Visual acuity of 1.5 is the result of a standardized fractional visual acuity chart, which is equivalent to a visual acuity of 5.2 if converted to a standardized logarithmic visual acuity chart.
Visual acuity is an indicator of visual acuity and is one of the most basic tests in an eye examination. There are various methods of visual acuity testing, such as logarithmic visual acuity charts and fractional visual acuity charts.
If the patient’s visual acuity is lower than 1.0 on the naked eye decimal scale and 5.0 on the logarithmic scale, it means that he/she is suffering from vision loss. He/she should go to the ophthalmology department of the hospital as soon as possible to find out the reason for the vision loss, and then he/she can take the targeted treatment.
