Abstract: An handheld illuminating device with orb-shaped lens for enhancing forward and lateral visibility including a flashlight having at least one light source that emits light rays through an orb-shaped lens. The orb-shaped lens is semi-spherical and adapted to disperse the light rays through a substantially 270° arc of uniform light for illuminating more than one area around the user, diffusing the light rays to soften the illumination from the light source, and eliminates shadows that are inherent in flat or curvilinear lenses. A reflector reflects light rays from the light source to the orb-shaped lens. A power supply powers the light source. A switch regulates power and intensity of the light source. A transparent cover protects the orb-shaped lens from physical damage.
