Can blind people cry?
The answer to this question is, “yes.” However, the process of crying can be different for a person who is blind. If you are interested in how it works, then keep reading! Blind people still have the same types of tears as sighted people.
The eyes produce a type of liquid called “basal” that acts to protect and lubricate the eye’s surface. As we get older, basal production may decrease causing dry eyes- which can lead to more than just some stinging or discomfort!
Basal is also essential for maintaining healthy corneas and good visual quality.
Crying triggers two responses: Reflex tearing from our lacrimal gland (the tear duct) in response to irritation or exposure to irritants like smoke; and emotional crying triggered by intense emotions such as sadness, anger, fear, joy etc.
When someone cries due to emotion it is often because they are feeling overwhelmed with their feelings.
