    Abstract: The method consists in hydrolysing an initial volume Vse of a precursor material comprising at least one polyalkoxysilane with a quantity of water such that x ⁢ ⁢ H 2 ⁢ O x ⁢ ⁢ Si >= 10 , ⁢ and where x H 2 0 and x Si represent the number of moles of H 2 0 and Si present, respectively, the concentration of the hydrolysate up to a volume substantially equal to the initial volume Vsi, leaving the concentrated hydrolysate until segregation into an aqueous phase and an organo-silicon phase, and recovery of the organo-silicon phase. A product can be obtained which comprises an organo-silicon sol comprising silicon species T 1 , T 2 , and T 3 , wherein the molar fraction of species T 2 is equal or greater than 50%, comprising a condensation rate equal to or greater than 0.65, and further defined as lacking water, as determined by analyzing a sample of said organo-silicon sol by 1 H NMR and observing the absence of peak corresponding to water.

    Abstract: An ophthalmic lens comprises a transparent substrate and electro-optical means integrated with the substrate to perform an optical function in response to an electrical stimulus. The ophthalmic lens further comprises at least one photovoltaic cell integrated with the substrate to power the electro-optical means in response to an incident light, and optionally also a control circuit for controlling the electrical voltage. The photovoltaic cell may be incorporated in an opaque element occupying a small fraction of the area of the lens. Alternatively, the photovoltaic cell may be transparent and may cover at least a portion of the area of the lens.
