I stopped using eye drops, only in times of true need. Cause then you can't look in the mirror and say "holy shit I'm so fucking high right now my eyes are so damn red". Wear sunglasses or come up with a good excuse
Try getting an eye lubricant like Thera Tears...it feels and works great. I also switched to it for my allergies to help with the itchy and runny eyes..There are generic versions for a lot less $$..Mine came from CVS in the USA.
