Refractive Errors Normal vision occurs when light enters the eye and focuses directly on the retina. When light doesn’t focus properly, it results in a refractive error. WebMar 17, 2024 · Certain eye structures have refractive properties similar to water or lenses and can bend light rays into the precise point of focus that's essential for sharp vision. Most refraction in the eye occurs when light rays travel through the cornea, the curved, clear front surface of the eye. The eye's natural lens also bends light rays. gym tonic band
