Overview
Cataract
A cataract is a clouding of the normally clear lens inside the eye. As the lens becomes cloudy, less light reaches the retina and vision may become blurred, dim, or less sharp. Cataracts usually develop gradually and are most common with increasing age, although they can also occur after eye injury, surgery, certain diseases, or prolonged exposure to factors that damage the lens. Cataracts may affect one or both eyes but do not spread from one eye to the other.
Type 2 Diabetes Mellitus
Type 2 diabetes mellitus is a chronic metabolic disorder in which the body becomes resistant to insulin and, over time, may not produce enough insulin to maintain normal blood glucose levels. Persistent high blood sugar can damage blood vessels, nerves, kidneys, eyes, and other organs. The condition can often be managed through lifestyle measures, medicines, and regular monitoring.

Cataract
Cataracts are diagnosed through an eye examination and assessment of vision. An eye care professional may test visual acuity and examine the lens and other structures of the eye using a slit lamp or other instruments. The pupils may be dilated so that the back of the eye can be examined and other causes of vision loss can be assessed. Additional tests may be used when another eye condition is suspected or when surgery is being planned.
Type 2 Diabetes Mellitus
Type 2 diabetes is diagnosed using blood glucose testing. Common diagnostic methods include fasting plasma glucose, glycated hemoglobin, or an oral glucose tolerance test, with confirmation generally required when appropriate. A random glucose measurement may establish the diagnosis in a person with characteristic symptoms and markedly elevated glucose. Additional tests may be used to evaluate complications and cardiovascular or kidney risk.
Prevention
Cataract
Not all cataracts can be prevented, especially those related to aging. Measures that may help reduce risk include protecting the eyes from ultraviolet light with appropriate sunglasses and a wide-brimmed hat, avoiding smoking, protecting the eyes from injury, and controlling medical conditions such as diabetes. A healthy diet containing fruits, vegetables, leafy greens, nuts, and whole grains may support overall eye health. Regular eye examinations can help detect cataracts and other causes of vision changes.
Type 2 Diabetes Mellitus
The risk of type 2 diabetes can often be reduced through regular physical activity, maintaining a healthy body weight, eating a balanced diet rich in minimally processed foods, avoiding tobacco, and limiting excessive alcohol intake. People at increased risk may benefit from regular screening and structured lifestyle programs. Early identification of abnormal blood glucose can allow preventive measures before diabetes becomes established.
Risk Factors
Cataract
Older age is the most important risk factor for cataracts. Other factors include diabetes, a family history of cataracts, previous eye injury or eye surgery, long-term use of corticosteroids or certain other medicines, smoking, radiation exposure, and prolonged ultraviolet light exposure. Some inflammatory eye diseases and other medical conditions can also increase risk. Risk generally increases as the lens is exposed to these factors over time.
Type 2 Diabetes Mellitus
Risk factors for type 2 diabetes include overweight or obesity, physical inactivity, increasing age, family history, previous gestational diabetes, high blood pressure, abnormal cholesterol levels, and certain patterns of abdominal fat distribution. Risk also varies among populations because of genetic, social, and environmental factors. Having a risk factor does not mean diabetes will definitely develop.
