Cataract Symptoms: Cloudy, Blurry Vision and Other Eyesight Changes
 A cataract is a cloudy portion of the lens of the eye. Symptoms usually progress slowly, but occasionally, a cataract causes no symptoms whatsoever. One of the first signs of a cataract is a slight, yet bothersome, blurring of vision. Sunlight and indoor lights may seem too bright or intense, and when you are driving at night, you may notice that oncoming headlights create more glare than usual. Cataract symptoms generally affect people over the age of 65, but these symptoms can develop in younger people.
Classic cataract symptoms can include:
- Cloudy, blurry, foggy, or filmy vision
- Poor vision at night
- Problems with glare
- Sensitivity to light
- Double vision (usually in one eye)
- Needing brighter light to read
- Sudden temporary improvement in close-up vision
- A need for changes in eyeglass prescription
- Sudden nearsightedness
Also, cataracts tend to develop symmetrically, that is, they usually develop in both eyes at the same time. If you are experiencing cataract symptoms, contact an ophthalmologist immediately. He will perform vision tests to make a definitive diagnosis and to prescribe a treatment plan. Depending on the severity of your condition, cataract treatment can be as simple as changing your eyeglass prescription or as intensive as surgical procedures to replace a cloudy lens with an artificial one.
Little is known about preventative measures for cataract symptoms, but it is believed that nutrients and supplements may help improve overall eye health and lower your risk of developing cataracts and glaucoma. One such nutrient is lutein, which is found in green, leafy vegetables, and egg yolks. The antioxidant glutathione is also linked to improved eye health. These substances are also available as supplements if you can't get enough in your diet. Before beginning any preventive or treatment measures, you may want to consult with a medical professional, who can help you optimize your plan for success.
