WebMar 5, 2024 · Lenses and Refraction. In the context of microscopy, refraction is perhaps the most important behavior exhibited by light waves. Refraction occurs when light waves change direction as they enter a new medium (Figure \(\PageIndex{3}\)). WebIn refractive disorders, light rays entering the eye are not focused on the retina, causing blurred vision. The shape of the eye or cornea or age-related stiffness of the lens may decrease the focusing power of the eye. Objects may appear blurry when far away, near, or both. An ophthalmologist or optometrist determines how best to correct vision.
