摘要： A refraction device includes a main body, a spherical power lens coupled to the main body, an astigmatic power lens movably coupled to the main body, and a visual display coupled to the main body and oriented toward an optical pathway extending through the spherical power lens and the astigmatic power lens. The visual display is configured to display an image for testing visual acuity.
