Long-term contact lens wear can lead to dry eye, conjunctivitis, keratitis, and even acute bacterial corneal ulcers, which can lead to corneal perforation in severe cases. Therefore, when wearing contact lenses for a long period of time, you can apply prophylactic medication to prevent infection, such as levofloxacin eye drops or tobramycin eye drops, one drop three times a day. If you experience eye congestion, foreign body sensation, photophobia, or tearing after wearing glasses, you should stop wearing contact lenses and go to a regular eye care provider for appropriate examination to avoid delaying the condition. If you experience dry eyes, you can apply sodium glassate drops, one drop each time 4 times a day, to reduce eye dryness and discomfort caused by contact lenses.
