Patients who feel a layer of fog in their eyes after removing contact lenses may be caused by corneal epithelial hypoxia and edema or corneal epithelial damage.
If the patient continuously wears contact lenses, because the wearing time is too long, it may be because the contact lens impedes the cornea to take up the oxygen content in the air, which leads to corneal hypoxia, triggering corneal epithelial edema, which leads to the symptom of foggy eyes after the patient removes the glasses. Patients need to stop wearing contact lenses temporarily to promote the recovery of corneal epithelial function.
When removing contact lenses, if the patient’s fingernail accidentally scratches the cornea, resulting in corneal epithelial damage, can lead to corneal edema, which can also lead to the patient to see things as if there is a layer of fog. Patients need to suspend wearing contact lenses and follow the doctor’s instructions to use drugs to promote corneal repair, such as recombinant human epidermal growth factor eye drops.
It is recommended that patients who experience eye discomfort after wearing contact lenses seek prompt medical attention to evaluate their condition and follow doctor’s instructions for treatment.
