I've been vaping about 7 months now. Within a month of starting I noticed my eyes were dry and itchy. I figured it was allergies and went to my optometrist. She gave me some anti-inflammatory eye drops and some artificial tears. Some of the symptoms subsided over time but I still was experiencing dry eyes and had to always use the tears. I was checked by an allergist and he found no sensitivity to any of the usual suspects. About 3 weeks ago I suddenly got a massive black spider web floating about in the right eye right in my sight line. Back to the eye doc and she said it was a "posterior vitreous detachment" caused by old age. I'm only 64, not even old enough for old age pension. She said the symptoms would subside somewhat in 4 to 6 weeks. I'm still waiting. Yesterday I developed a floater of about the same size in my other eye again in my field of view. Off to see the eye doctor again! Does vaping cause this? I realize that the PG in vape is an alcohol and can be irritating to the eyes. At the first signs of dry eye (6 months ago) I switched to 80/20 juice but this hasn't stopped the worsening eye condition. Maybe I should give up vaping. What do you all think? Anybody else having similar problems?
However the dry eyes IS a problem from vaping, just because vaping is dehydrating. Using higher Vg is no solution; VG is every bit as hygroscopic as PG, it just also has an emollient effect, so you don't notice the dry mouth/throat as much -- which makes it worse, in my opinion, since the only cure is to consume more non-caffeinated and non-alcoholic liquids, and if you don't notice the dry mouth/throat as much, then you won't consume them. Drink more water, drink more juice, drink more everything that doesn't contain caffeine or alcohol, both of which will worsen the dehydration problem -- caffeine is diuretic, and alcohol displaces water.
