Eye Factors natural ingredients include:

• Vitamin A
  We all know that vitamin A is important for eye health. Retinal, a form of vitamin A, is needed to for night vision. Indeed, the retina uses four different types of vitamin A-containing photopigments (1 for night vision and 3 for day vision).
  
  
• Zeaxanthin and Lutein
  Zeaxanthin and lutein are major components of macular pigment, which is a pigment found in the macula - a small yellow spot located in the central part of the retina.
  
  Macular pigment functions to absorb short-wave light to protect the eye. It is also responsible for acuity vision, which allows you to read, sew, and perform other activities which require acute vision.
  
  
• Cryptoxanthin
  Cryptoxanthin is an oxygen derivative of carotenes, a member of the yellow carotenoid family. Carotenes are plant pigments that give plants their colors.
  
  Carotenoids are important for eye health by lowering the risk of developing cataracts and possibly macular degeneration.
  
  
• Carotenes
  Found in leafy, green plants, carotenes have the highest conversion rate to vitamin A.
  
  
• Lycopene
  Lycopene is found in red fruits and vegetables, such as watermelon, red grapefruit, and tomato. It is a form of carotene with the highest oxygen quenching power, which helps prevent free-radical damage to the eyes.
  
  
• N-Acetyl Cysteine (NAC)
  This amino acid is closely related to cysteine, and can stimulate the body's production of antioxidants.
  
  
• Bilberry
  Bilberry fruit is composed of active flavonoid complexes called anthocyanosides. These natural compounds are powerful antioxidants, and support the normal formation of connective tissues as well as strengthen capillaries for optimal eye health.
  
  
• L-Glutathione
  This amino acid helps protect the lens of the eye by protecting the tissue surrounding it.
  
  
• Copper
  This element is essential for the formation of collagen, and is a fundamental component of certain proteins in bones, skin, and connective tissues.
  
  
• Zinc
  Eyes contain the highest concentration of zinc in the body - this essential element enhances the conversion of beta-carotene into vitamin A.
