vision problems associated with menstration

Hello! I have a problem, actually not a problem, that is bothering me... I am just curious. I feel sometimes that I can see things more clearly; I have some problems with eyes, and should be wearing glasses, but not... But sometimes I feel like I see things much more clearly than usual and do not need to focus vision, for example. This is associated with my menstration, I think.

Hey!
You are very right! Good observer!
Lots of studies show that woman's vision and sense of smell are heightened at ovulation - this is because of estrogen! The same happens right before menstruation – this is because progesterone levels drops and leaves estrogen to act “uncontrolled”.
