Many people want to know what causes cataracts. There are many different factors that can lead to a cataract. In a nutshell, cataracts are caused by the changing of lens tissue in the eye. In other cases, the problem could be hereditary. In order to determine what causes cataracts, family history, habits, age, and health must all be considered.
Age and Eye Sight
Age is often cited as one of the most common causes of cataracts. As we grow older, the eye tissue changes as well. This gradual process can begin as foggy or blurred vision and will become worse over time. There may not be much an individual can do to avoid age related cataracts, however many choose to undergo surgery to restore eye sight.
Health Conditions
If you want to know what causes cataracts, it is also important to look at other health conditions that might be present in the patient. Diabetes has been linked to the formation of cataracts. Individuals who have had an eye injury or surgery may also be susceptible to this common problem. Patients who are prescribed steroids for other health conditions may also be at a greater risk to develop cataracts. Family history can also indicate a hereditary risk.
Habits and the Environment
Habits and the environments we expose ourselves to can also lead to cataracts. In order to determine what causes cataracts in these situations, certain factors should be examined. Individuals that endure long term exposure to sunlight may be at risk due to the presence of ultraviolet light. Long term exposure to lead and radiation can also lead to cataracts. In some cases, these could be an occupational hazard which means that following safety practices is extremely important.
