paper
overall: 240 mm x 177 mm

Technical Bulletin from a contact lens manufacturer. Portrait format, printed in blue on both sides of a single sheet of white paper. Describes a method of considering haptic lenses in four quadrants in order to overcome problems concerning nasal limbal touch, superior limbal touch and apical corneal touch associated with too large a bubble. The bulletin ends by suggesting that a small trial set of nine lenses is sufficient to prove the value of these new techniques.
