Etymology From Ancient Greek στενός (stenós, “narrow”) (see steno-) + ὀπαῖος (opaîos, “perforated”), from ὀπή (opḗ, “opening”). First attested in 1855 (see quotations) in relation to the works of Franciscus Donders, who coined the original term as Dutch stenopaeische (1853-1854).

- These patients were selected retrospectively, and only those treated with complete bed-rest and stenopaeic spectacles alone were accepted.1976 April, Thorkild Bramsen, “Traumatic hyphaema treated with the antifibrinolytic drug tranexamic acid”, in Acta ophthalmologica, volume 54, number 2:

- Stenopaeic slit refraction is usually attempted when retinoscopy and more conventional subjective refractive techniques, i.e. JCC and FC, fail to provide satisfactory results.2009, Mark Rosenfield, Nicola Logan, Keith H.

- By contrast, the more aquatic sea lion eye is emmetropic in water and depends upon a flattened cornea and stenopaeic aperture for the formation of a good image in air (WALLs, 1942; SCHUSTERMAN, 1972).2013, F. Crescitelli, The Visual System in Vertebrates, →ISBN, page 680:
