The only small problem I have is that if the liquid accidentally spills a little outside (even just a drop), then that part sticks as if Coca-Cola has spilled on it... a strange thing. Of course, other liquids do this too.

Quite a mild product, I clean the lenses with a liquid with hydrogen peroxide exclusively but that one takes 6 hours in the special case.

I use this to hydrate them during the day, I take them out of my eyes for a while, put them in the liquid for a little while, and then put them back on.

There are better liquids, but this one was on sale.

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 solutions for contact lenses. I used OPTIFREE REFRESH for years and decided to try something else a bit more economical. Excellent solution that doesn't sting the eyes and keeps the lenses hydrated all day! Update: After 1 year I have to say, I wear lenses from morning until late at night without any discomfort and without them drying out. I've 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
