Effect of Soft Contact Lenses with a Hydrophilic Polymer on the Contrast Sensitivity Function

Anisotropic sol–gel transition and morphological aspects of a hierarchical network of nematic gel and a superimposed photopolymer

“…We realised that these systems may be viewed as a parallel amalgamation to the double or inter-penetrating networks, well-studied in hydrogels and polymer gel systems. [26][27][28][29][30][31][32][33][34] Such networks, especially in hydrogels, can be formed either by utilizing polymers or low molecular weight organogels. For instance, two orders of magnitude higher (from 0.2 MPa to 25 MPa) sustainability to compression stress was observed in a double network hydrogel system compared to its single network counterpart, 25 even when the water content was nearly 90%.…”

“…[26][27][28] These and such observations have opened up possibilities to deploy them in drug delivery systems, tissue engineering, biosensors, soft contact lens, etc. [29][30][31][32][33] Extension of competing network strategy studies to an anisotropic environment will add another dimension to the knowledge base on two networks imposed on a single host.…”
