FIG1 is a bottom perspective view of an illustration of modular spectacles 100 in an assembled state, according to an example embodiment. The modular spectacles 100 may be assembled and disassembled without the use of tools. The modular spectacles 100 comprise a frame assembly 105 that holds a pair of lenses 110, 112 (a left lens 110 and right lens 112) and a pair of temples 115, 117 (left temple 115, right temple 117). The proximal tip 125 of left temple 115 is seen extending through the frame assembly 105. The proximal tip 127 of right temple 117 is also seen extending through the frame assembly 105. The temples 115, 117 comprise extended arms located on the sides of the frame assembly 105 that extend from the frame assembly 105 and over the ears to keep the spectacles on the wearer's face.
