I've been wearing clear prescription daily contacts for 3 years, so I'm familiar with putting them on, hygiene, etc. Since these contacts are more durable, I didn't think the material would be comfortable. However, they feel great and it takes some getting used to. My eyes are naturally a very dark brown, and there was a visible color change, and I am very happy with it and plan on buying more! This is my first experience with TTDeye products, and I also liked the fact their contacts are FDA app...
