Cataracts

Cured Cataracts

 

Many people are familiar with the cloudy appearance of an eye affected by a cataract. Still, the underlying causes of this condition and proper treatments are not as well known. First, it is important to know what a cataract is. A cataract is the clouding of the lens. This lens is situated behind the iris. With the presence of a cataract often comes decreased vision capabilities. Though they often develop slowly and with little impact on your vision at first, cataracts are a progressive condition that can become increasingly impairing over time.

Cataracts are common in the elderly, with close to eighteen million elderly worldwide affected by cataracts and age-related-cataracts accounting for nearly half of all the cases of blindness in the world. It is important to note that cataracts are not exclusive to the elderly population, and it is a condition that can affect a person at any age. While cataracts affect the eye, they are just one component of a person's overall physical health.

Non-optical conditions such as hypertension and diabetes can spur the development of a cataract. Environmental factors that can promote the development of cataracts include continuous exposure to ultra-violet light, radiation exposure, eye trauma, and genetic factors. There are a number of symptoms associated with the onset of a cataract. The primary symptom of a cataract is vision loss or double vision, especially at night, and what is commonly referred to as a "halo effect" around street lights. A thin, cloudy veil can be noticed over the affected eye. If any of these symptoms are experienced, or if you suspect you are experiencing a cataract, it is imperative to visit your physician. Solutions to cataracts range from vision correcting lenses to manage sight to surgical removal of the cataract.

 

The Development of a Cataract

The lens focuses on the rays that go into the eyes. This help to create images on the retina. The retina is the membrane that functions like the film in a camera. As you grow older, the lenses in the eyes become thicker, less transparent, and less flexible. Some medication conditions related to age cause the fibers and proteins within the lenses to completely break down and clump together. These clumps cloud the lenses of the eyes. As the disorder begins to start, the clouding becomes a lot deeper. The cataract scatters and blocks a lot of the light that passes through the lens. This prevents a sharply defined image from coming into your retina. As an outcome, the vision becomes quite blurred. Cataracts usually develop in both eyes. But this does not happen at the same rate. A single eye's cataract may become more advanced than the other eye. This may lead to a major difference in vision between the eyes.

 

Kinds of Cataracts

There are various types of this disorder that exist. One of these is the one that affects the center of the lens. This may cause a lot more near-sightedness or even temporary improvement in the vision required for reading. But with time, the lens typically turns into dense yellow and clouds the vision. The lens may even become brown as the cataract advances even more. The advanced browning or yellowing of the lens can cause complexity in differentiating between the shades of color. The second type of cataract is the one that affects the edges of the lenses of the eyes. This is known as cortical cataract. It starts as wedge-shaped streaks or opacities on the outer edge of the cortex of the lens. As it keeps moving forward, the streak goes to the center and interferes with the light that passes through the center of the lens.

There is another variant of this disorder. It develops on the back of the lens. This type of disorder often interferes with the overall reading vision. This decreases the vision in bright light. This causes a lot of halos and glare around lights at night. These kinds of cataracts tend to develop a lot faster than the other kinds do. There are also some kinds of cataracts that you are born it. Several individuals are born with this disorder or get it during their childhood. This may happen because of trauma, an intrauterine infection, or genes. This variant may happen because of rubella, galactosaemic, or myotonic dystrophy. Congenital cataracts do not adversely affect the vision in all cases. But they are typically removed soon after detection if they cause some effects.

 

Prevention of Cataracts

There have been no studies that show how to completely prevent this disease or slow its progression. But healthcare providers have suggested some helpful tips. One of these is to go through regular eye examinations. These tests can assist in finding out about cataracts and other eye-related problems at their beginning. Ask your healthcare provider how often you should go through an eye test. Another thing to keep in mind is to quit smoking. You should ask your healthcare provider for tips on stopping smoking. Strategies such as counseling and medications are available to assist you in quitting. You should also try to manage your other health issues. You should follow your treatment plan if you have any medical conditions such as diabetes that can increase your risk of getting cataracts. Finally, opt for a healthy diet that has lots of vegetables and fruits.

 

Conclusion

Cataracts are a disease that develops slowly over time due to various factors. You should undertake periodic eye tests to keep the disease at bay. Also, try to make an appointment for an eye test if you get any changes in your vision. These include sudden headaches, eye pain, flashes of light, or double vision. At this juncture, you should try to consult your healthcare provider immediately.
