When prescribing various lenses for correcting such abnormal eye refractive power of the eye to be examined, it is necessary to prescribe them according to their respective characteristics such as spectacle lenses, hard contact lenses, and soft contact lenses.

For example, in the case of correcting astigmatism of the eye to be inspected, a spectacle lens arranged in front of, for example, about 12 mm from the surface of the cornea corrects the combined astigmatism of the cornea and lens astigmatism of the eye to be inspected. It is a thing.

Further, a hard contact lens generally has only a spherical power, and when brought into close contact with the cornea of an eye to be examined, the shape of the cornea follows the shape of the base curve surface of the hard contact lens or the base curve surface and the cornea. Only the corneal astigmatism of the eye to be inspected is corrected by the injection of the lye between the surface and the surface, and the synthetic astigmatism cannot be corrected.

Further, in the case of soft contact lenses,
Since the material is flexible, the shape of the soft contact lens itself follows the shape of the surface of the cornea, so that the corneal astigmatism of the subject's eye cannot be corrected.
