How Many Eyelashes Do Humans Have?170

Eyelashes are an important part of the human body, protecting the eyes from dust, debris, and other irritants. They also help to keep the eyes moist and lubricated. But how many eyelashes do humans have? The answer may surprise you.

The average adult has between 90 and 150 eyelashes on each upper eyelid and between 70 and 100 eyelashes on each lower eyelid. This means that the average person has between 180 and 250 eyelashes in total. However, some people have more or fewer eyelashes than average. For example, some people may have as many as 200 eyelashes on each eyelid, while others may have as few as 50 eyelashes on each eyelid.

The number of eyelashes a person has is determined by genetics. However, there are some factors that can affect the number of eyelashes a person has, such as age, gender, and ethnicity. For example, women tend to have more eyelashes than men, and people of Asian descent tend to have more eyelashes than people of European descent.

The number of eyelashes a person has does not affect their vision. However, people with fewer eyelashes may be more susceptible to eye irritation and infection. This is because eyelashes help to protect the eyes from dust, debris, and other irritants.

If you are concerned about the number of eyelashes you have, you should talk to your doctor. They can help you determine if you have an underlying medical condition that is causing you to lose eyelashes. They can also recommend treatments to help you grow more eyelashes.
