Abstract
An optical occluder adapted for use with monocular optical instruments having a variety of shapes and sizes, for blocking the vision the user's eye that is not looking through the instrument. The occluder includes a central retainer body to which are attached both a generally planar eye shield and a elastic cord of adjustable length. The cord can be selectively wrapped around an optical's instrument's eyepiece, to hold the occluder in a stable position relative to it, and the eye shield can be selectively positioned both radially and circumferentially relative to the central retainer, to suit the user's particular eye spacing and comfort.
