How to Identify Symptoms of Cataracts

Cataracts are a condition caused by a clouding of the lens of the eye that may take months or years to develop. Generally caused by age, they also form due to complications of diabetes such as high blood sugar. They may also be caused by chronic eye disease, prolonged exposure to bright sunlight and radiation. In some cases, cataracts may be genetic. Smoking has been known to heighten the risk of developing cataracts. Cataracts are formed when proteins clump together and cloud small portions of the lens, which worsen with time. While most people suffering from cataracts are over 60 years old, it may affect newborns born with congenital defects as well. Understanding the signs and symptoms of cataract formation may provide quick and more effective treatment.

Instructions

Difficulty: Moderately Easy

1. Note if you have blurred or cloudy vision that may be more noticeable when exposed to bright lights. In most cases, people suffering from cataract development notice a difference in their night vision, especially when driving. In such cases, oncoming lights, streetlights and lamps seem to take on the appearance of halos.
2. Notice if you experience a decreased ability to read. It may be accompanied by an inability to notice color differention.
3. Note the appearance of a milky or white film over the pupil, which signified an advanced stage of the condition. At this point, many people experience double vision as well.
4. Cataracts that form in one eye may differ from one that forms in both eyes, so people suffering from cataracts may notice a change of vision that differ between eyes.
5. A person suffering from the early stages of cataracts may notice that they need to have their prescription eyeglasses changed more frequently.

Tips & Warnings

• Carefully note any changes to vision and visit an ophthalmologist. Treatments may depend on the severity of the cataract formation, but surgery is most often the preferred treatment. Wear protective sunglasses and don't drive at night if your night vision has been affected.
• Loss of vision may occur if cataracts are not removed.
