Glare Acuity Tester

Created by Dr. Brett Irvin at the Columbus VA in Ohio. One design fits over either a WA or Heine Transilluminator (must print appropriate tube gauge or use 7/32 drill bit to widen). Requires a little bit of hot glue to serve as a diffuser for the light at the base of the bowl. *Must use a small dab from a glue gun to create a diffuser effect at base of bowl into tube.*
-> Updated in 11/2020: we have attached the plug with a hinge so it doesn't fall/wander. A hot air gun or hair dryer can help with installation of the hinged plug.
