When I first started wearing hard contact lenses, one of the biggest pain points for me was having to spend time manually cleaning them every day. This would involve holding the contact in your hand and “scrubbing” it with your finger in running water. I found this process time-consuming and a little nerve-wracking, as I was afraid I would accidentally drop my contact down the sink.
Later, I found ClearCare, which uses a special case and cleaning solution to automatically clean the contacts throughout the day. Specifically, they use a hydrogen peroxide solution and a catalyst for decomposition, so that the contacts are exposed to a stream of “scrubbing” bubbles. The case is small, so I can carry it around with me when I travel, and it automates the cleaning process for me.
