Is contact lense suitable for astigmatism

Is contact lense suitable for astigmatism? Can everyone with astigmatism can wear contact lenses? Contact lenses are widely used in correction of refractive errors, the size of buttons similar to a thin, fully transparent. It also points soft lenses and hard mirror. Soft lens with HEMA as a material, soft, can absorb moisture, wear, soft and comfortable, but easily deformed damaged, not suitable for astigmatic eyes, the hard lens of methyl methacrylate as the material, quality hard - is not easy deformation, suitable for correction of high astigmatism and keratoconus. Ordinary glasses with contact lenses does not have the characteristics are:

(1) Due to the close attachment of corneal contact lenses, and can rotate with the eye of the rotation, regardless of which direction, the total light entering the eye through the lens center, eliminating the common Ministry of glasses produced by the edge of prism effect and oblique astigmatism defects.

(2) effectively eliminate the corneal surface irregular astigmatism. Contact lens surface curvature can be specialized according to refractive request grinding to replace the irregular corneal surface curvature, thereby eliminating corneal astigmatism.

(3) contact lenses to eliminate things like the size of the gap between the two. Because of its close to the cornea, light is passed, in the retina is not wearing glasses on the imaging and were almost to see if an object does not zoom in or out, especially suitable for binocular or monocular crystal by anisometropia.

(4) contact lens light and thin, adsorbed on the corneal surface, pleasing in appearance, with actors, athletes and other special professionals is most popular among them. However, with keratitis, corneal ulcer, corneal epithelial exfoliation, corneal pannus who should not wear contact lenses, suffering from acute conjunctivitis, dacryocystitis were forbidden from wearing contact lenses. Therefore, not every short-sighted were able to wear contact lenses.
