There are some elements that are directly related to eye function, others that are linked to a healthy lifestyle. Failure to comply with the latter leads to the intake of drugs that alter the homeostatic equilibrium of the eye and therefore affect the lacrimal surface and the entire visual apparatus. Vitamin A, B, C, D and E, along with antioxidants such as coenzyme Q10, lutein, zeaxanthin, melatonin, Omega-3 and beta-carotenes keep tears healthy. Any hormonal alteration or drug intake or incorrect diet can modify the tear film and therefore lead to annoying dry eye up to alteration to the cornea.
