Quite mild product, I clean the lenses with a solution containing exclusively hydrogen peroxide. However, with that, you cannot take them out of your eyes, put them in the solution for a while to hydrate, and then put them back directly because if you put them in fresh solution, you have to wait 6 hours, while if you put them in the solution they have already been cleaned with, there may be residues. You can use this directly in the eye as drops if you want.

I have been using Renu for the past 16 years and I have never had the slightest problem or complaint. I have tried twice as expensive "higher quality" solutions, but I didn't notice any difference. So, consistently with this one: Value for money.

Average liquid, in no case what the reviews present, after 4-5 hours the discomfort begins with the lenses. The Bio True from the same company is superior in class.

One of the best contact lens solutions. I used OPTIFREE REFRESH for years and decided to try something a little more affordable. Excellent solution that doesn't sting the eyes and keeps the lenses hydrated all day long!
Update: After 1 year, I have to say, I wear my lenses from morning till late at night without any discomfort and without them drying out. I have been wearing contact lenses for 15 years and this is the only solution that doesn't bother me throughout the day.

I believe it is one of the best contact lens solutions I have tried, and although it is more expensive, I was not as satisfied as with renu
