  • How is visual acuity for both eyes determined?


    Question:

    How is visual acuity (sharpness, power) for both eyes determined? For example, if your right eye is 20/50 and your left eye is 20/150, is there a number for your overall vision at that point then?


    Answer:

    Each eye has a specific visual acuity. There is no formula to add or combine the two visions and conclude a vision for both eyes. The best way to test this is by having your vision checked with both eyes open. That will give you your visual acuity for both eyes.
