Abstract
A lens cover includes a housing defining an optical aperture. A pair of opposed lens cover blades are each pivotally mounted to the housing at a common pivot point. A biasing member biases the blades apart from one another about the pivot point to uncover the optical aperture in an open position. A pair of magnetic members is included, each magnetic member being mounted to a respective one of the blades to bias the blades together to cover the optical aperture in a closed position.
