Question 1

How does this compare with refresh plus?

Accepted Answer

I put the differences in parenthesis. I can't attest to how much  better one works as the extras might be so little they're insignificant. Quite often companies add ingredients to say they are in there but it's so minute it's for fluff. However, I do not know the levels added here but because it's listed as "inactive" here so that means it does not have therapeutic properties in it, so the big difference is the glycerine. 
Carboxymethylcellulose sodium (0.5%)
Eye Lubricant
Glycerin (0.9%)- Not in the Plus
Eye Lubricant
Active Ingredients: Carboxymethylcellulose Sodium (0.5%) (Eye Lubricant), Glycerin - 0.9 % (Eye Lubricant)
Inactive Ingredients: Boric Acid, Calcium Chloride Dihydrate, Erythritol, (Levocarnitine-,used to treat carnitine deficiency)  Magnesium Chloride Hexahydrate, Potassium Chloride, Purified Water, Sodium Borate Decahydrate, Sodium Citrate Dihydrate, and (Sodium Hyaluronate- A form of hyaluronic acid-used to retain moisture), May Also Contain Hydrochloric Acid and/or Sodium Hydroxide to Adjust pH

and Refresh Plus:
Active Ingredients Carboxymethylcellulose sodium 0.5%.
 Purpose: Eye lubricant. Inactive Ingredients Calcium chloride; magnesium chloride; potassium chloride; purified water; sodium chloride; and sodium lactate. May also contain hydrochloric acid and/or sodium hydroxide to adjust pH.

I will say the plus is a waste of money if you have significantly dry eyes, not just screen irritated. If you have mildly dry eyes the plus is super cheap at big box bulk stores.

Question 2

Can you use this while wearing contact lenses?

Accepted Answer

According to the instructions, you're supposed to wait 10 minutes after inserting a drop before you put in your lenses.

Question 3

Does it makes sense to get the single use ones, if I rarely get dry eyes? I'm talking maybe a couple times over a couple years.

Accepted Answer

I use the individual containers because they are sterile and I have very poor eye sight. I’ve under a doctor’s care and he recommended individuals. I’m allergic to preservatives.They are sealed quite well. Only way to go for me but they are expensive.

Question 4

There is enough in the vial to use maybe four tines throughout the day. Is that ok?

Accepted Answer

I only get enough for two treatments a day.
