During treatment for infectious pink eye (conjunctivitis), you'll be advised to temporarily stop wearing your contact lenses. It's OK to start wearing your contacts again once you've completed your antibiotics, your eye is no longer pink and you've had no discharge for 24 hours.
After treatment is complete, your doctor will likely recommend that you throw out contacts you've worn if your lenses are disposable. This can save you from getting a repeat infection.
If your lenses aren't disposable, disinfect them overnight before reusing them. Don't forget to double-check the expiration date on your lens disinfection solution to be sure it's still effective. Ask your doctor if you should discard and replace your contact lens accessories, such as the lens case used before or during the illness.
