Jim is a really pleasant gentleman who only needs one contact lens. He had problems in the past of not being able to clean the lens well enough due to his previous lens solution. He found that his contact lens used to rub and cause other problems. While at a hospital visit, he saw a specialist who looked over his problem. His doctor recommended AoSept as a replacement for the product he used before. Ever since then, he has never used another brand and says that for him, this works the best.
