Cataracts – what’s new?

Cataracts can not only be prevented, but can even be reversed through nutrition, supplementation and lifestyle changes. Read what folks who’ve tried these methods say about products that help cataracts and learn about products to support lens health. Cataracts – once considered an inevitability for the elderly and sometimes not-so-elderly, redeemable only by surgery. There’s been quite a bit of interesting new research in the last several years pointing to the alternatives and effects of different modes of living that have an impact. 1. 2008 – An observational 10-year study of more than 35,000 middle-aged U.S. women observed the women’s use of dietary supplements and occurrence of cataracts – further verifying that lutein, zeaxanthin and vitamin E were significantly helpful. 2. 2006 – Two studies show significant reductions in cataracts for those in the highest percentage of vitamin C & bioflavonoids intake. 3. 2007 – Dietary linolenic acid (think flaxseed oil, fish oil) intake is positively associated with five-year change in eye lens nuclear density (think cataracts!). Causes?
  • Free radicals are responsible for most cataracts. They are natural byproducts of metabolism. These highly reactive chemicals cause oxidation, which in turn causes aging. As the lens of the eye ages, it hardens and loses its ability to focus. This process is similar to hardening of the arteries, and is often associated with changes in the joints.
  • Chronic physical stress such as dental problems, physical injury to the vertebrae or neck, or any stress that reduces eye movement and increases muscle tension.
  • Food Allergies or sensitivities, particularly involving dairy products, wheat and/or soy can congest the sinuses, impairing lymphatic and veinous drainage, resulting in decreased nutrition to the eyes.
  • Toxins, pharmaceutical drug side effects, such as steroid drugs, or photosensitizing drugs such as gout medications, cholesterol lowering drugs, antibiotics and diuretics.
  • Smoking – the risk in ex-smokers is 50 percent higher compared to non smokers. Each cigarette also robs the body of 25 mg of vitamin C. Smokers have an increase in lipids (both fat and cholesterol) which increase the risk of severe cardiovascular disease. These factors produce narrowing of the retina blood vessels that carry valuable nutrients to the eye.
  • Diabetes and other diseases that affect multiple areas of the body such as hypertension, arthritis, heart disease, and diabetes. Diabetics develop cataracts at an earlier age than non- diabetics. An accumulation of sorbitol and fructose in the lens can induce osmotic swelling of the lens, which will lead to the development of a cataract.
  • Poor nutrition and digestion. Nutritional deficiencies, such as in poor areas of Third World countries, can cause cataracts to develop early and progress faster. In every part of the world, people with poor digestion and chronic bowel problems have a fourfold higher incidence of cataracts.
  • Heredity
  • Aging of the Eyes – hardening of the lens occurs as we age.
  • Sunlight – invisible ultraviolet light (UV light) which is one of the light frequencies of sunlight promotes free-radical damage to the lens. The effects of UV light are cumulative over time.
  • Alcoholic Consumption – High intake of alcohol more than doubles the risk of developing cataracts. More than 7 drinks per week will increase the risk, while moderate use does not seem to increase the risk.
  • Too much Vitamin B2 aggravates – Those with Cataracts should not use supplemental Vitamin B2. Vitamin B2 is a photosensitizing substance – experimental studies have shown that when Vitamin B2 is exposed to Visible Light, Cataracts can occur (or be exacerbated) as a result of the generation of Free Radicals from the interaction of Visible Light, Oxygen and Vitamin B2. This indicates that in persons afflicted with Cataracts, excessive Vitamin B2 is more harmful than beneficial. .

I Spy a Stye in Your Eye

Image
Written by Dr. David Evans Last modified on August 6, 2018 What’s that small, red, pimple-like bump on your eyelid that’s causing so much discomfort? It’s probably a stye (sometimes referred to as a sty or hordeolum). Besides being difficult to say 5 times quickly, an eye stye is a type of localized infection that can occur along the base of your eyelashes or underneath your eyelid. Styes that form along the base of the eyelashes are called external styes. They typically occur as a result of an infected eyelash hair follicle and look like the type of pimple that occurs when your pores are clogged with dirt and oil. Styes that form inside the eyelid are called internal styes. Similar to external styes, they are caused by an infection of an oil-producing gland behind the eyelid rather than an eyelash hair follicle. Internal styes result in generalized swelling of the eyelid rather than forming a pimple-like bump. Stye Symptoms As a stye develops, you might begin to experience pain

Post-LASIK Refraction and Pregnancy – Much Ado About Nothing?

Image
Written by Dr. David Evans Last modified on August 23, 2018 During pregnancy, women experience a drastic shift in their hormonal balance that has a ripple effect throughout the body. The spike in hormones like progesterone, estrogen, prolactin, oxytocin and relaxin are all important for a healthy pregnancy, but these increased levels can also impact gastrointestinal processes, blood pressure, skin pigmentation and, you guessed it, ocular health. Due to refractive changes that often occur during pregnancy, most refractive surgeons advise against LASIK during pregnancy, instead suggesting women wait several months after giving birth before considering treatment. Women who have already undergone LASIK may then wonder if the changes in ocular health that can occur during and after pregnancy impact post-LASIK refraction. New research presented by John Kanellopoulos, MD, New York University Medical School, NY, and LaserVision.gr seems to throw cold water on any such concern. The Eyes an

Overuse of Contact Lenses

Image
How do make sure you aren’t overusing your lenses? Most people who have prescription eye glasses prefer wearing contact lenses. It’s not only comfortable but it also doesn’t alter your natural look. Though contact lenses are convenient they shouldn’t be used extensively. Overuse of contact lenses can cause serious damages to your eye. If you are not following the 18 hour week rule, then you could be overusing your contact lenses. In other words you must take out your contact lenses for at least 18 hours a week. Here are some symptoms which are indications that you are using you have your lenses on longer than you should, and you need to consult your eye doctor immediately: Pain and redness in the eye Itching when you remove your lenses Increased mucous secretion in the eye Decreased vision Photophobia or light sensitivity Tearing Inability to remove your lenses because they are stuck in the eye   Your eye needs direct oxygen to ‘breathe’ and remain healthy.
