What does skiascopy mean?
Skiascopy, also known as retinoscopy, is a diagnostic technique used to objectively determine the refractive error of the eye. This method involves shining a light into the eye and observing the reflection to assess vision. Skiascopy is a valuable tool for eye care professionals, including ophthalmologists and optometrists, as it allows them to accurately diagnose and correct vision problems such as myopia, hyperopia, and astigmatism. The technique is particularly useful for assessing the vision of children and individuals who are unable to participate in subjective vision tests. By using skiascopy, eye care professionals can provide accurate prescriptions for corrective lenses and other vision treatments.

Etymology of skiascopy
The term 'skiascopy' originates from the Greek words 'skia', meaning 'shadow', and 'skopein', meaning 'to see'. This etymology reflects the technique's reliance on observing the shadow or reflection within the eye to assess its refractive error. The term has been used in ophthalmology since the late 19th century.
