The invention is related to a hydrated silicone hydrogel contact lens having a layered structural configuration: a lower water content silicone hydrogel core (or bulk material) completely covered with a layer of a higher water content hydrogel totally or substantially free of silicone. A hydrated silicone hydrogel contact lens of the invention possesses high oxygen permeability for maintaining the corneal health and a soft, water-rich, lubricious surface for wearing comfort.

Described herein are anti-microbial and UV-protective biological devices and extracts produced therefrom. The biological devices include microbial cells transformed with a DNA construct containing genes for producing proteins such as, for example, zinc-related protein/oxidase, silicatein, silaffin, and alcohol dehydrogenase. In some instances, the biological devices also include a gene for lipase. Methods for producing and using the devices are also described herein. Finally, compositions and methods for using the devices and extracts to kill microbial species or prevent microbial growth and to reduce or prevent UV-induced damage or exposure to materials, items, plants, and human and animal subjects are described herein. Also disclosed are biological devices producing polyactive carbohydrates and carbo sugars, as well as compositions and articles incorporating both extracts from these devices and the anti-microbial and UV-protective extracts.
