Dr. Arbet was just as interested in providing these new Bio Sport tinted contacts as I was in wearing them. They work great, but I am still learning to put them in because they are larger than most contacts and cover not only the pupil, but also some of the whites of the eyes as well. Not a simple task for a first time wearer, but the results on the field make it worthwhile. I don't think the office assistant had seen these contacts before either, because she thought I would be able to put them in my eyes the first time out. Again, contacts this large takes practice to become comfortable with insertion, but the trade off in seeing the ball so much better makes it worth the effort.
