In a study published in the April 2010 issue of the American Journal of Clinical Nutrition researchers wanted to determine the role of DHA supplementation on the visual acuity of formula-fed infants. DHA, along with EPA, are the two omega-3 fatty acids in fish oils. Healthy, term, formula-fed infants were randomly assigned to be fed an infant formula containing equivalent nutrient amounts, except for long-chain polyunsaturated fatty acids. Infants fed the control formula had significantly poorer visual acuity at 12 mo of age than did infants who received a DHA-supplemented formula. http://www.raysahelian.com/dha.html
Comments: Years ago, when I was in the process of writing my book Mind Boosters, I experimented with taking fish oil softgels in different amounts. I noticed that when taking 5 or more in the morning, my vision would become sharper by afternoon. The retina of the eye requires DHA for optimal visual acuity. I then started experimenting with different herbs and nutrients to see if others had an influence on vision. Over the years I found several that had a positive role to play in eye health which led me to formulate Eyesight Rx, a dietary supplement that melts under the tongue for quick and efficient absorption. Most users find improvement within a few days: better day and night vision, and better reading and distance acuity. See http://www.raysahelian.com/eyesight.html
