Cataract symptoms

Many people know the term cataract but they don’t actually know what it is until they or someone that they love are diagnosed with cataracts in one or both eyes. A cataract is actually a clouding of the usually transparent lens of the eye. Despite popular believe, cataracts are not tumors growing on the eye or even the growth of skin over the lens of the eye; instead it is a fog that affects the lens itself.

There are a lot of untrue beliefs about cataracts out there. Many people believe that the condition is caused by an overuse of the eyes and that using the eyes will make the condition work, which is simply not true. In addition, there is a belief that the cataracts will spread from one eye to another, but this is also not true. Still others believe that a cataract is a form of cancer or is indicative of cancer, but this is simply not the case.

In a normal eye the lens is transparent or clear and one doesn’t usually take notice until it is no longer clear. When a cataract has formed, the lens will be quite cloudy and will look like a foggy window or even a frosted window. This is significant because the lens is located at the front of the eye and is responsible for focusing light on the back of the eye. When the light is able to pass through a clear lens it will pass through to provide the retina, or back of the eye, with a clear image of what is being seen. When the cataract forms on the eye, the lens is unable to produce that clear and concise light that will provide a sharp image to the retina.

Of course, there are some instances where the cataract is quite small or only covers a portion of the eye. In these cases the changes to the vision may be minimal. In these cases no treatment may be necessary, but if the cataract takes up a large portion of the lens sight will become impacts and may be lost fully if the cataract is not removed.

Unfortunately, cataracts form quite slowly, over months or even years. The result is that the changes to the vision are usually not noticeable until the cataract is quite large. In fact, if the cataract develops on the edge of the lens, there may be no changes in vision. It is often not until the cataract is quite large and fully developed that the person will begin to notice the symptoms. After diagnosis, the patient is often able to look back at the previous months and years and realize that there were some slow changes, but they were so slow that they didn’t notice them or pay all that much attention at the time.

Cataract symptoms vary from individual to individual but they usually start with hazy, fuzzy, or blurred vision. A lot of people also develop dizziness as a result of the visual changes and others will develop double vision. Those who are developing cataracts will also have a tendency to change eye glass prescription quite often, or more often than is usual, and the eyes may be very sensitive to light, glare, reflective surfaces, all of which can make driving at night very difficult, if not impossible, to do. Upon inspection some or all of the lens of the eye will appear to be cloudy, white, or even yellowish in color. When compared with a normal lens, the differences will be quite obvious.
