What is a 4.4?

Vision of 5.0 in normal adult eyes is normal. Vision of 4.4 indicates decreased vision, but it does not specify the degree of the eye. There is a disproportionate relationship between uncorrected vision and the degree of myopia in the eye. Myopia, astigmatism, and hyperopia can all cause decreased vision. Moreover, myopia and astigmatism can coexist clinically. After showing a decline in vision, you need to go to the hospital in time for optometry to determine whether there is myopia, and at the same time, you can determine the specific degree of myopia, and wear glasses of appropriate degree according to the results of the examination. For the elderly, the decline in vision does not rule out cataract caused by cataract. Cataract is mainly lens opacity, mainly manifested as progressive vision decline, and can be diagnosed by slit lamp examination. Treatment is mainly surgery.
