Aqua Naina - Preservative Free Sterile Saline Solution for Contact Lenses - Unisol 4 Replacement - Contact Solution for Cleaning, Rinsing and Disinfecting Soft Contact Lenses. (4X 4Fl. Oz)

I am allergic to preservatives in contact lens’s solution. This solution works well and is a convenient size for traveling.

Long time user of Purilens. After I saw Aqua Naina come on to the market, I had to try it, and, I am shockingly surprised how much better the experience and product is over Purilens. 1st of all, the formula is much better. As where Purilens was harsher on my eyes, occasionally causing a slight irritation, burning, again, very slightly, Aqua Naina on the other hand does not have that effect on my eyes at all. Much more pleasant experience. Second, the bottle and drop applicator portion of the bottle is much better. The hole is smaller, so you waste less product. The bottle is also made of slightly thicker material, and it feels a lot more premium in the hands. It's also slightly smaller ( see my pictures ) Will never use Purilens again. Aqua Naina is 10x better in about every category.

Have bought a competing product for years, for some reason there’s a long delay shipping. Called several stores , don’t have it! So I googled for a similar product and found altos. Not only did it ship very fast but the true test was when hubby tried it as soon as I opened the box it was as good as the usual purchase. Very pleased!

This product is fine. I have no problem with the quality. My only complaints have to do in packaging. Im use to Purilens or Unisol and those products have a cap that punctures the seal on the vial. This product only has a cellophane safety seal which isnt as easy to remove. Also, Purilens and Unisol vials are more flexible which makes it easier to squeeze out the solution to rinse your lens. This is a firmer plastic.

Price was great for size and quantity of product. Love the fact it can be packed easily for travel

I must use preservative free saline with my scleral lenses. Unfortunately, there is very little competition for this type of saline. My previous brand more than doubled their price. Lucky for me, Amazon suggested a new brand that was much cheaper. It works exactly the same and keeps my eyes comfortable. The bottles come individually sealed to preserve sterility.

Fulfilled my needs well.

Love this size
