Supporting eye health is an important step to improving an individual’s quality of life. Impaired vision due to nutritional deficiencies and sunlight exposure can negatively impact our daily activities and independence.

Taking action to maintain healthy eyes may help reduce the incidence of premature vision loss due to strain and disease. Eye health can be supported with the use of eye exercises, proper nutrition, and appropriate natural health products, such as lutein.

Eye Health: Diet and Lifestyle

Important dietary and lifestyle considerations for eye health support include:

  • Eating for good vision by incorporating green, leafy vegetables, such as spinach, kale, and collards, salmon, tuna and other oily fish, eggs, nuts, oranges and other citrus fruits [1].
  • Smoking cessation as smoking increases your risk for cataracts and macular degeneration, the leading causes of visual impairment and adult blindness [1].
  • Wearing sunglasses to protect your eyes from UV rays [2].
  • Taking regular breaks from using a computer and other electronic devices, which tend to cause eyestrain and blurry vision.
  • Consider natural health products such as lutein, zeaxanthin, and omega-3 fatty acids [3] [4] [5].

Benefits of Lutein

Lutein, and its stereoisomer, zeaxanthin, are carotenoid pigments found naturally in the eyes, concentrated particularly in the macula and retina. Carotenoids are also known for their role in providing bright colours in fruits and vegetables.

Lutein filters the high-energy, blue wavelengths of light from the visible-light spectrum by as much as 90%. Blue light, in both indoor lighting and sunlight, is believed to induce oxidative stress and possible free-radical damage in human organs exposed to light, such as the eyes and skin. Carotenoids, such as lutein and zeaxanthin, are important antioxidants through their ability to defend against this oxidative stress.

Lutein products provided by Webber Naturals are available in 6 mg, 10 mg, 20 mg, and 40 mg potencies, to provide antioxidant protection for the maintenance of eye health, as well as help improve macular pigment optical density and support eye conditions associated with sunlight damage such as cataracts and age-related macular degeneration. Speak to your health care practitioner to determine if lutein would be appropriate for you.
