I have a love hate relationship with these lenses. MOSTLY LOVE! When they're at the end of their life, they take a deep, sharp decline. I wear them everyday for over 12+ hours and don't have issues. Towards the end of their life cycle, they do get dry and they get retain protein deposits BAD. They get super uncomfortable and tear while in your eye easily... I like to make sure when they're nearing the end to have eye drops and an extra set in my bag just in case. Other than that, I LOVE THEM! Long wearing, comfortable & affordable.
I have repurchased these at least 5 times.
