If TENNA water gets into your eyes, don’t panic. First of all, you must flush your eyes with a lot of water and go to the hospital in time to let the doctor see if there is any damage to the corneal epithelium. If there is damage to the corneal epithelium, the eye will be very painful, and there will be a lot of tears, difficulty seeing, and red eyes. In this case, if the damage is small, it can often heal by resting with the eye closed overnight; if the damage is large, hospitalization may be required. In this case, the doctor will treat the corneal epithelial damage as appropriate, possibly wrapping the eye with erythromycin eye ointment, which can significantly relieve pain and take a night to heal. If the damage is more extensive, hospitalization may be required for amniotic membrane transplantation, as well as spotting the eye with autologous blood, although the results of this are also okay.
