Q: How can contact lens wear be a risk?
A: Contact lenses are considered a medical device, which can put you at risk for serious eye infections
Q: Why does a contact lens prescription have a specified expiration date?
A: Because the doctor must evaluate the health of your eye, to make sure that contact lens wear is safe for you. If your eye health is being compromised by contact lens wear, then the doctor can’t give you the prescription or must set the expiration date accordingly.
Q: How would the health of my eyes be compromised?
A: If your eye doesn’t breathe properly due to the contact lens, blood vessels can grow onto the cornea. Other complications are alternations in your corneal cells, inflammation of the cornea, thinning of the cornea, and reduced corneal sensitivity. With any of these problems, you must discontinue or decrease contact lens wear. The doctor may find another contact lens that will minimize these complications. Eventually, these problems can lead to contact lens intolerance, where you will not be able to wear your contact lenses any longer.
Q: How can I know if my eyes are being compromised by contact lens wear?
A: By a physical examination of your eyes. Just because you are an established contact lens wearer or do not have symptoms does not mean contact lenses are safe to wear! And a “selfie” of your eye is not enough to determine whether your eye health is being compromised by contact lens wear.
