Blepharitis is the medical term for inflammation of the eyelids. The word "blepharitis" is derived from the Greek wordblepharos, which means "eyelid," and the Greek suffixitis, which is typically used to denote an inflammation in English. Inflammation is a general term used to describe the process by which white blood cells and chemicals produced in the body protect us from foreign substances, injury, or infection. The normal body response of inflammation involves varying degrees of swelling, redness, pain, warmth, and change in function. Blepharitis is an inflammation of the eyelids, causing red, irritated, itchy eyelids, and the formation of dandruff-like scales on the eyelashes. It is a very common eye disorder with a wide variety of causes. It affects people of all ages. Although it may be uncomfortable, annoying, or unattractive, blepharitis is not contagious and generally does not cause any permanent damage to eyesight. The condition can be difficult to manage because it tends to recur. Another term for blepharitis is granulated eyelids. Angular blepharitis is a term used to describe blepharitis which primarily affects the outer corners of the eyelids. Read on another eye disease KERATOCONUS

What is Keratoconus ?

We see through the cornea, which is the clear outer lens or "windshield" of the eye. Normally, the cornea has a dome shape, like a ball. Sometimes, however, the structure of the cornea is just not strong enough to hold this round shape and the cornea bulges outward like a cone. This condition is called keratoconus. What Causes Keratoconus? Tiny fibers of protein in the eye called collagenhelp hold the cornea in place and keep it from bulging. When these fibers become weak, they cannot hold the shape and the cornea becomes progressively more cone shaped. Keratoconus is caused by a decrease in protective antioxidants in the cornea. The cornea cells produce damaging by-products, like exhaust from a car. Normally, antioxidants get rid of them and protect the collagen fibers. If antioxidants levels are low, the collagen weakens and the cornea bulges out. Keratoconusappears to run in families. If you have it and have children, it’s a good idea to have their eyes checked for it starting at age 10. The condition progresses more rapidly in people with certain medical problems, including certain allergic conditions. It could be related to chronic eye rubbing. Keratoconus usually starts in the teenage years. It can, though, begin in childhood or in people up to about age 30. It's possible it can occur in people 40 and older, but that is less common. The changes in the shape of the cornea can happen quickly or may occur over several years. The changes can result in blurred vision, glare and halosat night, and the streaking of lights. The changes can stop at any time, or they can continue for decades. There is no way to predict how it will progress. In most people who have keratoconus, both eyes are eventually affected, although not always to the same extent. It usually develops in one eye first and then later in the other eye. With severe keratoconus, the stretched collagen fibers can lead to severe scarring. If the back of the cornea tears, it can swell and take many months for the swelling to go away. This often causes a large corneal scar.We see through the cornea, which is the clear outer lens or "windshield" of the eye. Normally, the cornea has a dome shape, like a ball.

KEY TO OPTIMUM HEALTH [KEY 3]

Key 3—Keep Yourself Moving “If exercise were a pill, it would be the most widely prescribed medication in the world.” (Emory University School of Medicine) Of all the things we can do for our health, few are more generally helpful than physical exercise. Exert yourself.Leading a physically active life can help us feel happier, think more clearly, have more energy, be more productive and, along with proper diet, control our weight. Exercise need not be painful or extreme to be effective. Regular periods of moderate exercise several times a week can be very beneficial. Jogging, brisk walking, biking, and taking part in active sports—enough both to get your heart beating faster and to cause you to break a sweat—can improve your endurance and help to prevent heart attack and stroke. Combining such aerobic exercise with moderate weight training and calisthenics helps to strengthen your bones, internal muscles, and limbs. These activities also contribute to maintaining a higher metabolism, which automatically helps to control your weight. Exercise can be enjoyable Use your feet.Exercise is beneficial for people of all ages, and membership in a gym is not required to get it. Simply using your feet instead of a car, bus, or elevator is a good start. Why wait for a ride when you can walk to your destination, perhaps even arriving there faster? Parents, encourage your children to participate in physical play, outdoors whenever possible. Such activity strengthens their bodies and helps them to develop whole-body coordination in ways that sedentary entertainment, such as video games, cannot. No matter how old you are when you start, you can benefit from moderate physical exercise. If you are older or have health problems and have not been exercising, it is wise to consult a doctor about how to begin. But do begin! Exercise that is started gradually and not overdone can help even the oldest among us to maintain muscle strength and bone mass. It can also help seniors to avoid falls. Exercise is what helped Rustam, mentioned in the first article of this series. Seven years ago, he and his wife began jogging a little each morning, five days a week. “At first, we made excuses not to go,” he relates. “But having a partner helped to motivate both of us. Now it has become a good, enjoyable habit.”

