Vision monocular

A variety of disorders may lead to rapid, painless, monocular or binocular vision loss. This may include central retinal artery occlusion, acute narrow-angle glaucoma, trauma, or others. The differential diagnosis is complex and needs to be undertaken by an emergency department or ophthalmologist.9... 

But though we see with one eye the direction in which any object or point of an object is situated, w 6 do not see its position or the distance from the eye at which it is placed. In monocular vision we learn from experience to estimate all distances, but particularly great ones, by various tests, which are called the erfferta of dist ce, but it is only with both eyes that we can estimate with anythii like accuracy the distance of objects not far from us... 

Tlie most important advantage which we derive from the use of two eyes is to enable us to see distance, or a third dimension in space. Thai this vision is not the result of experience as monocular vision is, Is obvious from the fact that distance is seen a perfectly by children as by adults j and it has been proved by naturalists that animals newly-born appreciate distance with the greatest correctness. ... 

Monocular Vision.—Seeing with only one eye, When one eye is closed, as some do in taking sight with a gun, it Is a case oE monocular vision. 

INSTRUCTIONS When other than the Snellen chart Is used, give test results In Snellen-comparable values. In recording distance vision, use 20 feet as normal. Report visual acuity as a ratio with 20 as numerator and the smallest type read at 20 feet as denominator. If the applicant wears corrective lenses, these should be worn while visual acuity is being tested. If the driver habitually wears contact lenses, or intends to do so while driving, sufficient evidence of good tolerance and adaptation to their use must be obvious. Monocular drivers are not qualified.

Although monocular vision does not preclude driving in general, many countries restrict commercial driving to people with binocular vision (e.g., Australia, see Horton and Chakman, 2002 USA, see FMCSA, 2001). Critical reviews of research tiiat compared the crash rates of monocular drivers with that of binocular drivers have for the most part concluded that monocular drivers are no worse than binocular drivers (Bartow, 1982 North, 1985 Owsley and McGwin, 1999). In one study that was conducted on California heavy vehicle drivers, Rogers et aL (1987) did find that monocular drivers had more crashes than binocular drivers, but the latter tended to under-report their crashes. This anomaly was due to the fact that monocular California drivers did not drive outside of California, because they did not comply with the Federal vision requirement of binocular vision. The binocular drivers did drive outside of California, but their California license records did not include tiieir out-of-state crashes. 

The required fields of view for all Classes are defined using ambinocular vision, see Fig. 5. According to [1], ambinocular vision defines the total field of view obtained by the superimposition of the monocular fields of the right eye and the left eye. 

Thus, the generic computer vision tools of dense depth and optical flow reconstruction are replaced by an optimized method for highway traffic scene reconstruction A monocular rear-view vehicle mounted camera setup is utilized to estimate the road course, the vehicle distances, and their trajectories. This output data is post-processed in a perceptual motivated rendering stage to enrich the rear-view camera video stream with motion and distance cues. 

We conducted a prospective cohort study of 32 offspring of women who were exposed occupationally to organic solvents during pregnancy compared with 27 nonex-posed children. Monocular and binocular color vision and visual acuity were assessed using the Minimalist Test and the Cardiff Cards, respectively. Children with known hereditary color vision loss were excluded.
