Allergies

Helps my allergy eyes
Even though this product does not have an anti-histamine in it, like some over the counter drops, it really does make my eyes feel better and less dry and itchy. I would highly recommend it for this. My only complaint is that the design of the eye dropper makes it harder to get the drops into my eyes. Instead of having a more protruding narrow end, the area around the dropper is more flat and sometimes the drops get caught on that area before they get into my eye. The price is high enough that I really don't like wasting drops.
The drops are ok but I don't like the eye dropper they come in
The first time I used them, these drops were very hard to squeeze to get drops out. Since then I've had a couple others that weren't quite as difficult to get drops out. The one I have right now is awful. I have to squeeze it so hard because nothing is coming out and then it squirts out and I don't want it to squirt it into my eye. So now I feel like I need to get at lease a wasted drop out (to make sure that it is not going to squirt) an then hold it to my eye. I have wasted so much of it that I need to reorder again already.
pretty good
Seems pretty effective at relieving dryness. I appreciate that it feels soothing. Vision is a little blurry for half a minute afterwards. Bottle is hard to squeeze.
Best eye drops
I originally purchased the Optase Allegro Eye Drops from my eye doctor. They really helped me a lot so, I ordered another bottle. These eye drops are great since they not only help with eye allergies but, they help with dry eye too. I will purchase a third bottle when needed. I highly recommend.
My current favorite
I am a repeat buyer of this because I have MCAS and chronic dry eye, so this is the only stuff that I don’t react to other than Eyeganics but this actually lasts a bit longer, costs less, and seems to prevent irritation from allergens too.
Good drops, but pricey
Not a lot for the price you're paying, but they're definitely good at providing quick relief and work well with contacts. Would recommend, but you could probably find a cheaper alternative
Great product!
First allergy eye drop I’ve ever used that actually hydrates my eyes. Feels very soothing . Will be reordering.
