The Importance Of Glaucoma Awareness Month It is estimated that there are 60 million people worldwide living with glaucoma. Three million of those people live in the United States. January is National Glaucoma Awareness Month. The purpose of Glaucoma Awareness Month is to raise awareness about this condition and to encourage people to get screened. What Happens If Glaucoma Is Not Treated? If glaucoma is not treated, then vision loss will occur. During the first stage of vision loss, people will start to see blind spots in their peripheral vision. This can make activities like driving very dangerous. During the second stage of vision loss, people will begin to experience tunnel vision. This is known as the total loss of peripheral vision.
Glaucoma is a disease of the eye and it is fluid pressure within the eye rises and if the eye is left untreated the patient might lose vision or maybe even blind. But this disease is generally affects both eyes but although one of their eyes may have more severe signs or symptoms then the other eye. When you have glaucoma there are small spaces in the front of the eye and they are called anterior chamber. There is clear liquid that flows in and out of the anterior chamber and the fluid nourishes and bathes nearby the tissues. And if the patient has glaucoma the fluid dose not drain like it should drain but the fluid drains out of the eye. And this may lead to fluid build up and pressure inside the rises of the eye. Unless the pressure is brought down and controlled and the optic nerves and some of the other parts of the eye might become damaged leading to ...

Eyes are the ‘organ of sight or vision; the visual sense; the sense of seeing’ (Biology-Online). The eye is an organ that detects light and sends signals along the optic nerve to the brain. The eye allows for light recognition and the ability to differentiate between colors, and light and dark. The eye is approximately 2.54 cm wide, 2.54 cm deep and 2.2 cm tall. The human eye has around 200-degree viewing angle and can see and detect more than 10 million colors and shades. This essay is going to look at ways of seeing. The possible problems with eyesight, and eyes of various kinds. It is one of the most rare problems today that is affecting people, all over the world. Around the world an estimate of 4 in 10 people have perfect vision/sight (BBC). The population of the world right now
The human eye’s ability to view focused images of both nearby and distant objects is dependent upon its capacity to accommodate. When you want to look at something nearby, the lens in your eye assumes a large curvature, resulting in a shorter focal length. Conversely, your lens becomes flatter in shape and takes on a longer focal length when you want to look at a distant object. Accommodation is key in allowing your eyes to use its muscles to change focal lengths in order to see objects at a variety of distances. When you lose the ability to accommodate, the lenses in your eyes become locked to focus on either near or far away objects. In the case of nearsighted individuals, light entering the eye can only focus on objects nearby. As a result, distant objects appear blurry because light is focused in front of the retina, or the light-sensitive tissue layer at the back of the eye, instead of directly on it.
A person can be blurry and feel loss of vision for a couple hours after consuming alcohol, but that certainly has a negative impact while driving. First of all, it is illegal to drive while one is still under the influence anywhere in the United States. Alcohol may not only give a person short term blurriness, but also a possibility of losing vision completely. Alcohol slows down the speed of communication between the brain and the body. Once communication is slow between the body and the brain, eyes will not be able to communicate as effectively like they used to when the person was normal, which makes one have poor vision. A person who is driving while he is still drunk may not be able to focus on driving. For example, if a person is under the influence of alcohol he/she will have a hard time keeping a car on the lane and possibly end up colliding if he/she is over
Blind-sight is when the patient is legally blind but can perform tasks of everyday life as if they were able to see perfectly. (not able to see but are able to perform tasks as if they are able to see, zombie?)
There are three different types of glaucoma, the most common glaucoma is the open angle, or chronic glaucoma. The open drainage angle of the eye can become blocked leading to an increase of eye pressure. The optic nerve damage and vision loss occurs slowly and painlessly making this disease the worse to handle because the person has no idea they have open angle glaucoma until the optic nerve is to badly damage for any treatment. The second type of glaucoma is the angle closed, which happens when drainage angle of the eye becomes narrow and completely blocked. When the eye suddenly becomes blocked completely, the pressure builds up known as acute angle-closure. When drainage angle of eye becomes completely blocked and pressure eleva...
Black history did not always have the pleasure of having a month dedicated to it; it used to be restricted to a single week, called “Negro Week,” to coincide with the birthdays of Abraham Lincoln and Frederick Douglass (Adetoro). African historian and journalist, Carter G. Woodson, began this week in 1926, in an attempt to inform others of the accomplishments as well as the devastations African Americans had experienced (Bambrick). Woodson’s timing was crucial; he initiated this week in a time where blacks and whites were separate and seen as indifferent. It was not until 1976 that President Ford graciously expanded it to a month (PBS). Black History Month is a time for celebration and remembrance -- or so America tells us. Black History Month
When most people think of blind people, they tend to picture a person with dark sunglasses, a seeing eye dog, and a walking stick. These are stereotypes and obviously do not remain true in the case of all blind people. In Raymond Carver’s short story “Cathedral," the main character is jealous and judgmental of his wife’s friend who happens to be a blind man. It is the combination of these attitudes that leads to his own unique “blindness." It is through this initial blindness, that the character gains his greatest vision.

This is a very rare complication wherein you may have loss of vision due to surgical complications.
Definitely, if you develop a sudden change in your vision, sometimes double vision or blurred vision (Mayoclinic.org 2013). There are different locations of cataracts therefore they have names based on their location. According to “Cataracts” Linton 2012, a central cataract is located in the center of the lens (nuclear cataract) and in this case the patients may still be able to use their peripheral vision just as they always have, they just tend to start to lose vision directly in the center of their eye. The second type of cataract, according to “Cataracts: Linton 2012 is the peripheral cataract (cortical cataract) where an individual can see straight ahead but cannot see out of either of their peripheries. There are cataracts that affect the back of the lens (posterior subcapsular cataract) in which the cloudy spot on the lens forms directly over the small area where the path of light shines on the retina. This type of cataract interferes with reading vision, distracts us and hurts our eyes when we are in bright sun light, and happens to case the “halos” that some people say they are seeing (Mayoclinic.org 2013; “Cataracts” Linton
Corneal- it’s like seeing two rather than one. ( focuses on 2 in the retina rather than 1)
The images formed on the two retinas are so unlike that they cannot be blended in the brain. Thus, a double image is perceived. The condition is known as diplopia, or double vision. Prismatic lenses are prescribed to correct this defect.Imperfections in the cones of the retina, resulting from heredity or disease, cause defective color vision. This is known as color blindness, or Daltonism. In total color blindness, everything appears in shades of gray.
