Insights on Active Oxygen and Eye Diseases: The Role of Tea in Prevention

As we age, insults related to active oxygen increase, leading to various diseases. The crystalline lens and retina are the two eye organs most affected by active oxygen. Senile cataract, where the crystalline lens becomes cloudy due to the oxidation of soluble proteins by active oxygen, is a prevalent disease among the elderly. Similarly, senile Ouhanhenseisho of the retina is the leading cause of blindness among senior people in the United States.

Understanding Senile Ouhanhenseisho of Retina

Senile Ouhanhenseisho of retina is a disease that causes failure of eyesight by disrupting the ability of eye cells to distinguish characters and colors in Ouhanbu of the retina. The disease’s structure, causes, prevention, and remedies are not yet fully known, but the recognition of Ribofusuchin material called Doruze appears to be related to it. Ripofusuchin is known to increase with aging in many organs such as the brain and heart. The generation system of Ripofusuchin is unknown, but it is believed to be generated when aldehyde and lipid dioxide react with protein.

Preventing Oxidative Influence by Active Oxygen

To prevent the oxidative influence of active oxygen, various anti-oxidative materials in the human body work. Water-soluble anti-oxidative material helps prevent the oxidation of crystalline lens, while lipid-soluble anti-oxidative material works to prevent the oxidation of the retina. Tea leaves contain many anti-oxidative materials such as water-soluble vitamin C, lipid-soluble vitamin E and carotene, water, and lipid-soluble catechins, including epigallocatechin gallate, which is unique to tea.

The Role of Tea in Preventing Eye Diseases

Tea catechins significantly reduce the generation of water-soluble Ripofusuchin, a fluorescent substance generated by oxidation of the retina of a pig, and prevent the generation of aldehyde from dioxidized lipid. Drinking tea containing various anti-oxidative materials, such as catechins, can be proven to be effective against eye diseases with further research. Thus, tea, which contains caffeine, theanene, and catechins, is expected to be effective in preventing dimentia.
