I performed Laser Eye Surgery (PRK) in 2009. Since then, I've inherited dry eyes that are particularly worse when I wake up in the morning. A drop of eye drops in each eye would easily fix this issue. Recently, when I began vaping MJ for the last several of months (on a near daily basis), it appears my dry eyes condition has gotten worse. My eyes are evidently drier than before when I wake up in the morning; I need to use at least 4, sometimes as much as 5 drops, in each eye to properly lubricate it. Is there anyone else that's in the same boat as me? Is this something that I should be worried and go see a doctor about? I vape in the afternoon sometimes, my eyes do not get dry after. It only gets incredibly dry in the morning, when I vaped the night before.
