Bought based on reviews and recommendations. They didn't fit. It is impossible to work in them - the eyes dry after 30 minutes of wearing. Apparently, due to dryness, they simply fell out of my eyes, I had to carry additional lenses with me in reserve just in case. The lens itself is very thin. In the box 30% of the lenses are defective. Maybe it happened to me personally. I will return to Alcon, I could not save.
