In general, conjunctival congestion can be recovered in about 5-10 days, but the exact time depends on the severity of the congestion and the cause of the disease. Conjunctival congestion is mainly due to capillary rupture, and the specific causes include staying up late, drinking alcohol, conjunctivitis, trauma, and coagulation dysfunction. If the conjunctival congestion is caused by staying up late or drinking alcohol, it can recover in 3-5 days after rest. For small amounts of conjunctival congestion caused by trauma, conjunctivitis and coagulation dysfunction, it can be absorbed in about 7-10 days after active symptomatic treatment and control of the original disease. If the conjunctival congestion is more severe and dark purple in color, it may take about 3-4 weeks to recover from this condition. Patients with conjunctival congestion must pay attention to rest, reduce the time spent with the eyes, look less at cell phones, computers, etc., and reduce the congestion by applying cold compresses within 48 hours of the conjunctival congestion.
