Visual acuity of 4.5, which is logarithmic recording method, is equivalent to 0.3 of decimal visual acuity, which is usually abnormal and needs to be corrected by treating the cause of the vision loss, for example, caused by refractive error, which can be corrected by wearing glasses, etc., and caused by cataract, which needs to be treated by surgery.
Under normal circumstances, vision should reach 5.0, if the current vision is 4.5, it means that there is vision loss, you need to go to the ophthalmology department of the hospital as soon as possible to find out the specific causes of vision loss, and then under the guidance of the doctor for the cause of the treatment.
For refractive error vision loss, the exact type and degree of refractive error can be determined through an optometry examination, and can then be treated by wearing glasses or undergoing laser corrective surgery.
Vision loss caused by cataracts usually requires surgical treatment, such as cataract ultrasonic emulsification suction combined with IOL implantation.
With a visual acuity of 4.5, it is recommended that you seek medical attention to complete other examinations and take appropriate corrective measures as prescribed by your doctor.
