haha funny thing.
JDiz said to google 'rohto v'. so i did.....and its says here

"Salmon is a good source of omega-3 fatty acids, which may reduce your risk for dry eyes. Sardine, herring, and cod liver oils are even better sources; or you could take a supplement."

and just in case you didnt know...hemp seed is very rich in omega -3 fatty acids and omega -6 fatty acids. i thought that was kinda funny that cannabis has the ability to give you red eye...and sounds like take it away too.

just my 2 cents.
