A Description Of The Symptoms Of Cataract
Total Articles: 1
Cataract is a cloudy area on the lens of the eye. The problem can appear in a only one eye or both. One eye is typically further affected than the other if cataract appears in the two of them. So that the patient can observe well-defined imagery, a translucent lens permits light to pass through to the back of the eye. Light can not pass through easily if a part of the lens becomes opaque, so the patient's sight becomes hazy like seeing through a fogged-up glass. When the lens becomes more cloudy, the person's eyesight will become worse.
The globe's leading cause of blindness is cataract, with 18 million persons blind as a consequence. Nowadays, it has become a regular eyesight issue related to getting old. About 22 million Us citizens age 40 and older have cataract, and the older someone gets the greater the risk of getting it. African Americans as well as Hispanic Americans are at particular high risk of getting cataract, and it is more likely to occur in females than men.
There are other factors besides age that may increase the probability of cataract development. These are:
-Drugs such as steroids
At the beginning, cataract may have a minor impact on your sight because the lens is not very affected. Thus, you may not discern any loss of eyesight. As the cataract progresses, it distorts the light passing through the lens. Symptoms and signs are more noticeable once this happens. Symptoms of cataract are relative to its position in the eye (cortical, nuclear or posterior sub capsular). The next symptoms may be noticed by patients who suffer from cataract.
These form of cataract commonly occurs in old persons.
-Opaque, foggy or blurry sight
-Seeing through frosted glass can be compared to it
-Little dots or spots interfering with vision
-Parts of the vision field are blurred since the patient sees little patches
-Vision worsens with dim light
-There is glare from very intense light
-Several individuals who suffer from cataract mention that colors are less vibrant
-Initially, reading is hard and subsequently impossible
-Frequently, glasses are required to be changed
-Soon or late using glasses becomes less effective
-Street lights and car headlights provoke a halo around them for some persons
-Double eyesight in one eye (unusual)
-Hazy distance eyesight and glare increases
Regularly, the outer area of the lens is where this type of cataract begins.
-At first, cortical cataract has a minor impact on vision
-As this cataract increases and gets to the middle of the lens, glare can happen
-There may be issues with contrast sensitivity, clarity and distance vision
Posterior Sub capsular Cataracts
The occurrence of this sort of cataract begins near the center of the back area of the capsule surrounding the lens. Typically, this cataract promptly advances. Major impairment of eyesight, including near-vision troubles and glare, occur to many patients.
