I eat HFLC.
I'm also on a very high strength diuretic for medical reasons. It CAN cause dry eyes issues, along with other mucous membrane dryness issues.
I do NOT have dry eye. Nor any other dry mucous membranes.
If low carb caused dry eye, then surely I would have it since I also take a medication known to cause it in conjunction with "LC causing" it. Essentially I should be getting a double whammy if that thinking were true...
There is no actual proof that LC causes dry eye.
Just one guy whose eyes felt dry, who decided to blame it, who also happens to be a guru...
Look into actual reasons please instead of buying into these ridiculous assertions.

Not saying you have to stay LC either...
What ever you feel like.
I just think it's not the best idea to take the whole "my eyes were dry and this is what I think caused it" as FACT just because a dude you like says it (Jaminet).
Often when people change their diets they become hyper aware, watching and waiting for any sign of change from their body and attributing it to a specific thing in their diet whether that is correct or not... it's over-reaching and annoying when others quote it as fact later.
