The sensation of water in the eyes mainly reflects the accumulation of excessive tears in the conjunctival sac, which is caused by two factors. It may be caused by environmental factors, or it may be caused by bad eye habits, or by the decline of hormone levels in old age, which causes dry eye symptoms. The main treatment for this is: 1. Avoid irritating environmental factors; 2. If you have some dry eye symptoms, you can use artificial tears to relieve them, so that you can reduce the irritation of the eye surface. Another factor that can cause the accumulation of tears in the eye is the obstruction of the tear drainage channel, which means that there is a narrowing of the tear ducts, which can be seen in inflammation of the tear ducts, or the weakening of the tear siphon due to skin laxity in old age. If there is inflammation of the lacrimal duct, it is usually accompanied by increased secretion or redness of the eyes, and antibiotic medication is needed to treat the inflammation and relieve the narrowing of the lacrimal duct. If the lacrimal siphon is weakened due to age-related skin laxity, it is essentially a sign of aging, so there is no specific treatment.
