A "low vision rifle scope" refers to a rifle scope specifically designed for individuals with impaired vision. Traditionally featuring large objective lenses to gather more light, high-contrast reticles for easier target acquisition, and adjustable diopters to compensate for varying eye power; essentially prioritizing clear visibility over high magnification.
Today's technology from companies like Digital FOV add an LCD targeting screen for easy visibility so there is no longer the requirement to focus down a scope tube or for a low vision person to try and line up iron sights.
Digital Crosshairs adaptive rifle scope technology enables a shooter to attach a removable HD camera to the eye piece of their rifle scope which displays the scope's field of view on a targeting display that is much easyier for prople with limited vision to target with.
