extends from the inner corner of the eye (epicanthal crease) and following dominant facial tension lines, the initially flat surface of the skin will become unstable and will fold onto itself as the eyelid opens.
In reference to the BELOW diagram, when you're only using the fTape, the curve at #2 is reinforced, but the upper skin at #3 will not be pulled downwards to make the curve at #4 reinforced. When the two tapes are used in unison, it provides the sustained controlled stretching and bending of the upper eyelid skin which activates changes of the skin.
