Cataract Information, Symptoms & Treatment
Cataracts are the major cause of vision loss in the United States. Symptoms can include blurry, hazy vision that worsens over time as well as sensitivity to glare. Research has shown that treatment in the form of specific lifestyle, diet and supplement choices can support overall lens health. A cataract appears as an opaque spot on the lens of the eye that obstructs vision.
It may seem as though you are looking through a hazy cloud. The density of the cataract typically increases over time so the effect on your vision will vary depending the cataract density and the location of the cataract on the lens.
Depth perception can often be affected resulting in an added risk of falling for seniors. The lens can change as we age and be damaged in several ways. The most common is that with age it becomes less flexible and less able to adjust between near and far distances.
The lens can become clouded, obscuring vision. Damage to the eye's lens impairs vision for driving, close work, color and depth perception. Many other eye conditions and specific medications can lead to lens damage. Patients with impaired lenses may experience blurry or cloudy vision, poor night vision, difficulty in depth and color perception and other symptoms.

Grossman Ask the Practitioner. Damage The lens can change as we age and be damaged in several ways. This is especially true in bright light or glare conditions. We have poor vision at night, making driving dangerous at night. The eye lens may appear cloudy. We find that we need more light to read and that reading is tiring. Our depth perception is not very good. We see halos, especially in bright sunlight. Our glasses always seem dirty, no matter how much we clean them.
Causes Read about the mechanics of cataract formation. Researchers report that free radical damage to the proteins in the lens of the eye are important factors in development of cataracts. Researchers report that nutrient deficiencies play a role in the development of cataracts. Deficient glutathione levels contribute to a weak system of antioxidants. Lipoic acid, vitamins E and C, and selenium support glutathione levels. The by-products of our metabolism of food, cause oxidation, and in turn accelerating aging.
As the lens of the eye ages, it hardens and loses the flexibility needed for focusing. Due to injury to the back or neck, continuing dental pain, or stress that limits movement of the head and eyes and increases tension and tightness in muscles. Allergies and food sensitivities , especially allergies of soy, wheat or dairy products which might give rise to congestion and slow or block circulation of tiny capillaries delivering nutrients to the eye, as well as lymphatic drainage.
People who smoke have a much higher risk of developing cataracts. When you smoke you rob the body of vitamin C a needed nutrient for healthy vision.
Smokers also have more cholesterol and fat in their blood system with more risk of coronary artery disease. This condition also compromises the effectiveness of tiny blood vessels in the eyes - reducing the ability of the different parts of the eye to receive adequate nutrition. Learn more about the relationship between smoking and cataracts. Diabetics form cataracts at a younger age than those who do not suffer from diabetes.
This is due to the build-up of sugar resulting in glycation binding together of sugar and protein molecules. Researchers note that argpyrimidine, a biochemical formed in the presence of sugars, increase in diseased lenses. People with incomplete digestion and ongoing bowel and elimination problems have a four times as many cases. Heredity and advanced age by themselves are risk factors. Heredity and congenital cataracts. Some can be removed surgically; future treatments may include stem cell therapy.
Sunlight includes invisible UV light that accelerates damage to the lens by free radicals. These effects are cumulative. Researchers have pointed out that no amount of sunlight is a safe level for the eyes. More than one drink a day doubles the risk. The World Health organization reports that high body mass index is an indicator of high cataract risk.
Researchers report that inactivity with little exercise increases the risk of cataract. Cataracts can also develop following eye surgery such as a vitrectomy for epiretinal membrane.
Toxins and drug side effects , including steroids and photosensitizers that are found in medicines prescribed for gout and high cholesterol as well as and antibiotics. Drugs which make you more light-sensitive to sunlight cause chemical changes to tissue which, in turn, can make you more vulnerable.
Among the more common photosensitizing drugs: Birth control pills Antihistamines Sulfa drugs Tranquilizers and antidepressants Oral anti-diabetic drugs Glucocorticoids Prednisone Cataracts will form in half of the people who take doses of milligrams prednisone daily over years.
Steroids Cataracts caused by steroids are dense and can cause rapid vision loss. They will not go away when medication is stopped and have to be removed surgically. If you must take steroids, be sure to get plenty of antioxidants such as lutein, alpha lipoic acid, vitamin E, and vitamin C for prevention.
Etretinate, isotretinoin Related Conditions Cataracts can be related to other conditions because they increase the risk of other conditions.
Cataracts can also be related to others because the other conditions make the risk of cataracts greater.
