The structure of the eye contains several complex structures that make the eye like so of a camera. Without using complex equipment to view all parts of the eye or dissecting it, one can see three structures of the eye: the sclera, the iris, and the pupil. The white part of the eye is known as the sclera which is the outer most part, that helps the eye maintain its shape and protects the eye from injury. The black dot one can see in the middle of the iris is known as the pupil. The pupil is in…

Have you ever wondered why we see illusions in different ways or why we say a word instead of a color? The Stroop Effect shows that something is going on in our brain. But what does it tell us about our brain’s ability to process colors, words, and illusions? Is it something that happened during development or is there something that happens in our brain when we look at illusions? The Stroop Effect is named after John R. Stroop, who discovered this phenomenon in 1935. The Stroop Effect states…

Introduction Central retinal vein occlusion (CRVO) is a blockage in the main blood vessel that carries blood away from the retina (central retinal vein). The retina is the part of your eye that senses light and that sends signals to the brain that allow you to see. CRVO can cause you to have blurry vision. It can also make you lose some or all of your vision. The condition usually affects only one eye. What are the causes? This condition is usually caused by a blood clot that forms inside the…

The work of art I chose -- “Sphere Lutétia” is created by Jesús Rafael Soto. He was a Venezuelan op and kinetic artist who born in 1923 and passed away in 2005, at the age of 81. Most of his artworks have shown the connection to space. This particular artistic form developed by Soto is broadly known as the “Penetrable”. The “Sphere Lutétia” that created in 1996 is regarded as a representative one. It has been exhibited in "Les Champs de la sculpture” in Paris and Miami Art Basel in 1996. And it…

Light is what helps us see every day, and without it we know that it would be much harder to observe our surroundings. Light helps us see the detail in objects and the beauty in our environment. Thanks to a few functions of our eye we can gather that light to form an image on our retina. For many people, eye sight tends to get worse as they age and corrective lenses are needed. Contact lenses provide a comfortable way to allow someone to see things with a 20/20 vision. To understand how the…

This spring semester in my 1301 art class we attended the Martha Fenstermarker Memorial Art Gallery at Laredo Community College. I must say that my attention was captivated by the art that was being displayed though out the gallery. Although the paintings on the wall were smaller than expected, they each had amazing detail. “Beirut Sea and baby” by Lahib Jaddo is a stunning acrylic on panel art work that caught my eye and blocked out the rest of the exhibitions. This acrylic on panel piece…

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…

Colour Grading Assignment 1 First and foremost, Billy, Liz, and Jessica all agree that we will not use this footage for any purpose beyond this assignment. The scene from the show Annedroids provided to us includes four characters having a conversation outside, one of these characters being a CGI robot. The scene consists of seven different shots that vary in lighting and colour, posing a problem for the colourist who would need to adjust them for continuity. One of the noticeable challenges…

What are truffles? Truffles can be depicted as an edible gourmet mushroom that comes greatly prized and yet sought after by many food lovers. They can also be described as fungi that grow completely underground and have a symbiotic association with the roots of specific trees, mostly oaks. Truffles are known to have an overpowering, strong, earthy, delicate scent and provide an exceptional flavor and aroma to food. Though the truffle is mostly used in very small amounts, its flavor and aroma…

Assignment 228 . What is the refractive error? Normally, the rays of light entering the eye are brought to a precise focus on the retina, the light sensitive layer lining the back of the eye. When such a focus is not achieved, a refractive error results and vision is not clear. These defects in the focusing power of the eye are called refractive errors, most common symptoms of refractive error is blurry vision. Ophthalmologist can serve the patient by asking questions and obtain information,…
