Does cataract always get worse?

Introduction
In general, whether cataracts will progressively worsen depends on the type of cataract, the patient's overall health condition, and whether any interventions are taken. Wear sunglasses when going outdoors to reduce ultraviolet damage to the lens. Ensure adequate lighting when reading and avoid prolonged close-up visual tasks. Control fundamental health indicators such as blood sugar and blood pressure.
In general, whether cataracts will continue to worsen depends on the type of cataract, the patient's overall health, and whether interventions are implemented. A detailed analysis is as follows:
If no intervention is taken for age-related cataracts and the patient has metabolic diseases such as diabetes, lens opacity usually progresses continuously. With aging, protein denaturation in the lens accelerates, leading to gradual vision deterioration—from blurred vision to only light perception—significantly affecting daily life. Without intervention, the progression is unlikely to stop spontaneously.
For congenital or traumatic cataracts, if the condition is stable and timely treatment is provided, the cataract may not continue to worsen. In some patients with congenital cataracts, the cloudy area remains fixed without significant progression. With prompt treatment after injury and effective control of inflammatory responses, lens opacification can cease progressing. Medication or surgical intervention can effectively prevent further deterioration.
Wear sunglasses when outdoors to reduce ultraviolet damage to the lens. Ensure adequate lighting during reading and avoid prolonged near-work. Control baseline indicators such as blood glucose and blood pressure to minimize the impact of metabolic abnormalities on the eyes. Consume moderate amounts of lutein-rich foods such as spinach and corn. Schedule regular vision checkups to monitor changes in lens opacity.
