The Feinbloom chart is used for patients with what characteristics?

• A. Normal acuity
• B. Color vision deficiency
• C. Very poor acuity and eccentric viewing difficulties
• D. Binocular diplopia

Answer: (C)

The Feinbloom chart is a low-vision acuity tool designed for patients who have very poor visual acuity and rely on eccentric viewing due to central vision loss. It uses large optotypes that are easier to detect with peripheral vision, allowing clinicians to quantify remaining function when standard charts fail. This makes it especially useful in guiding rehabilitation for those with severe vision loss. It isn’t intended for people with normal acuity, it isn’t a color-vision test, and it isn’t a tool for assessing binocular diplopia, which require different assessments.
