FAQs
How do I open the PuriLens Plus bottle?
Inside the bottle cap is a molded insert that will pierce the container. To open the bottle, first remove the cap and discard the white plastic restraining ring. (This ring is only there to keep the bottle from being punctured during transit and will not be attached to the bottle itself) Avoid touching the tip of the bottle.
Replace the cap then press down and turn the cap clockwise to pierce the container. We suggest not screwing the top in too tightly or you may end up with a larger hole than you want. Re-close the bottle after use. Always wash and rinse your hands before you handle your lenses.
Discard any remaining solution 14 days after opening.
I have extremely sensitive eyes. What are the ingredients in PuriLens?
Purified water, sodium chloride (salt), boric acid, and sodium borate (used as buffers to balance the pH for comfortable use in the eye). These are the exact same ingredients that were in the now discontinued Unisol 4 and Simply Saline Contact lens solutions.
What are buffers for? Why would I want buffered vs unbuffered saline?
Buffers are there to balance the pH and reduce irritation. Buffers mimic the natural system of the tear film which regulates variations in pH. Your tears contain various compounds including a bicarbonate buffer system to compensate for variations in pH over the course of the day. There are many reasons for variation in pH, such as fatigue, the act of shutting your eyes, or wearing contact lenses. Some brands of saline (water with sodium chloride, the chemical name for salt) without buffers (e.g. LacriPure, Addipaks, Modudose, or anything that says sodium chloride 0.9% for respiratory therapy) do not contain any compensating factors. While some people do not distinguish between buffered or unbuffered saline, people with sensitive or dry eyes may experience a significant difference.
Why does the bottle appear to be not full?
Purilens bottles will not appear full to capacity. This is due to the rigidly controlled method in which they are manufactured, called blow-fill-seal. This process prevents the saline solution from coming into contact with air until the bottle has been pierced open using the mechanism within the cap, ensuring the solution’s sterility. You can be certain the Purilens bottle you receive contains either 2 or 4 fluid ounces of Purilens saline solution by weight.
