is placed between an observers eye line of sight indicated by the arrow and a reticule of sight 10 though by suitably arranging the optics of the sight any arrangement is possible for example placing the weapon aiming device over a second end 20 of sight 10 the weapon aiming device may include a circular tinted disk 14 with a hole at its center placed at one of a flexible sleeve 12 sleeve 12 enables easy attachment to an optical or similar functioning sight 10 the tint may be of any color however it has to be of sufficient intensity and contrast to the coloring of the attached sight system e g sight 10 to enable the hole at its center to be visible and superimposed on the reticule of sight 10 diameter of hole 18 at the disk center should be optimized for the geometric shape of the symbol of the reticule e g cross hairs alternatively hole 18 could simply be an area of contact with the remaining area of disk 14 as long as there are sufficient conditions and difference in color between disk 14 and lenses incorporated within sight 10 in one exemplary embodiment a diameter of approximately 1 mm is an expected order of magnitude for this hole or contrasting area the aiming device may include multiple disks 14 mounted in sleeve 12 one behind the other each one being easily removable such that the overall transparency may be altered to better suit ambient light conditions the multiple disks may incorporate different hole sizes such that removal of one or more may alter a size of the hole presented to a user of the aiming device the aiming device may also include a number of optically.
