DMV test 50 deg on left. Humphrey field normal. ophthalmologist thinks DMV test wrong but didn't suggest Goldman test for comparison. Should I insist?
Glaucoma rt. eye.Humphrey field test full within normal limits.DMV peripheral vision test 50 deg left & 70 deg right. Dr says DMV test wrong.Possible?

No, not always: Visual acuity is a measure of how well you see. In most cases this reflects on what your prescription might be but it can't estimate it exactly. There are many other factors that determine how well you see: if your retina is healthy and if there are other problems with your cornea or lens. It's possible to have poor visual acuity and yet have no need for glasses. ...Read more
Compared to standard: The chart used to test the eye is calibrated for normal vision at 20 feet. The outcome achieved is compared to what a normal eye can see at 20 feet. So if you can only see at 20 feet what a normal eye sees at 40 feet, your vision is considered to be 20/40. This is measured with and without corrective lenses at distance and at near. The vision with correction is considered to show the true vision. ...Read moreSee 1 more doctor answer
