Retina - Highest Oxygen Consuming Tissue of the Body

Did you know that the retina is the highest oxygen-consuming tissue of the body?

According to the January 17, 2003 issue of the Journal of Biological Chemistry "... the relative oxygen consumption of the mammalian retina is higher than that of the brain and other tissues. It is assumed that, on a per gram basis, the retina is one of the highest oxygen demanding tissues of the human body."


Because the many visual functions of the retina require large amounts of oxygen there is also a high degree of oxidation which means that the retina is very vulnerable to free radical damage.

Prevent and Repair Retinal Degeneration




And free radicals cause damage to our eyes resulting in eye conditions like cataracts and macular degeneration. Foods high in antioxidants fight to prevent and repair the damage caused by these rogue electrons. 

Perhaps like me you need a reminder on how important it is to include antioxidant rich foods in your diet. From fruits and vegetables to green tea and raw cacao, get a list of foods that are most able to fight oxidative damage going on in your eyes:

Children Warned Off 3D Viewing

Optometry Australia has warned that 3D movies may have dangerous effects on the vision of young children and people with impaired vision.

Luke Arundel, Optometry Australia's senior resident optometrist, said glasses required to screen movies in 3D can cause fatigue or irritation. 
3D glasses work by filtering images so the left eye sees one image and the right eye sees a slightly different one. The brain then fuses them together to perceive a 3D image. 

However for this to happen, the viewer's eyes must work well together. Where vision is underdeveloped or damaged, 3D glasses may cause fatigue or irritation.
