The Response of the Flicker Fusion Threshold
Flicker fusion threshold (F.F.T.) means the frequency with which successive flashes of light must occur to just appear to the eye free from flicker. A simple portable machine is described which will deliver flashes of light at any required interval. Patients with hypertension or anemia have a lower than normal F.F.T.; furthermore, administration of nitroglycerin, 0.4 mg. sublingually, or papave...
متن کاملCritical flicker fusion test of potential vision.
PURPOSE To continue developing a potential vision test based on the critical flicker fusion (CFF) phenomenon by using a brighter stimulus and optimizing its size. SETTING Flinders Eye Centre, Flinders Medical Centre, Flinders University, Bedford Park, South Australia, Australia. METHODS In a prospective nonrandomized study, 225 participants were assigned to 1 of 4 groups: normal, media opac...
متن کاملThe effect of hypoxia on the critical flicker fusion threshold in pilots.
OBJECTIVES Human reactions to environmental changes have been the subject of numerous investigations related to pathophysiology, aviation psychology, aviation, and sports. The present study aimed at evaluating the perception of light stimulus via the Critical Flicker Fusion threshold (CFF) measurements among aviation pilots. MATERIALS AND METHODS The study was carried out under hypoxic condit...

15 صفحه اولTwo Visual Training Paradigms Associated with Enhanced Critical Flicker Fusion Threshold
Critical flicker fusion thresholds (CFFTs) describe when quick amplitude modulations of a light source become undetectable as the frequency of the modulation increases and are thought to underlie a number of visual processing skills, including reading. Here, we compare the impact of two vision-training approaches, one involving contrast sensitivity training and the other directional dot-motion ...
