With the impending solar eclipse set to darken the skies briefly on Monday afternoon, physicians across the country are preparing to treat cases of optical damage caused by glaring at the “dark” sun. Unfortunately, many people believe that because the sun is blocked, it blocks the harmful ultraviolet rays from reaching one’s eyes, but that is not the case. Assistant professor in the University of Alabama at Birmingham, Tamara S. Oechslin, explains “it is never safe to stare directly into the sun, and that includes during the eclipse” (Janarthanan). But, these eclipses have been occurring for thousands of years. In fact, the ancient Chinese believed that solar eclipses were dragons devouring the sun (NASA). Obviously, the general population has come to a much stronger understanding of what a solar eclipse entails, but they do not necessarily follow guidance related to viewing the eclipse. In 1999, a solar eclipse occurred and “several thousand people rang helplines or attended special eclipse clinics” (Dobson). However, “the number of cases of solar retinopathy than was widely feared” (Dobson). Solar retinopathy is the damage caused by someone looking at the sun with improper or no eye protection. The retina, the home of light-sensing cells, is then damaged by the harmful rays of the sun. Treatment to try and heal the effects of solar retinopathy has proven ineffective (Dobson). Eyes are similar to the brain in terms of traumatic injury. Once a vital organ has been harmed, it
Sun Gazing is the practice of staring at the Sun for nourishment or as a spiritual practice. It is a Native American tradition, but has also appeared in many cultures, dating back as far as the ancient Egyptians, the ancient Yogis, and even the early Aztecs, Incas, and possibly the Mayans. It is believed to be a method of healing, curing physical and mental illnesses. Sun Gazing gurus have even claimed that it can lead to supernatural powers and immortality, and people who Sun Gaze long enough can become inedian, which means that they will no longer need to eat food to survive. Research has found that when direct sunlight hits the eyes, it moves through the retinal hypothalamic tract and continues into the brain, stimulating the Pineal

This paper talks about the solar flares and how they go on to cause global warming. Global warming has been an ongoing phenomenon and there are many reasons it has occurred. Apart from the green house effect, global warming could have been due to the solar flares that have occurred. Different researches and theories regarding this matter are discussed in the paper.
My inspiration for wanting to become an optometrist was jump-started by my aunt Rosemary. My aunt suffers from dry macular degeneration, and she first started losing her eyesight when I was about five years old. I have always been close to her, and I have seen her vision deteriorate. Today she can see peripherally. I have watched as she lost her driving privileges and was forced into an early retirement. I always viewed my aunt's condition without an appreciation of how lucky I truly was to have normal vision. However, In the summer of 2002 I visited an optometrist for the first time. Since that first visit to the optometrist 13 years ago, my eyesight has drastically deteriorated. I currently have a correction factor of -7.25 in my right eye, and a correction factor of -8.0 in my left eye. My vision has stabilized, but my high correction power, coupled with observing my aunt's macular degeneration, allowed me to understand that the gift of vision may not be an everlasting gift. I want to do my best to help people make the best of what may not be an enduring attribute of their lives.

“Eyes are like a telescope; you can see images that you could never imagine with the power of eyesight all you’ll be able to see is darkness.” This is why you should become an optometrist assistant so no one would ever see the darkness. You can help others with their problem of not being able to see clearly. Optometrist assistants are given the opportunity to help people see unbelievable images. They are under the supervision of an optometrist, along with some guidance.
For the health condition description of age-related macular degeneration I will discuss the etiology, onset, prevalence rate, body systems, body structures, and associated deficits that come and are associated with this disease. “AMD is the degradation of the cells at the center of the retina which is the layer of tissue at the back of the eye that registers light. The macula is responsible for ventral vision, which enables us to read, drive, participate in sports, and do anything else that requires focusing directly ahead. Macular degeneration distorts the heart of the vision field” (Macular degeneration, 1998). Sunlight and smoking are both influences of the onset of AMD (Age-related Macular Degeneration (AMD), 2014). It is suggested to avoid intense bright sunlight which may help reduce the retinal degeneration. Hats, sunglasses and any other accessories that can help protect the eyes from the sun are suggested. Cigarette smoking has also been linked to increasing the risk of developing AMD and it is recommended that persons should stop smoking to decrease their chance of developing AMD (Age-related Macular Degeneration (AMD), 2014). AMD does not develop until the sixth or seventh decade of life, although early
Glaucoma is a common and important health problem. It is one of the leading causes of blindness in Western Society (Hoskins & Kass, 1989). It is responsible for ten percent of all blindness in the United States and continues to be the second or third most common cause of blindness in the world (Bunce, Fraser, & Wormald, 1999). It is estimated that two million people in the United States have been diagnosed as having glaucoma. Glaucoma is known to affect about two percent of Caucasians beginning at the age of 40 with an increasing risk for those over the age of 60. This risk is especially high if a member of the family has glaucoma or diabetes. Further, there is a higher risk of a glaucoma diagnosis for African Americans
As humans, we don't always see with our eyes, but often with our imagination (Grunwald, 2016). Often times as people we never realize how useful our vision really is to us. You really don't think about something like that until it would actual happen to you. Throughout this essay, you will learn how the body is affected by Macular Degeneration (MD). Different signs and symptoms, as well as the etiology of MD, will be discussed. In the following, diagnosis tests and treatments may also be listed in order to help others who would like to know more about MD. Not to mention, you will learn the incidence and progression of MD. Furthermore, information though agencies and associations, as well as new research about MD will be given.
My motivation to learn more about the eye and its processes, as well as neuroscience and optical diseases are just two of the subjects I look forward to learning more about from the optometry program. Learning more about the body and its processes has been the most interesting subject for me. Ever since my parents began developing illnesses, such as diabetes, I have been determined to better understand the body’s
Nurses are placed in a position to make difficult decisions during the night shift when there are not enough staff members to handle patients that suffer from sundowners due to acuity differences from day shift to night shift. Many sundowner patients become agitated and even aggressive during the night shift, which day shift nurses do not experience when they assign patient acuity (Cipriani et al., 2015). During the night shift, nurses are given fewer, if any, certified nursing assistant (CNA) to assist in the workload of staffing. This limitation places nurses in the position of decreasing quality nursing care in patient safety.
In 2006 a young and slightly theatrical Julianna Klimeck was begrudgingly brought to the hospital after two days of incessantly bellyaching that her right eye was bothering her. Soon after, her parents, who had originally only made the trip in a desperate attempt to silence their often-overdramatic little girl’s conniption, were horrified to find out that their 8 year old had sliced her cornea. If they had thought their daughter’s “tantrum” before was unbearable, nothing could prepare them for the hysterics she would burst into when the ophthalmologist walked into the emergency room and announced that there was a fair chance that she could go blind in her right eye permanently.
As previously stated in the results section of this report, if there is a breakdown of the blood-ocular barrier, the amount of proteins present within the aqueous humour will tend to increase. When viewing the anterior chamber with a slit lamp, this increase in protein content will result in light being scattered. Flare is the term given to the presence of this scattered light. Flare is a common symptom seen in acute iritis and therefore would likely be seen in this patient with the use of a slit lamp.
If you spend lots of time outdoors, your eyes should be protected from ultraviolet. Avoiding UV associated eye problems require consistent use of glasses or sunglasses that block the sun's UV radiation. Lenses that block UV are less effective if they don't completely cover the eyes. UV light can enter the eyes by going around the lenses. In other words, the smaller the lens, the bigger the gap through which UV reaches the eyes. That's why sun glasses tend to be either large or tend to wrap around the
