I wear contacts that correct my astigmatism. They are Proclear toric, you can wear them all day but can't sleep in them. They are good for a month then you put in new ones. The doctor had me try the purevision and they were very comfortable but I stayed with Proclear because I've been using them for the past couple of years and with my doctor if you try a different brand and decide to go with them he charges you a fitting fee.
