This is a 3D printed phoropter shield designed to fit onto the collar of the 25 mm forehead rest knob on the center of the phoropter. This phoropter shield was made at the request of optometrists and ophthalmologists that our group works with as the working distance of a phoropter places a practitioner very close to a patient's face. The goal here is to have a shield that will help protect both practitioner and patient while a refraction is being performed.

Our group has verified this design to fit onto Leica, Reichert, and Marco phoropters, though we believe that this should fit onto nearly any modern phoropter 25mm forehead rest knob collar (i.e. AO style phoropters). The design is press fit onto the collar which prevents flex in the shield compared to other designs which are loosely fit. It adequately provides coverage at all ranges of PD as tested by our ophthalmologists, and does not interfere with the cross cylinder accessory.

FFD print times (PLA) take approximately 50 minutes for one shield at 0.380 microns of resolution. To the best of our knowledge, this is the first 3D printed phoropter shield available. Because this is a 1 piece design, a 3D printer with a larger build volume (e.g. Lulzbot TAZ6, Prusa i3 mk3s, etc) is required.

No rafts or supports are needed.
