Naked eye visual acuity of 5.0 means that the patient’s vision is normal.
Naked eye visual acuity refers to the ability of the eye to distinguish the details of a scene when doing a visual acuity examination without glasses, when expressed in logarithmic scale, the normal naked eye visual acuity should reach 5.0. If the patient’s naked eye visual acuity can reach 5.0, it means that the patient’s visual acuity is normal.
If the patient’s naked eye visual acuity is less than 5.0, further optometric examination is required. If the refractive error is caused by refractive error, the patient can correct the refractive error through the use of eyeglasses to improve the patient’s visual acuity. In addition to refractive error, cataract, glaucoma, retinal detachment and other diseases can also lead to vision loss, and the prescription of glasses can not improve vision.
It is recommended that patients with vision abnormalities seek medical attention in a timely manner to assess their condition and follow the doctor’s instructions for treatment.
