What is the endpoint of Bulls Eye accommodative rock?

• A. Clear bulls eye to distance equal to their average amplitude
• B. Clear bulls eye to 40 cm
• C. Clear bulls eye to 20/20 at 50 cm
• D. Maintain fusion throughout

Answer: (A)

The key idea is that the Bulls Eye accommodative rock ends when the target is cleared at the distance that matches the patient’s own average amplitude of accommodation. In other words, you push the eyes to focus on a nearer target until the demand equals the person’s typical near focus capacity, then mark that distance as the endpoint. Since amplitude of accommodation is measured in diopters, the endpoint distance is the inverse of that value (for example, about 10 diopters corresponds to roughly 10 cm). This makes sense because the exercise is about training and testing how far the eye can comfortably accommodate rather than using fixed distances. Fixed distances like 40 cm or 50 cm don’t reflect the individual’s actual accommodative ability, and simply maintaining fusion concerns binocularity rather than the amplitude endpoint.
