is there any difference in the visual acuity of men and women of the same age [statistically speaking] and....

Question

.....is there any consequence for eye health, of someone never crying/getting tearful, as opposed to someone who cries or gets tearful on a regular basis...whether through laughter or feeling sad, upset etc.

...ie: is there anything unique in the compostion of cried tears, as opposed to the substance that lubricates your eyes through the day?

Answer 1

First part: yes. Men are typically near-sighted (see clearly up close, need glasses for far-off, such as driving or playing golf). Women are typically far-sighted (see clearly at a distance, need glasses to read or sew).
Second part: no difference, unless it is an extreme. Dry eyes is an eye condition; however, a person who seldom cries or has tears (tearing is a milder form of crying; it is normal for the eye to produce tears, which is how it stays moist) does not necessarily have dry eyes. However, a person who produces too many tears will be bleary-eyed.

Answer 2

A lot of older women develop dry eyes as a symptom of menopause. It has nothing to do with how much they cry or not but more to do with fluctuating hormone levels.

Answer 3

I reckon women must have more productive tear ducts.

Answer 4

wouldnt have thought so. maybe you should ask an optician
