Information About Cataracts

Having one’s vision is extremely important to people as they love and enjoy being able to see things. This is why it is essential to have regular eye exam every year to rule out any possible eye issues, such as cataracts, which do happen to people for different reasons.

Cataracts are defined as the eyes’ lens being cloudy, causing difficulty for the person to see clearly. What causes the cloudiness in the lens is when the lens fall apart. Other symptoms of this condition are intolerance to bright lights shining into eyes, seeing things in twos, uneasiness seeing in the dark or in a dim-lighted area, and seeing circles around lights (looks like a halo around lights).


People do not necessarily know that a cataract is developing in one of their eyes or both because the progress is gradual and it does not hurt at all. People will just starting to have blurry visions and cannot explain the reason for that happening. There are things that prompt the onset of this condition, such as:
• Diabetes
• Eye inflammation
• Eye injury
• Family history
• When one took corticosteroids for a long period of time
• Being exposed to radiation
• Smoking
• Have had eye surgery for different reason
• Overexposure to sunlight.
Even though the above-mentioned may start the problem, for most people, there is no known cause for this condition.

There are three kinds of cataracts; Subcapsular, Nuclear, and Cortical. Subcapsular tends to start in the back of the lens. People that are most likely to get this kind are those who are diabetic, that have high farsightedness as well as retinitis pigmentosa, or who took steroid medications in high doses. Older people’s lens’ nucleus (the main area) becomes affected, which causes them to develop Nuclear cataract. The Cortical type happens when the lens’ cortex that envelopes the nucleus goes haywire.


Having this condition does not necessarily mean the end of having a sight because it is treatable via cataract surgery and lens implant. Most people who had the surgery end up having an Intraocular Lens Implant (IOL), which fixes the vision to ensure that the patient is able to see again. Because cataract surgery is commonly covered by private insurance or Medicare, it is done often in the United States because of low/affordable cataract surgery cost. Not only that, people having the surgery needs not to worry because it is often foolproof and successful.
