The burning sensation in your eyes when you cry is commonly caused by the unique composition of emotional tears, which include extra proteins, hormones, and stress-related chemicals. These tears have a higher salt content and different makeup than basal tears, leading to irritation on the sensitive eye surface and a burning feeling. Additionally, underlying issues such as dry eye, blepharitis (eyelid inflammation), allergies, or environmental irritants like smoke, pollution, or sweat can worsen this burning sensation during crying. Dry eye can cause the eyes to produce tears that lack the proper oily layer, leading to irritation and burning. Reflex tears, produced to wash away irritants, also contain more antibodies, enzymes, and salt, contributing to the stinging sensation temporarily. If the burning is severe or persistent, it may be due to these underlying conditions and should be checked by an eye doctor for proper diagnosis and treatment.
