It is mandated that a contact lens prescription must be renewed and re-evaluated by an eye doctor annually. This is to ensure your corneal health remains intact and can continue to tolerate contact lens wear. Contact lenses are a medical device, we can detect changes to your eye health due to the device that are early signs of problems that can arise in the future. If issues with the cornea are ignored, it could cause a permanent problem with vision changes or inability to wear contacts. Preventative care is why we are here for you and your contact lens needs.
