What is naked vision?

Uncorrected vision refers to vision that can be achieved directly by the naked eye without wearing glasses. Normal adults with uncorrected vision of 5.0 are normal, and vision that is lower than 5.0 is reduced. Vision achieved by wearing glasses or wearing contact lenses is called corrected vision. Corrected vision can reach normal, indicating that there is refractive error. In addition, if fundus disease or cataract can cause naked eye vision decline, it is suggested that as long as naked eye vision is reduced, it is necessary to go to the hospital in time. After optometry, fundus examination and slit lamp examination, the cause of vision decline can be clarified, and symptomatic treatment can be carried out according to the examination results.
