What are the most common causes of sight?

The most common cause of vision problems is probably genetics. Some people are simply more susceptible than others to eye problems. On the other hand, eye damage is usually caused by excessive use, trauma and disease. Depending on the problem, the failure could be associated with any number of causes, so it is good to find out specific eye problems before you seek a diagnosis. Once the problem is further identified, the causes can be easier to identify. The nearsightedness, sometimes called myopia, is usually related to family history, but sometimes it is possible to attribute long -term use of a computer or perform other detailed work. Frequentness or hyperopia is also usually related to family history, but may start later in life as a result of aging.

Problems such as glaucoma are usually caused by fluids in the failure of the eye. This failure of drain is sometimes related to a specific disorder such as diabetes or tumors, but is equally related to age. SimilarlyEye problems such as cataracts can be caused by diseases, but are usually the effect of aging. Cataracts are the result of degradation of proteins in the eye, but when these eyesight problems are caused by exposure to ultraviolet light, smoking or using steroids, they can also occur at a young age.

Sometimes the eye problems can be caused by trauma into the eye. For example, the black eye can disrupt vision as well as eye infection. Sometimes the problem is as simple as blinking or blurry vision. When trauma is serious, the eyes on the affected eye can be completely lost. It is important to thoroughly examine any trauma -related vision, as the problem may be in the brain, not specifically in the eye.

In addition to these more serious vision problems, many people have minor vision problems for very basic causes. For example, upwards for excessive time can cause blur and wPinhable or old contact lenses can cause vision distortion. Allergies often lead to dry eyes, as well as pregnancy in some people, and sometimes dust or other irritating substances in the air can cause water eyes. Before examining the rare causes of these very basic, relatively harmless visual problems, it is good to exclude obvious causes first.
