Manganese is an important trace element that is vital for the health of our eyes. It is an essential component of enzymes and antioxidants that provide protection against oxidative stress. Oxidative stress occurs when harmful free radicals are produced in the body and attack the cells. This stress can lead to damage to cells and tissues, including the eyes. Manganese helps the body fight these free radicals and minimize their damage. In addition, manganese plays a role in the production of collagen, an important structural component of eye tissue. Collagen is responsible for the strength and elasticity of tissues, including the lens and retina. A manganese deficiency can lead to a deterioration in eye health. Dry eyes, inflammation of the conjunctiva and retinal problems are common problems associated with a lack of manganese. An adequate intake of manganese can improve eye function and reduce the risk of eye diseases. There are various ways to meet manganese requirements. A varied diet with manganese-rich foods such as whole grains, nuts, legumes, green leafy vegetables and dried fruits can help to meet manganese requirements. A balanced diet and a healthy lifestyle overall is the best way to promote eye health.
