According to All About Vision, mounting research is proving that reaching the recommended daily intake of antioxidants, omega-3 fatty acids and micronutrients can help prevent the development of symptoms caused by many eye diseases. Some eye care providers are even recommending higher intake of specific eye supplements and vitamins for patients who are at risk for eye disease. While the following guide will provide you with information about the nutrients and recommended daily amounts if applicable, it is essential to discuss these supplements with your eye care provider as complications can arise from taking too much of some, or conflict with medications you may be taking.
— May aid in preventing dry eyes and night blindness — Sources: liver, milk eggs and butter — Daily recommendation is 55 mcg
— Thought to reduce the risk of age-related macular degeneration (AMD) and cataracts — Sources: broccoli, kale, strawberries and oranges — Daily recommendation is 90 mg for men and 70 mg for women
Cataracts are the leading cause of blindness throughout the world, according to Prevent Blindness America. With more than 24 million people over 40 suffering from cataracts in the U.S. alone, Prevent Blindness America has declared June as Cataract Awareness Month. Because cataract surgery has a success rate of roughly 95 percent, education on the causes of cataracts, symptoms and treatment options can limit the numbers of people blinded by this affliction.
The lens of the eye is composed of mostly water and protein. A healthy lens is clear and allows light to pass through the eye to the retina where it signals the brain and ultimately translates into familiar images. Cataracts cause the lens to become cloudy, subsequently affecting the clarity of the images, or impairing vision completely.
More than 50 percent of Americans over the age of 80 will have cataracts or will have undergone cataract surgery, making age the most common cause of cataracts. This is because the protein that helps form the lens breaks down over time and begins to affect vision. Other causes of cataracts may include:
It is no secret that the aging process can affect vision, even in people who have not previously had any issues. You may find yourself squinting to see things in the distance, or holding your reading material closer to your face to see clearly. While you may be hesitant to see your eye care provider, regular comprehensive eye exams are more important at this stage of your life than ever. There are several eye conditions in seniors that can rob you of your sight before you even realize you have a problem.
Independence is critical to leading a full life and your vision plays a large role in sustaining it, especially as you age. While a healthy diet and exercise, as well as not smoking or drinking in excess, contribute to healthy vision, maintaining a schedule for comprehensive eye exams is one of the most important things you can do for yourself. According to the American Optometric Association, there are eye conditions, especially in those 60 and older, in seniors that can permanently affect your vision, and by the time you do feel there is a problem, the damage is often irreversible. Some of these conditions include:
While the feeling of dry eyes, for many, is not a regular occurrence, it is a chronic condition for some and can cause permanent damage to the eye if not properly diagnosed and treated by an eye health practitioner. The following will discuss some dry eye symptoms and treatment that can help alleviate the discomfort.
In order to understand dry eye symptoms and treatment, a basic understanding of the underlying cause is essential. As you are likely aware, tears are the natural lubricants for your eyes. They are a complex mixture of oils, water and mucous that stop your eyes from drying out and help bathe away small particles that may irritate the eyes.
According to the National Eye Institute, chronic dry eye occurs when the eyes are not producing enough of the watery portion or tears, or not enough of the oils that keep tears from evaporating too quickly. Since the health the outer layer that covers the colored part of your eye (cornea) depends on keeping your eyes properly lubricated, chronic dry eye can cause permanent damage and potentially affect your vision. The following are some symptoms you may experience:
Age-related cataract development is one of the leading causes of blindness world wide, according to All About Vision. Characterized by a clouding of the lens in the eye, currently the only treatment to restore vision is surgical removal of the natural lens and replacing it with an artificial one. While the surgery is usually successful, research is showing some important links between diet and cataract prevention.
The general thought is cataracts form due to the breakdown of healthy cells that create the lens of the eye during the regular metabolic process that leads to cell-aging. Also known as oxidative stress, cells become damaged when there is not an ample oxygen ratio in our bodies. An excess of oxygen can turn this life-sustaining gas into free radicals that work to destroy healthy cells. For optimum cell reproduction, the more antioxidant-rich nutrients we digest the less unused oxygen will remain which will result in fewer cell-damaging free radicals.
With the concept of oxidative stress in mind, research is growing in the area of diet and cataract prevention. According to All About Vistion, in most of the studies conducted, positive results for a reduction or slowed progression of cataracts were found in those who had a …
As an autoimmune and inflammatory disease, Crohn’s disease also causes complications in the eyes of 10 percent of those who suffer from the disease, according to Everyday Health. In fact, the chief medical officer of Bausch & Lomb, Dr. Calvin Roberts, suggests being tested for Crohn’s if you experience eye inflammation repeatedly. If your eyes are not affected directly by your Crohn’s disease, it is possible to experience eye diseases due to the medications used in your treatment.
Oral steroids are often prescribed to treat Crohn’s and have been known to cause conditions such as high eye pressure, glaucoma and cataracts. Here are the four most common eye diseases that affect Crohn’s disease patients:
Uveitis The uvea is inside of your eye and is rich in blood vessels that supply nutrition to your cornea, lens, iris and retina. Uveitis is when this lining becomes swollen due to inflammation and causes the retina to swell. The swelling causes blurry vision which may occur suddenly, or over a period of time. Left untreated, uveitis can lead to glaucoma and ultimately, vision loss. Due to the inflammatory nature of Crohn’s, uveitis is the most common of eye diseases associated with the illness.
