Genetics is the most common cause of vision problems, while eye damage is caused by overuse, trauma, and disease. Nearsightedness and farsightedness are often related to family history, while glaucoma and cataracts are usually caused by aging. Minor vision problems can be caused by basic factors such as lack of sleep or dirty contact lenses.
The most common cause of vision problems is probably genetics. Some people are simply more prone to eye problems than others. Eye damage, on the other hand, is commonly caused by overuse, trauma, and disease. Depending on the problem, the condition could be linked to any number of causes, so it’s a good idea to understand the specific components of vision problems before seeking a diagnosis. Once the problem has been identified further, the causes can be identified more easily.
People who are nearsighted or farsighted often have a family member with the disorder. Nearsightedness, sometimes called myopia, is usually related to family history but can sometimes be attributed to long-term use of a computer or performing other close-up work. Farsightedness, or farsightedness, is also usually related to family history, but can start later in life as a result of aging.
Vision problems such as glaucoma are usually caused by fluids not draining from the eye. This drainage failure is sometimes related to a specific disorder, such as diabetes or cancer, but it is just as often related to old age. Similarly, vision problems such as cataracts can be caused by disease, but are usually a result of aging. Cataracts are the result of protein breakdown in the eye, but when these vision problems are caused by exposure to ultraviolet light, smoking or steroid use, they can occur even at a young age.
Sometimes vision problems can be caused by trauma to the eye. A black eye, for example, can disturb your vision, as can an eye infection. Sometimes the problem is as simple as flashing or blurry vision. When the trauma is severe, vision in the affected eye can be completely lost. It is important to thoroughly investigate any vision problems related to the trauma because the problem could be in the brain, not specifically in the eyes.
In addition to these more serious vision problems, many people experience minor vision problems from very basic causes. Being awake for too long, for example, can cause vision to blur, and dirty or old contact lenses can cause vision distortion. Allergies often cause dry eyes, as does pregnancy for some people, and sometimes dust or other irritants in the air can make your eyes water. Before investigating the rarer causes of these very basic and fairly harmless vision problems, it’s a good idea to rule out the obvious causes first.
