Advantages Of Binocular Vision

Title: Introduction to Binocular Vision
Introduction:
Binocular vision usually has a large area of binocular overlap and is used to code depth. In addition to its role in depth perception, binocular vision provides some other advantages. Performance on basic visual tasks such as detection, resolution, and discrimination is slightly better with both eyes open. Many complex visual tasks, such as reading, detecting camouflaged objects, and eye-hand coordination are also performed more effectively with two eyes than with one, even when the visual display contains no depth.
Objective:
To determine whether binocular vision has better advantages over monocular vision
Materials:
TNO/Titmus fly test, object (books), Snellen chart, occluder, and two

Both individuals was then able to have a perception of a single clear image and was able to perceive depth. The nervous system uses the binocular disparity between the two images to allow the perception of a three-dimensional world, in which the approximate distance of the object can be determined. If the disparity is too great, the nervous system is unable to fuse disparate binocular images. When an individual’s binocular visual field is not in alignment, the nervous system is not able to fuse disparate images and steadily adapts by ignoring the image formed from the deviant eye.

When tested monocularly, the patient had difficulties to complete the task

i. Why binocular vision is better than monovision?
Binocular vision provides a wider visual field. The visual acuity is slightly greater in binocular vision than the visual acuity of one eye. Optical defects present in one eye are made less evident by the normal image of the opposite, involving the use of the blind spot of each eye, and stereoscopic vision and depth perception occur accurately with binocular vision. ii. How would you educate your patient on the importance of treating symptomatic binocular anomalies?
It is imperative to educate patients through counselling or through raising awareness via campaigns. Communicating with the patients about treating their binocular anomalies should be done to improve their visual acuity as well as their visual performance.

Conclusion
There are many advantages of binocular vision when compared to monocular vision. The visual acuity, visual field and eye-hand coordination is better during binocular vision. Perception of depth is enabled during binocular
