Diets rich in antioxidants, such as vitamins C and E, carotenoids, and omega-3 fatty acids, are believed to lower the risk of cataracts.
A cataract is a clouding of the eye’s natural lens, which lies behind the iris and the pupil. The lens is normally clear and allows light to pass through to the retina, where the light is processed into visual information. When a cataract forms, it causes the lens to become cloudy, scattering light and reducing the clarity of vision. If left untreated, it can result in blindness.
An Overview of Cataracts
Common symptoms of cataracts include blurred vision, difficulty seeing at night, sensitivity to light and glare, seeing “halos” around lights, fading, or yellowing of colours, and frequent changes in eyeglass or contact lens prescriptions.
Cataracts are typically diagnosed through a comprehensive eye examination, which may include a visual acuity test, a dilated eye exam, and tonometry (measuring the pressure inside the eye).
The primary cause of cataracts is aging. Other factors include genetic predisposition, diabetes, smoking, excessive alcohol consumption, prolonged exposure to ultraviolet sunlight, certain medications (like corticosteroids), and previous eye injuries or surgeries.
In the initial stages, improved lighting and eyeglasses can help manage the symptoms. When cataracts interfere with daily activities, cataract surgery is the most effective treatment. This surgery involves removing the cloudy lens and replacing it with an artificial intraocular lens.
Other symptoms of skin cancer may include sores that do not heal, bleeding or oozing lesions, itching, tenderness, or pain. In advanced stages, skin cancer can spread to nearby lymph nodes or other organs, causing additional symptoms such as swollen lymph nodes, difficulty breathing, or abdominal pain.
Early detection of skin cancer is crucial for successful treatment. Regular self-examinations of the skin, paying attention to any changes in moles or the appearance of new lesions, can help in detecting skin cancer at its earliest stages. Any suspicious lesions should be evaluated promptly by a dermatologist. Additionally, practicing sun safety, such as wearing sunscreen, protective clothing, and staying in the shade, can help reduce the risk of developing skin cancer.
