Theatrical red contact lenses will typically last between 1 and 3 years, but a big factor is how well you take care of them, and how often you put them to use.
Some of the important factors in taking care of your red contacts to make sure they last longer is to keep them in solution when you aren’t wearing them, not pinching them when you are taking them out of their container, and when you first get them, removing them gently out of their packaging.
Each manufacturer will package them different, so it’s important not to just rip open the packaging when you get them so that you don’t risk tearing or ripping them. As I’ve stated before, if you feel that your contacts are damaged in any way, you should not wear them.
If you damage your new red contacts you should contact where you bought them from and find out information on their return and warranty policies.
