Oculus Curae Aqua Naina Saline Solution – Preservative-Free Sterile Rinse for Soft, Hard & Gas Permeable Contact Lenses – Unisol 4 Alternative – Travel-Friendly –12 x 4 fl Oz Bottles

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.

I love the size and convenience of these bottles. Larger bottles are hard to use for me with smaller hands when cleaning my contacts. These work great and pack for travel!

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 preservative free saline solution in the 4 ounce bottle works just fine with my gas permeable lenses. I gave it four stars because although they come with plastic wrapped around the top as a seal, it’s not actually sealed. You can twist the cap and pull it right off without taking the plastic off.

Good for travel

I bought this because my go-to solution, PuriLens, was out-of-stock with no timeframe when I could get it. I originally used Unisol 4 until they stopped making it back in 2015-ish. I wear sclearal lenses so I need something that is preservative-free. I was a little hesitant to buy it since some of the more recent comments indicated that the package arrived "wet", and upon further inspection, the buyers found the bottles leaking. Luckily, that was not my case. The bottles came with the top wrapped in plastic, much like you find on eye-drops, as opposed to a twist-cap that is used to break the seal (like Purilens). I would buy this product again. I would also buy Purilens again, and even Unisol 4 if they were to make it again.

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.

These are very good saline. I use them for me Scleral lenses. I used another brand that was a bit more expensive but I like this a bit better. For one they are more affordable and the bottle is great to use. There are no accidental spills.
