This paper reviews the current visual acuity standards for UK drivers. These standards have changed in recent years such that car drivers (Group 1) now have two standards to meet: reading a number plate at 20m, and achieving an acuity of 6/12. In the light of these changes, research ...
visual acuityvisual field defectsWe evaluated the prognosis of visual fields, visual acuity, and fitness to drive and the phenomenon of statokinetic dissociation in patients with pituitary adenoma who undergo surgery. In patients with pituitary adenoma, visual requirements for on road driving performance...
Visual AcuityEyePurposeTo assess driving status, habitual visual acuity (VA) in the better-seeing eye, and self-reported driving difficulty among patients diagnosed with age-related macular degeneration (AMD). DesignCross-sectional cohort study of 553 AMD patients' habitual VA, self-reported driving...
High visual acuity is essential for many tasks, from recognizing distant friends to driving a car. While much is known about how the eye’s optics and anatomy contribute to spatial resolution, possible influences from eye movements are rarely considered. Yet humans incessantly move their eyes, and...
All the participants were required to have normal or corrected-to-normal vision. The participants were requested not to use digital devices or watch television (TV) 1 h before data collection to avoid visual discomfort and fatigue. 2.2. Apparatus Visual acuity was measured using an OPTEC 2000P ...
Visual acuity tests can also determine whether: An infant or child has propervisual development. A person has the required visual acuity to get adrivers license. A personqualifies for special servicesdue to decreased visual acuity. A disease has progressed and caused changes in vision. ...
For eyes with presenting visual acuity of 20/30 or worse, visual acuity was also measured aided by the automated refraction result (corrected visual acuity). Simple (character recognition) literacy was required for visual acuity testing. Visual acuity was not tested in participants who were too ...
When feedback is associated with changes in performance, it may increase the efficiency of learning, especially in difficult conditions, which has been shown, for example, in motion-direction discrimination31. Feedback may also promote visuomotor skill acquisition by driving learning in the motor ...
Abstract. Metamorphopsia is a common symptom in different macular disorders. Micropsia and macropsia are special types of metamorphopsia. Recent theories
and can be used to perform other visual examinations by the preparation of other stimulus films, such as glare recovery (using a strobe flash tube addition), motion perception thresholds, visual tracking ability (using an eye tracking monitor addition), visual acuity (using an appropriate stimulus...
