These Hand Held Maddox Rods are made of ABS plastic-the same tough material used to make football helmets. They will not break or shatter.

When the Maddox lens is mounted at 45 degrees it is very easy to switch from a horizontal line (generated by a penlight)  to a  vertical line from the patient's point of view. Simply maintain the same 45 degree angle of the handle and flip the Maddox handle. Patient's view of the line changes from horizontal to vertical.
