MODEL RELEASED. Contact lens storage. Female worker with racks of containers which hold soft contact lenses in a factory storage room. The plastic lenses are used to help correct vision defects such as long- or short-sightedness. The exact shape of the soft lens determines how it will affect the light passing through it. This factory makes batches of lenses of a certain specification. These lenses are stored at the factory until they are sent out to opticians who require them for their patients.
