Cylindrical vs spherical lens
WebApr 10, 2024 · The great debate between spherical and cylindrical lenses has been raging for as long as these two goggle lens types have existed. Finding the perfect pair of goggles can be a game of trial and error, but understanding the differences between these two lens shapes can help make the decision process a little less daunting. WebAspherical lenses are optical lenses that feature a non-spherical but rotationally symmetric radius of curvature. Unlike spherical lenses, they have a radius of curvature that varies from the center to the edge of the lens. The variation from sphericity is often much too small to detect with the eye.
