Visual perception

Design an experiment to test the following two questions: 1) Do infants detect the difference between 2 visual patterns by 2 months of age? 2) Is the ability to detect the difference between 2 visual patterns innate? Answer the following: a) For the first question, the participants will all be infants that are 2 months of age, give or take a few days. For the second question, the participants will be infants that are 1.5 months of age, give or take a few days. This age is around the time…

Our eyes work like a camera. Just like a camera lens focuses our cornea focuses light on the membrane called the retina. The cornea is transparent. It's found in the front of the eye and it helps focus light. Behind the pupil is a colorless, see threw structure called the crystalline lens. A clear fluid called the aqueous humor fills between the cornea and iris. The cornea focuses most of the light and then it goes through the lens. Behind the cornea is a colored, ring shaped membrane called…

How Does Ocular Dominance Affect the Way We See Things? Eyes are what allow our brains to process information, whether it’s to see color or to give the ability to read. They are organs that even allow us to evaluate our health, and can be used to express emotion. Everyone has them and each one is different, but they share a common purpose, and it’s important to know how they work. Light passes through the cornea of the eye, which has the job of protecting the eye and refracting the light so…

Color Visual & Invisible Uniform 1. The color visual system is a major component of a human because it helps us interpret between the color, depth, size, and shape of an object. In asking to create a synthetic or artificial color visual system you would first need to create an eyeball that could mend its size to the person’s eye socket. Thus theoretically making an artificial retina in the process of making the eyeball. This would have to take the creation of artificial photoreceptors as well…

in optometry. As I have stated in several posts over the term, optometry (like dentistry or even public health) is a vastly underrated field of medicine. And with my long-term dream of getting into pediatric optometry and working with children with visual impairments, I saw an opportunity to bring the eyes and community health assessment into one project. Largely due to more accessible data sources and information, I found this project was achievable with minimal difficulty compared to the prior…

The article “Dismembered human feet keep washing up on beaches in western Canada” started off with a video clip. In the video, a woman was stated her concern on the statement that was made about the foot that had washed ashore, the statement of “there is nothing to see here”. Continuing the conversation, the men stated that this foot was the 14th foot that had been washed ashore around the beach of the Salish Sea in the last century; and one of the only connections between all 14 of the foots is…

Monali Joshi, Group 8. Human Visual System Eyes are the entry purposes of the light that conveys the visual data about the onlooker's surroundings into the human visual system. The approaching light is consumed by the photoreceptors in the retina and changed over to electrochemical signs, and these signs are transferred to the resulting systems of the visual pipeline. The photoreceptor cells change over light into electrochemical signals, and are separated into two sorts, rods and cones, named…

As I take you through the path of light I will be explaining what each structure is responsible for and how it handles light. As I get to the path light takes as it enters our eyes I will point out four mechanisms that have to function in order for us to see. Each of our eyeballs have six muscles that attach them to our skull. Four of these muscles pull straight and are called rectus muscles. Two of these muscles pull on an angle and are called oblique muscles. The first mechanism is the…

For a person that has never lived with a physical challenge such as being blind, deaf, or wheelchair bound it is very eye opening experience to the struggles that many have to deal with on a daily basis. I chose to try and function without sight for four hours to see if I could manage. I have worked in the past with those that have been blind for many years and I must say they were very self sufficient with one gentleman even walking several blocks to work each day unassisted. What I found when…

medical history relevant for abdominal migraines and a 9 millimeter in diameter complex pineal cystic gland, incidentally found at age 5 and being followed by Neurosurgery with no interval changes over the past year. On initial exam his best-corrected visual acuity (BCVa) was 20/30 in both eyes (OU) with no afferent pupillary defect. Color vision, stereopsis, motility and ocular balance…
