The hyperopia that can be overcome by accommodation is called which?

• A. Manifest hyperopia
• B. Absolute hyperopia
• C. Facultative hyperopia
• D. Latent hyperopia

Answer: (C)

When the eye has farsightedness, accommodation can be used to bring distant objects into focus. The part of that farsightedness that can be neutralized by this accommodative effort is called facultative hyperopia. It depends on how much the eye can accommodate—the more accommodation available, the more hyperopia can be offset. The portion that cannot be overcome by accommodation is absolute hyperopia, while latent hyperopia is hidden by ongoing tonic accommodation and only becomes evident if accommodation is paralyzed (cycloplegia). So facultative hyperopia is the portion that can be overcome by accommodation.
