A layer of membrane on the eyes of infants may be the secretion of the conjunctival sac or conjunctival edema, the causes of which are mainly incomplete development of the lacrimal duct, conjunctival inflammation and so on. Inadequate development of the tear duct in infants, for example, there is a layer of membrane below the nasolacrimal duct that is not open normally, which can cause partial blockage of the nasolacrimal duct, which induces dacryocystitis, resulting in more secretions from the conjunctival sac, resulting in a layer of membranous manifestations in the eyes. Infants with weak immune resistance, conjunctival infection, allergic inflammation, there will be increased secretion, conjunctival edema and other manifestations, making the eyes appear to have a layer of membrane. If you find a layer of membrane on the eyes of infants, you should consult a doctor in a timely manner, do not take the initiative to deal with, so as not to delay the condition. Pay attention to eye hygiene on weekdays, rationalize the diet and avoid overwork.
