Cataract Risk Factors

Cataracts are a prevalent eye ailment affecting millions of individuals worldwide. Cataracts may develop at any age, although they are more frequent in adults over 60. This article will go through the reasons and risk factors for cataracts, such as age, eye trauma, and certain medical diseases.



The most prevalent cause of cataracts is aging. As we age, the natural proteins in our eyes’ lenses might break down and clump together, resulting in a cataract. The lens also loses flexibility, making it more difficult for the eye to concentrate on things at various distances.

Several variables, in addition to age-related changes, may contribute to the development of cataracts. Here are some examples:


Injury to the Eye

Cataracts may occur as a result of eye trauma. This may involve both injuries to the eye and damage to the surrounding region. For example, being struck in the eye with a ball or other item may induce lens damage and the formation of a cataract.


UV Radiation Exposed

UV light exposure may potentially contribute to the development of cataracts. UV radiation from the sun may damage the proteins in the lens, causing a cataract to develop. This is why it is critical to wear UV-blocking sunglasses while you are outdoors.



Another risk factor for cataracts is smoking. Individuals who smoke are more prone than nonsmokers to get cataracts. This might be because smoking creates oxidative stress, which can damage the proteins in the lens and cause cataracts to develop.


Certain Medical Conditions

Some medical disorders might also raise your chances of getting cataracts. Here are some examples:



Diabetes may produce ocular abnormalities that raise the likelihood of acquiring cataracts. High blood sugar levels may damage the proteins in the lens, causing a cataract to occur. Diabetes also increases the chance of developing other visual disorders, such as diabetic retinopathy, which may raise the risk of cataracts.


Blood Pressure Is Excessive

High blood pressure increases your chances of acquiring cataracts. This might be because high blood pressure damages the blood vessels in the eye, causing changes in the lens.



Another risk factor for cataracts is obesity. Overweight or obese people are more prone to acquire cataracts than those who are not. This might be because obesity can create metabolic changes that impact the lens.



Cataract formation may also be influenced by genetics. Some individuals are prone to acquiring cataracts genetically, while others may have a family history of the ailment. If cataracts run in your family, it is important to get frequent eye examinations to check your eyesight and catch any changes early on.


Cataracts are a common eye ailment that may impair your eyesight and quality of life significantly. Although aging is the most prevalent cause of cataracts, other variables might raise your chances of having cataracts. If you have a history of any of the risk factors listed above we at Cohen eye institute encourage you to get your eyes checked so that we work together to monitor and treat your cataracts should it be needed.
