His work has led to the development of a unique apparatus designed to assess dark adaptation, which is crucial for understanding visual performance in low-light conditions.
Latest Patents
David M O'Brien holds a patent for an "Apparatus for testing dark adaptation." This apparatus comprises a test panel featuring four test stimuli, which are arrays of light-emitting diodes arranged around a fixation light-emitting diode. Translucent covers are mounted over the arrays, and four switches allow a subject to input the identity of a visible test stimulus. The apparatus randomly selects a test stimulus and switches it on at a predetermined level of luminance. Upon correct identification, another stimulus is selected and switched on at a reduced luminance level. The times from the commencement of the test until various correct identifications are recorded, along with the corresponding luminance levels of the test stimuli. This innovative design enhances the accuracy and efficiency of dark adaptation testing.
