If you wear contacts, will your eyes continue to get worse?

Yes and no. Contact lenses treat blurred vision caused by nearsightedness, farsightedness and astigmatism. These conditions naturally worsen over time in many people, and lenses are only meant to correct the vision you have. Contacts can cause other eye problems (infections, dry eye, scars, allergies) which can worsen vision, but they will not stop your natural vision changes.
