You may feel very weak also. Because you have to the extent times and it must effect your eye sight. So consult the doctor and say him all the matter.
Hi,
From what I've read about Keratoconus , you've got to speak with your eye doctor about further advice and treatment for this disorder.
There are sites that you may want to look at, that will give you more information about the causes, symptoms, and treatments, just type in the word Keratoconus in your search bar for access.
Masturbation and your eye pain may have been just coincidental; masturbation itself will not make you lose your eyesight.
