According to an embodiment, the pH of a diisocyanate composition and a diamine hydrochloride composition used in the preparation of an optical lens is adjusted to a specific range, whereby it is possible to enhance not only the yield and purity of the diisocyanate composition but also the optical characteristics of the final optical lens by suppressing the striae and cloudiness. Specifically, according to the process of the embodiment, the amount of an aqueous hydrochloric acid solution introduced to the reaction may be adjusted to control the pH of the diisocyanate composition to a desired range, thereby enhancing the yield and purity. Accordingly, the process for preparing a diisocyanate composition according to the embodiment can be applied to the preparation of a plastic optical lens of high quality.

An example device includes a fluid lens, where the fluid lens includes a membrane, a substrate, and a fluid located within an enclosure formed at least in part by the membrane and the substrate. The membrane may be an elastic membrane. The fluid may include an amount of an additive that is effective to appreciably reduce bubble formation within the fluid, such as when a negative pressure is applied to the fluid. In some examples, the additive may include particles, such as nanoparticles. The additive may include a thixotropic agent that helps to impart an appreciable thixotropic property to the fluid. Various other methods, systems, and computer-readable media are also disclosed.

A biomedical device is disclosed which is a polymerization product of a mixture comprising (a) one or more difunctional isocyanates; (b) one or more polyalcohols; (c) one or more hydroxy-terminated polysiloxane prepolymers; and (d) one or more polyoxazoline polyols having a weight average molecular weight of equal to or greater than about 1000 Daltons.
