白内障是双眼都会发病吗
Generally, cataracts do not necessarily affect both eyes; they may occur in both eyes or only in one eye.

Cataracts are an eye condition characterized by reduced transparency of the eye's lens, typically manifesting as blurred or cloudy vision. Cataracts do not always develop simultaneously in both eyes—they may progress synchronously in both eyes or occur independently in just one eye. Bilateral cataracts often result from similar causative factors affecting both eyes, such as aging, prolonged exposure to sunlight, genetic predisposition, and certain medications. These factors can simultaneously impact the lenses of both eyes, leading to cataract development in both, particularly as age increases, thereby raising the likelihood of bilateral cataracts.
Cataracts can also affect only one eye, which may be related to individual eye injuries, asymmetric disease progression, specific genetic tendencies, or localized environmental factors. Sometimes, the lens of one eye may experience specific stimuli or trauma, making it more susceptible to cataract formation, while the other eye remains unaffected.
If diagnosed with cataracts, patients may follow medical advice to use medications such as faropinol eye drops, pirenoxine eye drops, or glutathione tablets to help prevent further progression of the condition.
