The recovery time for blurry vision caused by keratitis can vary, as keratitis can range from mild to severe. Mild cases may recover within 3-5 days, but severe cases, if complications like corneal nebula, macula, leukoma, corneal ulcers, or corneal perforation occur, may lead to difficult or impossible vision recovery, or even blindness. Therefore, it is important to take keratitis seriously in treatment. Active and diligent treatment should not be neglected. Normally, do not apply heat, maintain a light diet, avoid spicy and irritating foods, use eye drops and ointments as prescribed, attend regular check-ups, and monitor vision status.
