WebCorrective spherocylindrical lenses are commonly used to treat refractive errors such as myopia, hyperopia, presbyopia, and astigmatism. Both lenses and prisms are also frequently used to improve eye alignment and treat diplopia in strabismus. Eyeglasses also serve an important role in protecting the eyes from physical trauma and harmful radiation. Web14. jún 2024 · Refracted rays are not usually collected by the objective front lens and are lost to the final image. Now, if you use an immersion medium to replace the air gap, you can correct this mismatch. Most of the commercial immersion oils have refractive indexes of around 1.51—similar to glass.
