your eyes are brown. your mates eyes are blue or green.
us sky-eyed people are a dead give away when high.
also if you puff skunk red-eyes get worse - instead puff milder organically
sunlit grown stuff - easier on the eyes.
Also stalks must be removed as they add to red-eye.
Its a mild allergic reaction I think, rehydrating your eyes by washing your face helps too. Also just drink some water...
