"Skiascope" Natural Recordings by Native Speakers
A skiascope is a device that measures the angular divergence of light rays as they pass through an optical system, such as an optical instrument or an optical system within the eye. It is used to determine the correct orientation and positioning of optical components, or to measure the correction needed for presbyopia, a condition where the lens of the eye loses its flexibility with age.
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.
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.
A verb that means to run away quickly, often in a nervous or frightened manner, often used to escape trouble or an unpleasant situation.
