How often should contact lens wearers get an eye exam?

If you are wearing contacts, you should do an eye check-up annually. Your prescription will usually remain valid for a year. Without updating it, you cannot buy new contact lenses. An eye exam every year will make sure that your contact lenses comply with your current prescription and are efficient in correcting your refractive error. If your current lenses make you uncomfortable, you might be in need of a lens of different power.Since your prescription expires after that, you need to check if your lenses are still effective in correcting your refractive order or have to be changed. In addition, since your contacts cover a part of the eye, the oxygen supply to the cornea is partially cut off. Regular check-ups will help determine if that is leading to harmful consequences.
