It's my first time trying contact lenses, so I did a lot of research on which brand to use, and Olens was the most recommended. I chose Vivi Ring Gray because it's natural, but I still wanted a change in my eye color without it looking unnatural or scary. It's also really comfortable. I used their O Fresh to store my lenses, and it works well. I wore the lenses for 6-7 hours, and they weren't drying to my eyes. Definitely recommend!
