Opti Free Replenish is a sterile, buffered, isotonic solution which contains sodium chloride, sodium citrate, sodium borate, propylene glycol, and the TearGlyde dual-action reconditioning system. It has Polyquad (polyquaternium-1) 0.001% and Aldox 0.0005% preservatives. In general, Opti Free Replenish is actually gentler.

On the other hand, the ReNu fresh multi-purpose contact lens solution contains poloxamine, Dymed, and Hydranate to cleanse the contact lenses from germs, protein deposits, as well as dirt and debris. It also contains boric acid, sodium chloride, edetate disodium, and sodium borate to enhance the wearer’s comfort.

Performance and Comfort
Both Opti Free Replenish and ReNu are highly effective in killing germs and removing buildups from contact lenses. Several studies have shown that Opti Free Replenish is able to remove more protein buildups, but it does not mean that ReNu is bad.

Opti Free Replenish is great because it is a gentler formula. It does not contain many preservatives that may irritate the eye. However, there are some people who are sensitive or allergic to its ingredients. If you experience redness or dryness with this solution, you should stop using it.

On the other hand, ReNu is relatively harsher because it contains more preservatives. Indeed, it seems to make the lenses smoother, but this is not an indicator that the lenses will be more comfortable to wear. Nevertheless, if Opti Free Replenish causes you redness or dryness, the ReNu contact lens solution can be your choice.
