Eyes Problems And Diseases

Eyes Problems And Diseases Related Information:

It’s important to know about the different kinds of eye problems and diseases that you could encounter at some point in time. Here, you’ll find a list of some of the most common problems, and some of the most important information relating to them, such as indicators, descriptions, levels of seriousness and treatment, among others. It’s always a good idea to consult you local eye doctor if you think that there may be a serious problem, and especially if you haven’t had an eye exam in a while.

Astigmatism:

The world's most common vision problem is astigmatism. It can come with farsightedness or nearsightedness and is caused by an irregularly shaped cornea. A small amount of astigmatism may not be noticeable or you may notice slightly blurred vision. Astigmatism is caused when the cornea is shaped more like a football than a baseball, which is its normal shape. Many people are born with this football shaped cornea, and the resulting vision problem may get even worse over time.

Blindness:

Many people become blind each year. Half of all blind people are generally over sixty-five. There are also large numbers of children and young adults who are blind. Some of the major causes of blindness include cataracts, diabetic retinopathy and glaucoma.

Color Blindness:

This occurs when you have difficulty distinguishing between red, green, blue and yellow. Red- green color deficiency is the most common type of color blindness. A less common form is blue- yellow color deficiency. Color blindness occurs when certain cells in the retina respond to colors that do not respond back as they should. People with a color deficiency are usually born with it, and the problem affects more men than it does women.

Diabetic Retinopathy:

If you are a diabetic, you probably know that your body cannot store or use sugar properly. When your blood sugar gets too excessive, it may damage the blood in your eyes. This damage can lead to diabetic retinopathy. In later periods, the disease can lead to new blood vessel growth over the retina. The new blood vessels may cause scar tissue to arise, which can then pull the retina away from the back of the eye. This is known as retinal detachment, and can sometimes lead to blindness if untreated. In addition, irregular blood vessels can grow on the iris, which can lead to glaucoma.

Glaucoma:

This is the second leading cause of blindness in the United States. Glaucoma affects around three million Americans, and because of this disease, 120,000 people have gone blind. Around the world, there is very little treatment; therefore glaucoma is a leading cause of blindness. Even if people with glaucoma do not become blind, their vision can be severely impaired. There is pressure in your eye just like there is pressure in your blood and when this pressure increases to dangerous levels, it can cause damage to the optic nerve. This damage can result in a decrease in peripheral vision and eventually cause blindness. Glaucoma is similar to ocular hypertension but is accompanied by optic nerve damage and vision loss.

Hyperopia:

A common vision problem is hyperopia or farsightedness. This condition affects about one-fourth of the population. People who have hyperopia can see objects that are far away very well, but have trouble making out things that are close up. People who are affected by farsightedness might occasionally have headaches or eyestrain and might squint or feel tired when doing something that is close up. Hyperopia occurs when light rays coming into the eye focus behind the retina instead of straight on it. A farsighted person’s eyeball is actually shorter than the average person. Many children are born with this condition but outgrow it as they get older.

Myopia:

One-third of the population experiences the vision defect nearsightedness, or myopia. People who have myopia have trouble making things out that are at a distance, such as highway signs, but they can see and do activities that are close up, such as reading. People who have nearsightedness frequently have headaches or eyestrain. They might also squint or feel weary when driving or playing sports.

As you can see, there are many potential problems that you may encounter, with respect to your eyes, which is one of the reasons why it’s a good idea to keep regular check-up appointments with your local eye doctor. You can learn more about your eyes on the internet and by visiting your local doctor. Studies in eyewear and disease prevention have been helpful for many people who are concerned about their vision.
