The term that refers to the inability to see objects clearly without corrective lenses is refractive error. This condition occurs when the shape of the eye prevents light from focusing directly on the retina, resulting in blurred vision. Refractive errors can manifest in various forms, such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Each of these conditions may require corrective lenses, such as glasses or contact lenses, to help focus light properly onto the retina and improve visual clarity.

Amblyopia is a different condition that involves the brain not fully processing signals from one eye, often resulting in reduced vision in that eye, but it does not specifically refer to clarity without corrective lenses. Photophobia refers to a sensitivity to light, which does not pertain to clarity of vision. Hypersensitivity generally describes an exaggerated response to external stimuli and is not related to visual clarity. Therefore, the best choice to indicate the inability to see objects clearly without corrective lenses is indeed refractive error.
