This can vary on the manufacturer and quality of the yellow contacts, but typically you can expect the yellow contacts your purchase to last anywhere from one to two years, possibly longer if you take good care of them. Taking proper care of your yellow contact lenses will make a big difference on how long they last you before you have to purchase another pair. Yellow contacts can be costly so taking good care of them is crucial.
You should avoid pinching the yellow contacts when removing them because when they are folded like that, it causes them to weaken down and will usually lead to breaking or tearing eventually.
Also when you handle them when you first buy them make sure you take them out of their packaging properly. Many times your yellow contacts will come packaged securely so they weren’t damaged during shipping and you might be in a rush to take them out. Just make sure you take your time and don’t dig them out roughly or you might cause damage immediately.
As with standard contact lenses, your yellow contact lenses should be kept in solution when you aren’t wearing them so they don’t dry out. You should change your contact lens solution about once a month while they are stored.
If you start to feel discomfort when wearing your yellow contacts you will want to inspect them for any damage because it’s crucial that you don’t put in and wear damaged contacts because it can cause long term damage to your eyes. If you suspect your yellow contacts are damaged, worn or tore, you should not risk it and should start looking into replacing them.
