WebOct 21, 2024 · Most refraction in the eye occurs when light rays travel through the curved, clear front surface of the eye ( cornea ). The eye's natural lens also bends light rays. Even the tear film on the surface of the eye and the fluids inside the eye ( aqueous humor and vitreous) have some degree of refractive ability. What is a Refractive Error? Watch on WebA super retardation film featuring a retardation that far exceeds the interference region. Using PET, a common material, our proprietary stretching tehcnology, and inline coating technique, this film offers superb cost performance. Combined with LED light source, this unique film eliminates tinting (rainbow pattern) caused by birefrincence.