Key To Optimum Health

Key 2—Take Care of Basic Body Needs “No one ever hated his own body: on the contrary, he provides and cares for it.” ( Ephesi ans 5:29,The New English Bible) Taking basic steps to care for yourself can make a world of difference in your health. Get enough rest.“Better is a handful of rest than a double handful of hard work and striving after the wind.” ( Ecclesiast es 4:6) The demands and distractions of modern life have whittled away at the time people spend sleeping. But sleep is essential to good health. Studies show that during sleep our body and brain repair themselves, benefiting memory and mood. Sleep reinforces the immune system and reduces our risk of infection, diabetes, stroke, heart disease, cancer, obesity, depression, and perhaps even Alzheimer’s disease. Rather than artificially bypassing sleepiness—our natural “safety device”—with sweets, caffeine, or other stimulants, we should heed it and simply get some sleep. Most adults need seven to eight hours of sleep every night to look, feel, and perform their best. Young people need more. Sleep-deprived teens are more prone to have psychological troubles and to fall asleep when driving. Sleep is especially important when we are sick. Our body can overcome some illnesses, such as a cold, if we simply get extra sleep and drink plenty of fluids. Take care of your teeth.Brushing your teeth and flossing them after meals, and especially before going to bed, will help ward off tooth decay, gum disease, and tooth loss. Without our own teeth, we may not benefit fully from the food we eat. It is reported that elephants do not die of old age but that they slowly starve to death after their teeth wear down and they can no longer chew properly. Children who have been taught to brush and floss their teeth after eating will enjoy better health in youth and throughout life. Go to the doctor.Some ailments call for professional medical attention. Early diagnosis usually results in a better outcome and less expense. So if you do not feel well, get help to find and eliminate the cause, instead of merely seeking to relieve the symptoms.

KEY TO OPTIMUM HEALTH

Key 1—Eat Wisely “Eat food. Not too much. Mostly plants.” With these few words, author Michael Pollan encapsulates simple, time-tested dietary advice. What does he mean? Eat fresh foods.Concentrate on eating “real” food—whole, fresh foods that people have been enjoying for millenniums—rather than modern processed foods. Commercially prepackaged foods and fast food from chain restaurants usually contain high levels of sugar, salt, and fat, which are associated with heart disease, stroke, cancer, and other serious illnesses. When cooking, try steaming, baking, and broiling instead of frying. Try using more herbs and spices to cut down on salt. Make sure meats are properly cooked, and never eat spoiled food. Do not eat too much.The World Health Organization reports a dangerous worldwide increase in overweight and obese people, often the result of overeating. One study found that in parts of Africa, “there are more children who are overweight than malnourished.” Obese children are at risk of present as well as future health problems, including diabetes. Parents, set a good example for your children by limiting your own portions. Eat mostly plants.A balanced plate favors a variety of fruits, vegetables, and whole grains over meats and starches. Once or twice a week, try substituting fish for meat. Reduce refined foods such as pasta, white bread, and white rice, which have been stripped of much of their nutritional value. But avoid potentially dangerous fad diets. Parents, protect your children’s health by helping them to acquire a taste for foods that are healthful. For example, give them nuts and thoroughly washed fresh fruits and vegetables for snacks instead of chips or candy. Drink plenty of fluids.Adults and children need to drink plenty of water and other unsweetened liquids every day. Drink more of these during hot weather and when doing heavy physical work and exercise. Such liquids aid digestion, cleanse your body of poisons, make for healthier skin, and promote weight loss. They help you to feel and look your best. Avoid drinking excessive amounts of alcohol and too many sweetened drinks. One soft drink a day can add 15 pounds (6.8 kg) to your weight in a year. In some lands, obtaining clean water can be hard work and is expensive. Yet, drinking it is vital. Tainted water needs to be boiled or chemically treated. Dirty water is said to kill more people than wars or earthquakes; it reportedly kills 4,000 children a day. For infants, the World Health Organization recommends only breast-feeding for the first six months, then breast-feeding plus some other foods until at least the age of two.
