Wearing contacts can cause corneal hypoxia and vision issues

Many people enjoy wearing contact lenses for their convenience and look, but they may not know about a serious condition that can arise from them. An eye doctor has warned that wearing contacts can lead to corneal hypoxia, a problem where the cornea does not get enough oxygen. The cornea is the clear front part of the eye, and it relies on the air, tears, and other fluids for oxygen since it does not have its own blood supply. When wearing contacts, this oxygen supply can be reduced. Symptoms of corneal hypoxia include itchy or irritated eyes, redness, pain, and even decreased vision. It is important to see a doctor quickly if you notice these symptoms. Ignoring them could lead to more severe issues like inflammation, infection, or scarring. One woman shared her experience of cloudy vision attributed to older contact lenses and planned to change brands after her eyes healed. Treatments often involve taking a break from contact lenses and using lubricating eye drops. In severe cases, surgery may be needed. To prevent corneal hypoxia, doctors recommend using lenses that allow more oxygen to reach the cornea and following proper lens care. For those who wear contacts, the American Academy of Ophthalmology suggests following good hygiene practices.
