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.

Binge Eating Disorder

Binge eating disorder is an eating disorder characterized by repeated episodes of eating unusually large amounts of food while feeling unable to control the eating. Episodes may involve eating rapidly, eating when not physically hungry, continuing until uncomfortably full, or eating alone because of embarrassment. Unlike bulimia nervosa, binge eating is not routinely followed by behaviors such as self-induced vomiting or misuse of laxatives to compensate for eating. The disorder is treatable and can affect physical and emotional health.

Diagnosis

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.

Binge Eating Disorder

Diagnosis is based on the pattern and frequency of binge-eating episodes, the sense of loss of control, associated behaviors and emotions, and the absence of regular compensatory behaviors characteristic of bulimia. A healthcare professional will ask about eating habits and symptoms and may perform a physical examination. Blood tests or other medical assessments may be used to identify health effects or related conditions. Psychological evaluation can help identify emotional factors and coexisting mental health problems.

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.

Binge Eating Disorder

There is no guaranteed way to prevent binge eating disorder, but regular and balanced eating patterns may help avoid cycles of severe restriction followed by overeating. Developing healthy ways to manage stress and emotional distress can also be useful. Avoiding extreme dieting and seeking help for persistent concerns about eating, body image, or loss of control may allow earlier intervention. Treatment commonly includes psychological and nutrition counseling, which can help reduce binge episodes and address factors that maintain the disorder.

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.

Binge Eating Disorder

Risk factors include a family history of eating disorders, emotional distress, depression or anxiety, and patterns of restrictive or irregular eating. Experiences that contribute to negative emotions or difficulty managing stress may increase vulnerability. Binge eating can occur in people of different ages and backgrounds and may occur with other mental health or eating-related conditions. Body weight alone does not establish whether a person has binge eating disorder, so assessment should focus on eating behavior and loss of control.
