The lenses are very easy to use, easier than the last, which I had, and have, in my opinion a good quality (I'm no expert!) I wear them every evening for sports, take them out then, put them back in their shells, syringe 5 contact lens solution from DM pure, so they do not dry out, and can use it the next night again. Does that but on your own risk. I am an engineer and not a doctor or optician.
