What is a Cataract? A cataract is the clouding or whitening of the natural lens of the eye. The lens is normally clear, just like a clean window, allowing light to pass through so you can see clearly. When a cataract develops, the lens becomes cloudy, making vision blurry, dull, or foggy. A Simple Example Imagine looking through: A clean glass window – you see everything clearly. A dusty or frosted glass window – everything looks blurred. A cataract is like looking through a dirty window. --- How the Eye Normally Works Think of the eye like a camera. The parts include: Cornea – the front transparent covering. Pupil – the black opening that lets light in. Lens – focuses light. Retina – receives the image. Optic nerve – sends the image to the brain. When the lens becomes cloudy, light cannot pass through properly, causing poor vision. --- What Causes Cataracts? A cataract develops when proteins in the lens become damaged and clump together.(Very important to take note of) Major Causes 1. Ageing (Most Common) As people grow older, the lens naturally becomes less clear. Usually after age 50. --- 2. Diabetes High blood sugar damages the lens over time. People with poorly controlled diabetes develop cataracts earlier. --- 3. Too Much Sunlight Years of exposure to ultraviolet (UV) rays can damage the lens. Example: Farmers Fishermen Construction workers Drivers --- 4. Smoking Smoking releases toxins that increase oxidative damage to the lens. --- 5. Alcohol Abuse Heavy drinking increases oxidative stress. --- 6. Eye Injury A blow, cut, or accident can cause cataracts. --- 7. Steroid Medicines Long-term use of steroid tablets, injections, or eye drops increases the risk. --- 8. Radiation Exposure to radiation can damage the lens. --- 9. Family History Some people inherit genes that increase the risk. --- 10. Poor Nutrition A lack of antioxidant nutrients can increase the chance of cataracts. --- 11. Obesity Obesity is linked with inflammation and diabetes. --- 12. High Blood Pressure Long-term hypertension affects the blood vessels supplying the eye. --- 13. Congenital Cataracts Some babies are born with cataracts due to infections during pregnancy or genetic conditions. --- Types of Cataracts 1. Age-related Cataract The most common type. --- 2. Congenital Cataract Present at birth. --- 3. Traumatic Cataract Caused by eye injury. --- 4. Secondary Cataract Occurs because of diseases such as diabetes or long-term steroid use. --- 5. Radiation Cataract Develops after exposure to radiation. --- Types Based on Location Nuclear cataract – forms in the center of the lens. Cortical cataract – starts at the edges. Posterior subcapsular cataract – forms at the back of the lens and often affects near vision and causes glare. --- Signs and Symptoms People may notice: Blurred vision Cloudy vision Foggy vision Dim vision Double vision in one eye Poor night vision Glare from headlights Halos around lights Frequent changes in glasses prescription Faded colours Difficulty reading Needing brighter light Difficulty recognizing faces Frequent stumbling or falls --- Early Warning Signs Difficulty reading small print Trouble driving at night Increased sensitivity to sunlight Frequent eye strain Seeing halos around lights --- Risk Factors Age over 50 Diabetes Smoking Alcohol Obesity Steroid use High blood pressure Poor nutrition Family history Previous eye surgery Long-term UV exposure --- Possible Complications If untreated, cataracts can lead to: Severe vision loss Blindness (usually reversible with surgery and some medicines Falls and injuries Reduced independence Depression due to vision impairment Increased risk of accidents --- Diagnosis An eye care professional may perform: Visual acuity test (eye chart) Slit-lamp examination Retinal examination after dilating the pupils Measurement of eye pressure to check for glaucoma . Treatment Naturopathic Approach Diet Eat plenty of: Dark green leafy vegetables (kontomire, spinach) Carrots Tomatoes Oranges Lemons Mangoes Pawpaw Avocado Garden eggs Bell peppers Cabbage Broccoli Pumpkin Sweet potatoes Foods rich in: Vitamins A, C, and E Zinc Selenium Omega-3 fatty acids Lutein and zeaxanthin (found in leafy greens and egg yolks) --- Foods to Reduce Excess sugar Soft drinks Highly processed foods Deep-fried foods Trans fats Excess alcohol Smoking --- Hydration Drink enough clean water daily to support general health. --- Weight Management Maintain a healthy weight and exercise regularly to reduce the risk of diabetes and high blood pressure. --- Eye Protection Wear UV-blocking sunglasses outdoors.
