WebWhat is a refraction eye exam? A refraction eye exam is an examination that measures how light refracts through your eye to determine the best prescription for corrective lenses. … WebSep 12, 2024 · For a converging lens, a ray that passes through the focal point exits the lens parallel to the optical axis (ray 3 in part (a)). For a diverging lens, a ray that approaches along the line that passes through the focal point on the opposite side exits the lens parallel to the axis (ray 3 in part (b)).
