Abstract
Cataract development is a very gradual process of normal aging but can occasionally occur rapidly. Many people are unaware that they have cataracts because the changes in their vision have been so gradual. Cataracts commonly affect both eyes, but it is not uncommon for cataracts in one eye to advance more rapidly. Cataracts are very common, Experts have estimated that visual disability associated with cataracts accounts for over 8 million physician office visits a year in the United States. This number will likely continue to increase as the proportion of people over the age of 60 rises (Paine David A., 2014). In this paper, I will explain the symptoms, causes, treatments and …show more content…

Specific proteins within the lens are responsible for maintaining its clarity. Over many years, the structures of these lens proteins are altered, ultimately leading to a gradual clouding of the lens. A cataract scatters the light as it passes through the lens, preventing a sharply defined image from reaching your retina. As a result, your vision becomes blurred. As you age, the lenses in your eyes become less flexible, less transparent and thicker. Age-related changes can cause tissues within the lens to break down and clump together, clouding small areas within the lens. As the cataract continues to develop, the clouding becomes denser and involves a greater part of the lens (Mayo Clinic Staff, 2013). Rarely, cataracts can present at birth or early childhood as a result of hereditary enzyme defects, and severe trauma to the eye, eye surgery, or intraocular inflammation can also cause cataracts to occur earlier in life. Other factors that may lead to development of cataracts at an earlier age include excessive ultraviolet-light exposure, diabetes, smoking, or the use of certain medications, such as oral, topical, or inhaled steroids (Paine David A., …show more content…

These symptoms also can be a sign of other eye problems. If you have any of these symptoms, check with your eye care professional (National Eye Institute Authors, 2009). Having cataracts is often compared to looking through a foggy windshield of a car or through the dirty lens of a camera. Cataracts may cause a variety of complaints and visual changes, including blurred vision, difficulty with glare (often with bright sun or automobile headlights while driving at night), dulled color vision, increased nearsightedness accompanied by frequent changes in eyeglass prescription, and occasionally double vision in one eye (Paine David A.,

Summary Of A Cure In Sight By David Dobbs

In order to reverse or prevent some types of eye damage, variations of gene-replacement, or the identifying a mutation that cripples retinas and fixing the problem by slipping a good copy of genes into the eye, could find, or even fix similar genetic defects early on. In addition to gene-replacement, stem cells, or cells in early stage of development, replace or reduce the failing retinal cells that cause blindness. Dobbs also talks about bionic retinas, or microchips that replace failed retinal cells by collecting or amplifying light. They bring a low-resolution version of sight to people with histories of blindness.

The Stroop Effect On The Brain

756 Words | 4 Pages

In the eye, the cornea is entry point for light. In simple terms, the cornea is the transparent tissue at the front of the eye that functions as the window through which all light has to pass through on its way to forming visual perception. The reception of a clear image is dependent on the integrity of the corneal surface. However, with age, the lens is subject to cataracts and presbyopia in addition to other damage. This damage to the surface of the eye effects how people see and could potentially slow their reaction time to what they are seeing.

This was surprising because I didn 't think that proteins would come from our eyeballs. Turns out that the retina in our eyes which is just a layer of cells that are photosensitive (they respond to light), the photoreceptor cells contain photopigments (light-sensitive molecules), these molecules are made up of the protein opsin. This is just one way that proteins get onto our contact lenses. THe proteins that come from the eye and create build up on our contact lenses have to be broken down or it can lead to other issues like a protein buildup in on the
