Yes, when a blind person cries, tears still form, just like in individuals with sight. Crying is a natural response to strong emotions such as sadness, joy, or frustration, and it serves as a way for the body to release and express those emotions.
Tears are produced by the lacrimal glands located above each eye. These glands continually produce tears to keep the eyes moist and lubricated. When a person experiences strong emotions, the nervous system can stimulate the production of additional tears, leading to crying.
The tears then flow down the eyes and usually drain through the tear ducts, which are small channels that lead to the nasal cavity. This is why you might feel a runny nose or get a lump in your throat when you cry.
In summary, blindness does not affect the body's ability to produce tears, and blind individuals can cry just like anyone else. The experience of crying and the emotional release it provides are not dependent on one's ability to see.
