Very good product regarding eye moisturization. The drops are quite 'light' for more lubrication (but also blurriness - especially with contact lenses), prefer the 0.4 (or another product with more hyaluronic acid). A big negative is that the bottle has a mechanism that does not allow air to enter (for protection against infections). So as you put drops, the bottle 'jams'. In the end, there is still a lot of product left but you cannot squeeze it further to get the last drops out. Unfortunately, a lot of product is wasted for this reason.

The eye lubrication does not last long enough. I am still trying to find a product that provides longer hydration

I am not particularly satisfied compared to others. Moisturizing and lubrication are more limited these spring days when I need them daily. Also, my eyes do not rest particularly when I put drops before sleeping... always in comparison to others.

Excellent product, I would prefer it in bottle packaging or in a more affordable version (at intervals)

The best thing, effectively helps with dry eyes, can be used on eyes with contact lenses.
