Bimocular Vision is a coordinated use of two eyes and brain, in order to produce a single unified image in space with three dimensions.
Perfect binocular vision requires three faultless mechanisms:
1. Sensory mechanism:
2. Motor mechanism:
3. Mental mechanism or mental process:
Advantages of Binocular Vision:
1. Stereopsis -- Ability to perceive depth is the greatest advantage of Binocular Vision.
2. Higher visual acuity.
A combined visual acuity is better than a single eye visual acuity.
3. Enlarged field of vision.
More area of seeing with overlapping.
Then, Grades of Binocular Single Vision:
Binocular vision has three grades:
GRADE I : Simultaneous macular perception (SMP) GRADE II : Fusion
GRADE III : Stereopsis -
All these grades can be tested easily on a machine called Synoptophore.
Please watch the video in full to get a comprehensive knowledge of Binocular vision.
