Vision Tonic is a Shen original formulation that combines traditonal herbs from east and west and includes tradional herbs based on their scientific pharmacological / chemical content as it relates to healthy eyes and eyesight. The result is a tincture that combines herbs traditionally know to improve eyesight with herbs that contain substances that science has shown to have a benefitial effect on eyesight and on the eyes themselves. These chemical components include Beta-Carotene, Lutein, Zeaxanthin and other caretonoids. The difference is they are in their natural state and are not separeated, isolated, concentrated or manipulated in any way. This strategy allows us to take advantage of modern scientific reaserch in synergy with the use of ancient traditional herbology. 
 
In addition, Vision tonic adds herbs that benefit micro-circulation and herbs that are used traditionally for eye conditions such as: glaucoma, eye relaxation, for eliminating floaters, that have shown beneficial results with age related macular degeneration, and skin growth on conjuctiva (Pinguecula /Pterygium). 
 
How to use: Do not use as eyedrops. Apply 10 to 15 drops under the tongue, 2 or 3 time per day. If the taste is too strong, you can also mix the drops with a small amount of water, but the effect and the path of absorption will be very different. Caution: Not for use during pregnancy. Keep out of reach of children.
