The eyedrop aisle at your local pharmacy can be scary and confusing, so let's talk about it. I have no financial interest in these products, but would LOVE to have some financial interest. Let me know where I can find some. Ok, here we go... 
First, a word about brand vs generic. They both have the same active ingredients, but different preservatives (not listed). I've found generic preservatives to induce more allergy than the brand name. Generic is still a good option, but stick w/brands if you can afford it
Refresh and Systane, royalty in artificial tear land, the most boring fictional land out of all the fictional lands.
Stay away from these two. Look at all the garbage found in @Visine. ASTRINGENT. The thing you use to help get rid of pimples. I wouldn't want that in my eyes. Clear Eyes is less offensive, but if you have red eyes, there is a reason. Go to the doctor FFS
These are also good options. One provides immediate comfort, the other immediate long lasting relief. One of them also drains into the brain and directly stimulates your pleasure centers. Not sure which one.
For allergy relief, stick with Ketotifen (Zaditor or Alaway). Naphcon is just Visine with a shittier name.
If drops aren't cutting it and you want longer relief, you need something thicker. Celluvisc is my favorite and it's preservative free. Blurs up the vision temporarily. It was on sale today.
Finally your nighttime gels and ointments. Lube up those lookingballs before bed. You won't be able to see anything and might fracture a hip getting to the bathroom in the middle of the night, but your eyes will feel great!
