An apparatus for applying a primary coating and a secondary coating to an optical fiber is disclosed. The apparatus includes at least one pressurized source of primary coating, a first primary reservoir for applying a first layer of the primary coating to the optical fiber, a first primary die including a first primary land configured to size the first layer of the primary coating, a second primary reservoir for applying a second layer of the primary coating to the optical fiber, a second primary die including a second primary land, a pressurized source of the secondary coating, a secondary reservoir for applying a layer of the secondary coating to the optical fiber, and a secondary die including a secondary land configured to size the layer of the secondary coating.

Methods and apparatuses estimate and control optical fiber primary coating diameter for wet-on-wet optical fiber manufacturing. The primary coating diameter for a particular length of optical fiber is calculated based upon a measurement of the weight of primary and/or secondary coating material consumed during optical fiber manufacturing. Control of the primary coating diameter is effected by a coating controller which can increase or decrease the primary coating diameter through control of glass temperature, coating viscosity and/or other parameters during wet-on-wet fiber manufacture.

The invention is related to a disposable contact lens comprising a top coating which is made of a hydrophilic polymeric material including dangling hydrophilic polymer chains covalently linked to the hydrophilic polymeric material through oligo-caprolactone linkages susceptible to enzymatic degradation in the eyes. The top coating is stable to lens processing/storage and confers lubricity to the lens. However, it slowly is degraded during the lens wear due to the action of enzymes (e.g., Lipase) in tear film. The loss in lubricity will be experienced as a drop in comfort for the lens wearer and thereby serves as the built-in compliance features of the disposable contact lens.

The instant invention pertains to a method for producing contact lenses with improved oxidative stability of Carotenoids in the contact lens. The method of the invention involves adding a vitamine E material into a contact lens in an amount sufficient to reduce oxidative degradation of Carotenoids in the lens by at least about 30% in comparison with an identical contact lens without the vitamin E material.

Described herein are polyphenylene fibers. The polyphenylene fibers have one or more polyphenylene polymers. The polyphenylene fibers can further include one or more poly(aryl ether sulfone) polymers. In some embodiments, the polyphenylene fibers can have an average diameter that is less than about 1 micron. The polyphenylene fibers can have desirable mechanical properties. Also described herein are methods for forming polyphenylene fibers. In some embodiments, the fibers can be fabricated using specifically engineered polymer solutions in conjunctions with adapted force spinning techniques.
