"Skiascopy" Natural Recordings by Native Speakers
Skiascopy refers to a non-invasive optical procedure used in ophthalmology to measure the refractive error of the eye, specifically the precise measurement of the eye's ability to focus light. It is a method used to determine the prescription for corrective lenses, such as glasses or contact lenses, by analyzing how light bends as it enters the eye. Skiascopy is commonly called orthography or retinoscopy in some countries.
Another term for ski flying, it is a winter sport where athletes jump down a ramp similar to a small snow hill and use skis to launch themselves into the air. Ideally, they would leap as far as possible from the ramp, just like in acrobatic skydives, aiming for the greatest distance without crossing into ever more successful types, such as the short takeoff ramp requirements.
