Some rigid types of contacts can be kept for years before being replaced with newer ones and this is very cost effective for anyone exclusively wearing contacts, but the initial cost is obviously higher for this reason.
Financially, the rigid contacts are always cheaper if you can get used to them. The last advantage is that the durability of the material often gives better vision clarity than the soft contact lenses.
Soft contact lenses, on the other hand, can never be worn for such long periods of time. You can choose from daily, weekly and monthly varieties of soft lenses, but none that will last you any longer than that. Their main advantage over the rigid lenses is the fact that they are easily adapted to and cause very little initial discomfort. They are made of a very high percentage of water [between twenty five to almost eighty percent].
