OBJECTIVE To establish normative relations between measures of visual function and cardiovascular variables that are important for age-related disease, including various forms of glaucoma. METHODS Foveal flicker sensitivities, resting blood pressures and heart rates, and intraocular pressures were measured in 18 individuals aged 40 to 68 years. All subjects had 20/20 or better visual acuity i...

The assessment of flicker fusion frequency (FFF), the stimulus frequency at which a flickering light stimulus can no longer be resolved and appears continuous, and critical flicker fusion frequency (CFF; the highest frequency at any light intensity that an observer can resolve flicker) are useful methods for comparing temporal resolution capabilities between animals. Behavioural experiments hav...

A low cost flicker-free field-sequential stereoscopic display has been developed. The system uses commercially available television products developed for the removal of flicker problems associated with the world interlaced television standards. These products reduce overall circuit complexity and implementation costs.
