As an expert in the field of human physiology, I can provide a comprehensive answer to the question of whether blind people cry. Crying is a complex emotional and physiological response that involves the production of tears, which are a natural secretion from the lacrimal glands in the eyes. The act of crying can be triggered by a range of emotions, including sadness, joy, frustration, and even physical pain.

### The Lacrimal Glands and Tear Production

The lachrymal glands are responsible for the production of tears, which serve several purposes. They help to lubricate the eyes, wash away irritants, and are also a part of the emotional response to certain stimuli. There are three types of tears produced by the lacrimal glands:


1. Basal tears: These are the tears that are constantly produced to keep the eyes moist and healthy.

2. Reflex tears: These are produced in response to irritants, such as when you get dust in your eyes.

3. Emotional tears: These are the tears associated with strong emotions, which is the type most people think of when they consider crying.

### The Relationship Between Blindness and Tear Production

Blindness is a condition where an individual has a significant impairment in their vision, which can range from a mild difficulty in seeing to complete inability to see anything. However, the production of tears is not directly linked to the ability to see. The lacrimal glands function independently of the retina and optic nerve, which are the components of the visual system. Therefore, a person who is blind can still produce tears.

### Emotional Crying in Blind Individuals

While the physical act of crying is possible for blind individuals, there might be some differences in the emotional experience of crying. For sighted people, visual cues can contribute to the emotional response that leads to crying. For example, seeing a loved one in distress can trigger tears. However, blind individuals rely more on auditory and tactile cues to understand and respond to their environment. This does not mean that blind people cannot cry due to emotional reasons; it just means that their emotional responses might be triggered by different stimuli.

### The Case of "thetj87"

The statement from "thetj87" suggests that they can cry but have difficulty producing "proper tears." This could be interpreted in a couple of ways. It might mean that they experience the emotional urge to cry but find that their lacrimal glands do not produce tears as readily as they might expect. Alternatively, it could be a subjective feeling that their tears are not as effective in providing the emotional release that sighted individuals might experience. It's important to note that individual experiences can vary widely, and this statement might not be representative of all blind individuals.

### Conclusion

In conclusion, blind people can indeed cry. The production of tears is a physiological process that is not dependent on the ability to see. Emotional crying is a natural response to a variety of stimuli, and while blind individuals might experience this differently due to the lack of visual cues, they are still capable of the emotional and physiological response of crying.
