The common causes of 4.6 vision include refractive error, cataract, fundus disease, etc. To restore normalcy, glasses and surgery are required according to the specific cause of the disease.
1. Refractive error: Refractive error can lead to vision loss, such as myopia, hyperopia, astigmatism, etc., which can be clarified through optometry, and the use of frames or contact lenses can restore normal vision.
2. Cataract: Most common in the elderly, often due to ageing, resulting in clouding of the lens and vision loss, can be treated by ultrasonic emulsification plus IOL implantation surgery, usually vision will return to normal.
3. Fundus diseases: When macular degeneration, retinal vein occlusion, diabetic retinopathy and other fundus diseases occur, the progress of the disease can be controlled by medication and surgery, and it is more difficult to restore vision.
When vision loss occurs, you should consult a doctor in time to clarify the cause and standardize the treatment under the doctor’s guidance.
