Refractions research
WebObjective refraction (retinoscopy) is often used to determine the initial spherical element of refraction. However, when a patient has a recent correction that is providing good acuity, say 6/9 or better, this can be taken as the starting point. The purpose of the fi rst phase of a subjective refraction is to determine the best vision sphere ... Web5. nov 2024 · Refraction.

WebThis experiment could have been further explored by looking at different materials and how the refractive index of a material is related to the angle of refractions. This would be useful in making new materials as then scientists would know the material’s properties with respect to that of light and chart out its various uses.
