The hyperopia that cannot be overcome with accommodation is known as which?

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

Answer: (B)

Accommodative reserve has a limit, which is the amount the eye can increase its refractive power to offset hyperopia. When hyperopia exceeds this reserve, even at maximum accommodation the image still falls behind the retina. That portion cannot be overcome by focusing, and it is called absolute hyperopia. Latent hyperopia is hidden by the eye’s resting accommodation and only shows up with cycloplegia, while facultative hyperopia can be offset by accommodation for near tasks.
