WebDec 1, 2024 · Optometry Australia’s paediatric eye care reference guide lists retinoscopy as the primary refraction technique for children aged from birth to less than 7 years, and includes retinoscopy as part of suggested refraction techniques for children aged 7-14 years, along with subjective refraction. Refraction of light can be seen in many places in our everyday life. It makes objects under a water surface appear closer than they really are. It is what optical lenses are based on, allowing for instruments such as glasses, cameras, binoculars, microscopes, and the human eye. Refraction is also responsible for some natural optical phenomena including rainbows and mirages. the 10th international symposium on autophagy
