Presentation Transcript

  1. How the human eye sees • Lens of the eye bends/refracts light • Image is formed when light reaches the retina Myopia

  2. Myopia—Refractive error of the eye that makes distant objects appear blurred • Distorted lens • Elongation of the optic axis • Images cannot form at retina • Light is focused in front of retina Myopia

  3. Causes of Myopia • Genetics • Research findings Children with both parents myopic: • More than 6 times as likely to become myopic as children with only one or no myopic parents • 30% – 40% have myopia

  4. Causes of Myopia • Genetics • Research findings • Children with 1 myopic parent:Only 20% – 25% have myopia • Children without myopic parents:Only 10% have myopia

  5. Causes of Myopia • Inherited myopia progresses regardless of environmental factors

  6. Myopia • Spend time outdoors From a study of over 4,000 students aged 6 or 12 in Australia: Myopia is associated with high levels of near work and low levels of outdoor activity. • Intense outdoor light • Constricts pupils • Stimulates the retina to release dopamine • Inhibits elongation of optic axis

  7. Preventing Myopia Diet A study on 851 Chinese schoolchildren by the Singapore Eye Research Institute found that: Higher intakes of saturated fat and cholesterol were associated with myopia.

  8. Cataracts • Eye lens—Water and protein • Protein • Keeps the lens clear • Helps to capture clear images at the retina • Clouding of the lens—clumping of protein • Discoloration of the lens—yellow or brown tint

  9. Cataracts • May occur in one or both eyes • Will not spread from one eye to the other • Main cause of impaired vision • Higher incidence in women

  10. Risk Factors of Cataracts • Old age • A family history of cataracts • Long-term steroid usage • Smoking • Myopia • Eye injuries • Overexposure to sunlight • Diabetes, hypertension and obesity

  11. Diet and Cataracts • Meat and dairy productsIncrease the risk of cataracts Cataracts

  12. Diet and Cataracts • Low intake of plant foods • NutrientsResearchers found that: • Cataract patients have low levels of Vitamin C. • Cataract risk was reduced for people with higher intakes of vitamin D and carotenoids.

  13. Diabetes and Retinal Diseases • Diabetic retinopathy a complication of diabetes

  14. Diabetes and Retinal Diseases • Retinopathy generally affects patients who have had diabetes for at least 10 years. Retinopathy occurs in: • Around 10% of diabetics after 5 – 9 years • Around 50% of diabetics after 15 years • Around 80% – 90% of diabetics after 25 years • After 30 years, 25% of diabetics develop proliferative diabetic retinopathy, and 2% – 7% eventually turn blind.

  15. Diabetes and Retinal Diseases • Grape seed—oligomeric proanthocyanidins (OPCs) • Help to slow the progression of diabetic retinopathy • Strengthen blood vessels in the eyes and improve blood circulation in the eyes • A controlled trial revealed: 60% of diabetics taking 150 mg per day of OPCs from grape seed extract had no progression of retinopathy compared to 47% of those taking a placebo.

  16. Diabetes and Retinal Diseases • Chinese Wolfberry—contains high levels of polysaccharides, polyphenols, zeaxanthin and lutein • University research in the U.S. showed that Chinese wolfberries have high antioxidant activity and can lower oxidative stress that the eye undergoes as a result of type 2 diabetes.

  17. Glaucoma • Disease resulting in optic nerve damage • Pressure within the eye increases • High chance of permanently impairing vision, even causing blindness

  18. Glaucoma • Caffeine intake increases eye pressure in glaucoma patients Vitamin deficiency does not lead to glaucoma • Hereditary • A family history of glaucoma makes one 2 – 4 times as likely to acquire glaucoma • Caused by mutations in various genes

  19. Secondary Glaucoma • Causes • Diabetic retinopathy—Restricted blood flow to the eyes • Long-term use of steroids • Glaucoma patients are 29% more likely to suffer from hypertension than the average person

  20. Secondary Glaucoma • Preventive measures • Prevention against obesity and diabetes • Maintain retinal health • Healthy diet

