Very high quality and value over Purilens. Will not be disappointed.

Tom Kansas CityJuly 9, 2024✓ Verified purchase

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. Read more

Great size

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! Read more

Good product

karen cantyJanuary 23, 2025✓ Verified purchase

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! Read more

Works well for my gas permeable contact lenses

KPorto28January 15, 2026✓ Verified purchase

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.

Great value

Odane A.October 23, 2025✓ Verified purchase

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. Read more

Oculus Curae is on par with Purilens

PesopusherSeptember 29, 2025✓ Verified purchase

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. Read more
