Optometry plays an important role in both diagnosing and managing binocular vision disorders. Binocular vision disorders have been associated with increased near-work symptoms1 and reduced academic achievement,2 while successful treatment of a binocular vision disorder has been associated with reduced adverse academic behaviours and reduced parental concern regarding academic achievement.3 A binocular vision assessment is…

This essay will explore the development of visual acuity and depth perception within the first year of an infants life. It explains the reason for the fast development of visual acuity within the first 6 months and the development of visual acuity based on how cone photoreceptors and the fovea mature to provide good resolution.…

Over the first year of life, many developments in the body occur including speech advancements, fine and gross motor movements, facial expressions and the fusion of bones. One of these advancements includes the progression of our eyesight- vision is a powerful sight that allows us to protect ourselves from the environment by reacting to stimuli;…

What is it? Color vision deficiency, also known as color blindness, is a condition that affects an individuals ability to differentiate between colors, specifically those of similar hues. The inability to distinguish between colors results from either a partial or total loss of color vision, depending on the type of color blindness present (National Institutes…

Introduction In this modern era, everyone has certain deficiencies in their body. These deficiencies will lead to many serious complications. These complications may be of bones, joints and of many other body parts. As you all know, eye is the most sensitive part of our body and it works excellently. You can easily differentiate different…

There are several aspects of the optical system which contribute to normal visual development in infants, and retinal development is essential for this. Retinal factors take 4+ years to reach full adult maturity. Receptors are found in the fovea and peripheral parts of the retina. Vision rapidly improves after birth due to changes in the…

To most people, they may seem like normal activities catching a sunset, seeing the beautiful waves of a beach, or watching an artistic performance. Yet, for the 285 million human beings around the world who are blind or visually impaired, the full splendor of those moments can only be imagined or described. For those individuals,…

Introduction – Vision is maybe the key of our means. Certainly, all sections of the eye are critical for viewing a conventional picture, the most fundamental layer for illusion is the retina. The retina is a bit of neural tissue that lines within the eyeball. The vivid intensity that drops on the neural cells of…

In this essay, I have chosen to review the article The dimensionality of color vision in carriers of anomalous trichromacy (Jordan et.al, 2010). The purpose of this essay is to show the differences and similarities between primary and secondary articles as well as how secondary articles are gathered and findings taken from primary articles. This…

Phenomenal vision is the sight of colors, brightness, depth, shades, and motion, generated by light distributed on the retina (Stoerig, 2001). Undeniably, there are phenomenally unconscious visual mechanisms occurring within an individual’s retinal processes and occipital lobe activity does not correlate with visual awareness. Research into the study of vision and whether the phenomenal vision…
