United’s effort is “the equivalent of someone with vision loss doing an online vision test, making a diagnosis themselves and ordering their glasses,” Dr. Hillman said. “What if they had glaucoma? What if they had macular degeneration? What if they had diabetic retinopathy? The vision test may come out the same as someone with normal vision loss. There is a reason why people getting glasses are not able to do it online. The same should hold true for hearing aids.”
