lines in a drawn state and is shown in broken lines in an undrawn state referring to fig2 5 the peep sight 10 construction will now be described in more detail the peep includes a body 12 having opposing surfaces u2014 a front surface 14 and a rear surface 16 because the front surface 14 is on the target side relative to the archer it is also referred to herein as a target surface because the rearward surface 16 is on the archer side it is referred to herein as the shooter surface these target and shooter surfaces 14 and 16 can be parallel to one another as desired as shown in fig3 5 the body 12 generally forms a circular disc however the body can take other geometric forms depending on the application the body 12 also defines a peep aperture 20 that passes completely through the body the peep aperture 20 can include a longitudinal axis 22 that is substantially orthogonal to the target surface 14 and or the shooter surface 16 the aperture 20 is bounded by a curvilinear bulge 24 this bulge 24 forms or at least contributes to an hourglass configuration of the aperture when a cross section of the body 12 fig5 is considered where.
