What about Vision 4.9?

In general, it is recommended that patients with vision 4.9 go to the hospital for examination and take appropriate treatment measures in time after clarifying the cause. If the cause of the patient's vision 4.9 is myopia, hyperopia or astigmatism, only glasses can be used; if the vision 4.9 is caused by cataracts, the corresponding cataract treatment drugs must be used, and the patient needs to pay attention to anti-aging.
