2021, Journal of Trace Elements in Medicine and BiologyCitation Excerpt :This is not surprising as human tears have a different physiological function, as discussed above. Moreover, they are produced by the lacrimal glands located above the eyes and the amount of water responds to the degree of irritation [39]. In addition to water, crying tears contain various electrolytes (Na+, K+, Cl−, HCO3−), Ca/Mg, fatty oils, antibodies, lysozymes (antibacterial enzymes) and many different proteins [40].

2019, Trends in BiotechnologyCitation Excerpt :Notably, daily wear of contact lenses is considered ‘safe’ in people with diabetes as they do not cause significant differences in terms of bulbar redness, corneal staining, corneal thickness, and corneal sensitivity and do not compromise corneal integrity. The second reason is that the glucose monitoring can be carried out directly through tear secretion and blinking, while sample collection with the aid of external stimuli could potentially alter the tear fluid composition [15]. The third reason is contact lenses are easy to wear, use, and remove.

Homo sapiens are the only animals that, in its ethological behavior, has at present been proven to have developed lachrymal psycho-emotional hypersecretion in some specific emotional states of mind.