  21. Computer Vision Syndrome • Short-term effects • Headache • Blurred vision • Neck pain • Red eyes • Fatigue • Eye strain • Dry eyes • Stinging eyes • Double vision

  22. Dry Eyes • Main symptom of Sjögren’s Syndrome • Sjögren’s Syndrome • An autoimmune disorder • Occurs more frequently in postmenopausal women

  23. Dry Eyes • For relief • Omega-3 • Artificial tears • Humidifier • Sleep with eyes closed • Reduce use of anti-allergy drugs • Blink more often

  24. Diet and Cataracts • Fats • High intake of omega-6 fatty acids may increase the risk of age-related cataracts • High intakes of vegetable oils and trans fats—associated with higher risk of early nuclear cataracts • Intake of mayonnaise and creamy salad dressings—linked to cataracts in women

  25. Cassia Seed • Very beneficial to the liver and eyesight • Protects the liver by boosting the activities of antioxidant enzymes

  26. Cassia Seed • Helps to scavenge free radicals • Cassia seeds have long been used in TCM as a tonic for the liver, eyes and kidneys • Eye conditions such as dim vision and night blindness • Relieves red, sore and swollen eyes due to liver inflammation

  27. Chia Seed • Important source of alpha-linolenic acid (ALA) • Has powerful anti-inflammatory effects

  28. Chia Seed • Helps to prevent eye conditions linked to oxidative stress and inflammation • Dry eye syndrome (DES) • Age-related macular degeneration (AMD) • Cataracts • Diabetic retinopathy

  29. Blueberry • High concentration of antioxidants and phytochemicals Anthocyanins • Powerful antioxidants • Defends against free radical damage • Supports the retina Experimental studies showed that anthocyanins significantly reduced retinal damage compared to placebo

  30. Blueberry • Effectively neutralizes free radicals and defends the retina

  31. Carrot • Supports night vision • Aids dry eyes • Reduces glaucoma risk • Helps the retina function properly

  32. Carrot • Contains carotenoids, which are powerful antioxidants • A U.S. study showed that the risk of glaucoma was lowered by 64% in women who ate more than 2 servings of carrots a week compared with those who ate less than 1 serving a week.

  33. Chinese Wolfberry • Long history of use in TCM to nourish the liver and kidneys, and support vision • High level of zeaxanthin • A carotenoid with antioxidant effects • Maintains macular pigment optical density

  34. Chinese Wolfberry • Contains polysaccharides, polyphenols and lutein • Improves vision • Supports the eyes against harmful blue light • Defends against age-related macular degeneration (AMD) • Defends against diabetic retinopathy

  35. Grape Seed

  36. Broccoli • Rich in lutein and zeaxanthin • Studies have shown that high intakes of lutein and zeaxanthin (particularly from broccoli) significantly reduce risk of • Cataract—up to 20%

  37. Broccoli • Rich in lutein and zeaxanthin • USA一In a study of 36,644 people,those with the highest intakes of lutein plus zeaxanthin had 19% lower risk of cataract compared to those with the lowest intakes.

  38. Brussels Sprouts • Zeaxanthin—Protects against retinal damage, cataracts and macular degeneration • Selectively absorbed into the retinal macula lutea in the eyes • Supports the eyes • Helps fight cataracts and macular degeneration • Antioxidant and UV light-filtering functions • Defends against retinal damage • Rich in antioxidants • Rich in alpha-linolenic acid (ALA)

  39. Yellow Pepper • A type of bell pepper / sweet pepper • Wide range of colors: Red, orange, yellow, green, purple, brown, etc. • Color depends on the time of harvest, growing conditions, and cultivation processes

  40. Yellow Pepper • Excellent source of antioxidants • More than 30 different carotenoids • Highest level of carotenoids compared to green and red peppers • Rich in beta-carotene • Helps improve vision • Combats oxidative stress in the eyes caused by free radicals

  41. Yellow Pepper • Contains violaxanthin and lutein • Prevents macular degeneration and cataracts
