A healthy and varied diet is generally important for the proper functioning of the body, as well as for the health of the eyes.
It is good to include foods rich in omega-3 fatty acids, lutein, zinc and vitamins C and E in your diet. This means that your diet should contain plenty of green leafy vegetables, citrus fruits and nuts.
Also, provide the body with sufficient hydration, as the quality of tears depends on this. It is recommended to drink two liters of water a day. In the summer months, this need is even greater, so always carry a bottle of water with you.
