Each tiny area of cloudiness blocks a bit of light getting through to the retina. The severity of the cataract depends on the number of areas of cloudiness that develop in the affected lens. […] Factors that may increase the risk of developing cataracts include: Having a poor diet. Smoking. Diabetes. Steroid medicines. Having a family history of cataracts. Ultraviolet radiation from sunlight and other sources. High blood pressure (hypertension). Obesity. Statin medicines used to reduce cholesterol. Previous eye injury or inflammation. Previous eye surgery. Significant alcohol consumption. Use of hormone replacement therapy (HRT) for a prolonged period (more than ten years). Severe short-sightedness (high myopia).

  Cataracts develop due to the denaturation of the proteins in the lens. As we age, proteins degenerate, resulting in a cluster of dense protein clumps forming cataracts, with the lenses becoming opaque. Cataracts are more prevalent in those aged over 60. In addition, cataracts can also result from tissue injuries around the lens or in the eye, an infectious eye disease, and congenital rubella infection in the womb. […] Cataracts can affect both men and women and can affect one or both eyes, but they neither hurt nor irritate the eyes. […] Cataracts are more prevalent in those aged over 60.

  Cataracts refer to the cloudy occlusion of the eyes natural lens. Although cataracts occur most often in the elderly, anyone, at any age, can develop a cataract. A cataract forms when the lens becomes thicker, more rigid and exceedingly opaque. Incoming light is no longer able to focus onto the retina properly, resulting in loss of vision. A secondary cataract may form after surgery or experiencing other eye health problems. This type of cataract is commonly found in those with diabetes, eye injury, glaucoma or other metabolic disorders. A traumatic cataract develops after traumatic injury to the eye. When someone is born with a cataract, the cataract is referred to as a congenital cataract. Exposure to radiation may also induce the formation of a cataract, known as a radiation cataract. Certain lifestyle choices or health problems may increase the chance of developing a cataract: Diabetes, kidney disease, endocrine disorders or another metabolic condition

• #158 The Causation and Pathophysiology of Cataracts

  https://www.longdom.org/articles/the-causation-and-pathophysiology-of-cataracts-98212.html

  A cataract is a hazy spot in the eye’s lens that causes visual loss. Cataracts usually grow gradually and might damage one or both eyes. […] Cataracts are most usually caused by ageing, although they can also be caused by trauma or radiation exposure, be present from birth, or develop after eye surgery for other reasons. […] Diabetes, long-term use of corticosteroid medicine, tobacco usage, prolonged sun exposure, and alcohol are all risk factors. […] The underlying mechanism involves the buildup of clumps of protein or yellowbrown pigment in the lens, which limits light transmission to the retina at the rear of the eye. […] The most common cause of cataracts is aging. Lens proteins denature and degrade over time, which is increased by disorders such as diabetes and hypertension. […] Oxidative stress is a major pathogenic factor in cataract development. Senile cataracts are related with a reduction in the lens’s antioxidant capability. An increase in oxidative stress or a decrease in the lens’s capacity to remove reactive oxygen species can cause the lens to become more opaque. […] Cataracts can develop as a result of several types of radiation exposure. X-rays, one form of ionizing radiation, may damage the DNA of lens cells. Ultraviolet light, notably UVB, is also believed to produce cataracts.
