The eyes A close up of a young person's eyes. The eyes are responsible for four-fifths of all the information our brain receives. Here you can find out a bit more about how they work, common problems that affect vision and the work Sightsavers does to treat and prevent avoidable blindness. You can also find out more about the people whose lives have been changed thanks to donations from people like you. How do eyes work? (click image to see enlarged version or click here for text alternative) Graphic of an eye with information about its different parts The images we see are made up of light reflected from the objects we look at. This light enters the eye through the cornea. Because this part of the eye is curved, it bends the light, creating an upside down image on the retina (this is eventually put the right way up by the brain). The retina is a complex part of the eye, but only the very back of it is light sensitive. This part of the retina has roughly the area of a 10p coin, and is packed with photosensitive cells called rods and cones. Cones are the cells responsible for daylight vision. There are three kinds – each responding to a different wavelength of light: red, green and blue. The cones allow us to see images in colour and detail. Rods are responsible for night vision. They are sensitive to light but not to colour. In darkness, the cones do not function at all. How do we see an image? The lens focuses the image. It can do this because it is adjustable – using muscles to change shape and help us focus on objects at different distances. The automatic focusing of the lens is a reflex response and is not controlled by the brain. Once the image is clearly focused on the sensitive part of the retina, energy in the light that makes up that image creates an electrical signal. Nerve impulses can then carry information about that image to the brain through the optic nerve.

The average human digestive tract is home to as many as 1,000 species of microorganisms. Most of them are harmless -- or even helpful -- under normal circumstances. But when something upsets the balance of these organisms in your gut, otherwise harmless bacteria can grow out of control and make you sick. One of the worst offenders is a bacterium called Clostridium difficile(C. difficile, or C. diff). As the bacteria overgrow they release toxins that attack the lining of the intestines, causing a condition called Clostridium difficilecolitis.

Pulsatile Tinnitus Cure, Constant Ear Ringing, Ear Wax Tinnitus, Whistling In Ear, Ringing In Ears. http://tinnitus-solution.info-pro.co First the good news - we know what causes tinnitus. And now the bad news - conventional medical science cannot cure it. Not permanently at least. Sure enough, your doctor would suggest a few remedies, and it may seem to you that the noises you hear are going down. As a result, you begin to relax believing that a pesky problem has been resolved. But suddenly the sounds return again. This is a very common problem actually. So let us turn to the causes instead, and see whether we can try to solve the issue from this end. Here Are Some of the Most Common Causes of Tinnitus Exposure to noise - Did your mom always tell you in your younger days to turn down the volume? She was right. Exposure to loud noise can give you tinnitus. In fact, rock musicians, and those who work with them, or in night clubs often have it. Those who work in construction sites also have tinnitus. So turn down that volume while you still can. You could begin to hear all kinds of noises if you have been exposed to just a single high-pitched noise. Or it could be due to a continuous attack of loud noises close to your ear. This is what happens. Prolonged exposure to noise can damage the Cochlea and cause tinnitus. So if you cannot simply stay away from all that noise, at least get some protection. Use an ear plug when you can. Head injury - Take care of your head because a severe blow or a slight bang could make you hear the tinnitus noises. The head is of course one of the most sensitive parts of the human body. But some people cannot live without an injury, such as those who are into sports - boxers and football players. That's why athletes are more prone to a tinnitus attack. Even a dental surgery could make you hear them. Ear infections and other ear problems - An ear infection, and even sinus can lead to tinnitus as well. When there is an allergy or a sinus infection, the mucous thickens within the inner ear, and this causes more pressure. The extra pressure can lead to tinnitus. Meniere's disease, where the fluid level goes up inside the middle ear is another reason. It could even cause hearing loss. Prescription medications - Conventional drugs often cause side effects, and tinnitus is one of them. Actually, all kinds of drugs have been blamed for instigating this condition. Such as antibiotics like Aminoglycosides, Erythromycin and Vancomycin, Aspirin or medicines containing it. Anti inflammatory drugs like Advil, Aleve, Anaprox, Clinoril, Feldene, Indocin, Lodine and Motrin have also been blamed. Sometimes people heard noises after taking chemotherapy agents such as Cisplatin, Nitrogen Mustard and Vincristine. And some others have even blamed quinine and loop diuretics for this. or even the result of a virus or infection. but is in fact far more shocking that you’ve been led to believe. You’ll finally be able to concentrate on your life, rather that the incessant noise. You’ll be able to no longer live in fear of loud noises, of music, of cinemas. of having fun.
