An assembly for use on a piece of equipment comprising a mobile phone with a camera function, the phone having a light which is integral to the body of the equipment, the phone further including a camera lens capable of taking a photograph of an object, and a phone cover removably attached to the mobile phone. The assembly has a carrier assembly, the carrier assembly has a support and a base, and a carrier member attached to the support, the carrier member being movably and releasably mounted to the support, and the carrier member is movable relative to the base and the phone cover. The carrier member includes at least one lens station mounted on it, the lens station includes at least one lens separate from but aligned with the lens in the body of the mobile phone. The lens at the lens station is located between the camera lens of the mobile phone and the object to be photographed and the lens of the lens station is adapted to magnify the image of the object. The carrier member further includes a light source mounted thereto. The light source is adapted to illuminate at least a portion of the object to be photographed. The light source being mounted to the carrier member such that the light source is movable relative to the base and the phone cover, and the light source is separate from but operatively associated with the light in the body of the phone so that light from the light in the body of the phone is coupled to the light source on the carrier member and the light exits the light source and is projected toward the object to be photographed.

A vision correction device may include a sheet of transparent material including a converging lens. The converging lens may be configured such that, when the sheet of transparent material is disposed adjacent to a surface, the converging lens refracts light from an image on the surface with an optical power that shortens a viewer's nearpoint distance by an amount that is the same or greater than the reduction in nearpoint distance provided by a 1.0 diopter corrective eyeglasses lens when worn by the viewer.
